I'm having a problem with Flash Scope when I try to set a flash scope variable and then do a redirect. In the console, I get the following trace...
com.sun.faces.context.flash.ELFlash setCookie
WARNING: JSF1095: The response was already committed by the time we tried to set the outgoing
cookie for the flash. Any values stored to the flash will not be available on the next request.
The idea is pass an id from the first page (search page) to the second page, but if I cancel using immediate, I get the mentioned log, and the flash counter is not incremented anymore.
The code:

I have a AutoCompleteTextView that I give it 2 different adapters depending on the amount of text that is being present at the textview - if it has 0 characters I want it to display a list of "recently searched" strings adapter, while if it has more than 1 characters I want it to display auto completion list.
My getRecentlySearchedQueries method along with the RecentSearchedViewModel-
private List<String> recentlySearchedQueries = new ArrayList<>(); // pasted from the top of the class
#Override
public void getRecentlySearchedQueries() {
recentSearchViewModel.getAllQueries().observe(getActivity(), databaseRecentlySearchList -> {
if (databaseRecentlySearchList == null) {
return;
}
for (int i = 0; i < databaseRecentlySearchList.size(); i++) {
Log.d("localDBValue", "Added value - " + databaseRecentlySearchList.get(i).toString() + "\n");
String query = databaseRecentlySearchList.get(i).getQuery();
recentlySearchedQueries.add(query);
}
//Log.d("localDBValue", "recent search list value - " + recentlySearchedQueries);

So, what I am doing here is for start getting all values inside my local DB and adding them to my String list that is part of the adapter. So far so good.
The issue I am facing is that the adapter won't show the amount of strings available in the list that populates it. In fact, it sometimes shows a view half-cut with wierd information, sometimes does not show anything and sometimes shows part of the corrent information. What am I missing?
Another thing I am facing is that the "recently searched" adapter won't work when clicking on the AutoCompleteTextView - it only works when typing and deleting values so the char length is 0. How can I make it work from start of focus?
Here is the way I am populating the information to the ViewModel -
/**
* Shows the searched products following
*/
#Override
public void getSearchedProducts(String searchedQuery) {
MarketplaceUtils.getSearchedProducts(searchedQuery, marketApiCalls, false, initialSearchTake, initialMarketplacePage, new MarketplaceUtils.OnProductsFetchCompleteListener() {
#Override
public void onSuccess(List<MiniProductModel> list) {
if (!searchedQuery.equals(currentSearchedText))
return;
if (list == null) {
//reaching here means we do not have a result to show to the UI so we empty the list.
currentProductList.clear();
productsAdapter.notifyDataSetChanged();
return;
}
if (searchedQuery.length() > 3 && searchAutoCompleteStrings.contains(searchedQuery)) {
Log.d("localDBValue", "searchedValue - " + searchedQuery);
recentSearchViewModel.insert(new RecentSearchModel(searchedQuery));
}
mPresenter.setDiscoverProductsLayoutVisibility(View.GONE);
currentProductList.clear();
currentProductList.addAll(list);
productsAdapter.notifyDataSetChanged();
}
#Override
public void onError(Throwable throwable) {
Log.d("searchedProducts", throwable.getMessage());
}
});
}
The default behaviour for #Insert method of Room is OnConflictStrategy.ABORT - so what I did is to implement equals() method to verify that the RecentSearchModels that are being compared are compared by their string value. Still does seems to effect anything.

If I am using the same query without any parameters, the code is working perfectly. I can see the database changes instantly in frontend. The issue is coming after added a parameter in Where clause.

i'm using spring-boot-starter-data-elasticsearch (1.4.0.M3).
I'm unable to get the version (_version in elasticsearch query result) of a document using the annoation "version".
Any idea why the annotation isn't working ?
f.e.:
#GwtCompatible
#Document(indexName = "myIndexName")
public class Catalog implements Serializable {
private List<GroupProduct> groups;
#Id
private String uuid;
#Version
private Long version;
#Field(type = FieldType.Nested)
private List<Product> products;
private String label;
#NotEmpty
private String organizationUuid;
private List<String> organizationUnitUuids;
private Date updateDate;
private List<VAT> vats;
public Catalog() {
}
public List<GroupProduct> getGroups() {
return groups;
}
public List<Product> getProducts() {
return products;
}
public Date getUpdateDate() {
return updateDate;
}
public void setGroups(List<GroupProduct> groups) {
this.groups = groups;
}
public void setProducts(List<Product> products) {
this.products = products;
}
public void setUpdateDate(Date updateDate) {
this.updateDate = updateDate;
}
public List<VAT> getVats() {
return vats;
}
public void setVats(List<VAT> vats) {
this.vats = vats;
}
public String getUuid() {
return uuid;
}
public void setUuid(String uuid) {
this.uuid = uuid;
}
public String getOrganizationUuid() {
return organizationUuid;
}
public void setOrganizationUuid(String organizationUuid) {
this.organizationUuid = organizationUuid;
}
public String getLabel() {
return label;
}
public void setLabel(String label) {
this.label = label;
}
public List<String> getOrganizationUnitUuids() {
return organizationUnitUuids;
}
public void setOrganizationUnitUuids(List<String> organizationUnitUuids) {
this.organizationUnitUuids = organizationUnitUuids;
}
public Long getVersion() {
return version;
}
public void setVersion(Long version) {
this.version = version;
}
}
Spring Data Elasticsearch (as of version 2.0.2) seems to have only partial support for the #Version annotation. If you annotate a document with a version field, it will be used when indexing a document. It will tell Elasticsearch that the document being saved is that specified version. If the new version is less than or equal to the version of the current document, Elasticsearch will throw a VersionConflictEngineException.
Unfortunately, Spring does not appear to populate this version field when a document is retrieved. As far as I can tell, this makes the version annotation useless. Perhaps the project will add this support in the near future. In the meantime, I have found a workaround by extending the default ResultMapper that Spring uses:
public class ExtendedResultMapper extends DefaultResultMapper {
protected MappingContext<? extends ElasticsearchPersistentEntity<?>, ElasticsearchPersistentProperty> mappingContext;
public ExtendedResultMapper(MappingContext<? extends ElasticsearchPersistentEntity<?>, ElasticsearchPersistentProperty> mappingContext) {
super(mappingContext);
this.mappingContext = mappingContext;
}
#Override
public <T> T mapResult(GetResponse response, Class<T> clazz) {
T result = super.mapResult(response, clazz);
if (result != null) {
setPersistentEntityVersion(result, response.getVersion(), clazz);
}
return result;
}
#Override
public <T> LinkedList<T> mapResults(MultiGetResponse responses, Class<T> clazz) {
LinkedList<T> results = super.mapResults(responses, clazz);
if (results != null) {
for (int i = 0; i < results.size(); i++) {
setPersistentEntityVersion(results.get(i), responses.getResponses()[i].getResponse().getVersion(), clazz);
}
}
return results;
}
private <T> void setPersistentEntityVersion(T result, Long version, Class<T> clazz) {
if (mappingContext != null && clazz.isAnnotationPresent(Document.class)) {
PersistentProperty<ElasticsearchPersistentProperty> versionProperty = mappingContext.getPersistentEntity(clazz).getVersionProperty();
if (versionProperty != null && versionProperty.getType().isAssignableFrom(Long.class)) {
Method setter = versionProperty.getSetter();
if (setter != null) {
try {
setter.invoke(result, version);
} catch (Throwable t) {
t.printStackTrace();
}
}
}
}
}
}
You can tell Spring to use this version instead of the default mapper as follows:
#Autowired
private Client client;
#Bean
public ElasticsearchTemplate elasticsearchTemplate() {
MappingElasticsearchConverter converter = new MappingElasticsearchConverter(new SimpleElasticsearchMappingContext());
ExtendedResultMapper mapper = new ExtendedResultMapper(converter.getMappingContext());
return new ElasticsearchTemplate(client, converter, mapper);
}
Note that the version is only populated for Get or Multi-Get requests. Search results do not include version information.
You could also use this same approach to extract other information from the GetResponse objects.
Using this code, if you get a document and then try to save it back, it will fail unless you increment the version.

When I am trying to do the following:
SessionFactory sessionFactory = new SessionFactory(modelsPackageName);
Session session = sessionFactory.openSession(url);
String cypher = "MATCH (u:User {code: {CODE}})-[h:HAS_PROPERTY]->(pg:PropertyGroup) " +
"RETURN u, h, pg";
Map<String, Object> params = new HashMap<String, Object>();
params.put("CODE", "fc48b19ba6f8427a03d6e5990bcef99a28f55592b80fe38731cf805ed188cabf");
// System.out.println(Util.mergeParamsWithCypher(cypher, params));
User u = session.queryForObject(User.class, cypher, params);
The user Object (u) never contains any properties (PropertyGroup entity is not mapped).
What am I doing wrong?
Any help would be appreciated.
Regards,
Alex
If you're using queryForObject return just one column- the object, in your case u.
Neo4j OGM 1.x does not support mapping of custom query results to domain entities, so you will have to return the entity ID, and then do an additional load-by-id specifying a custom depth.
OGM 2.0 (currently 2.0.0-M01) does support mapping custom query results to entities. Your query will remain the same (i.e. return u,h,pg) but instead you'll use the query() method that returns a Result. From the result, you'll be able to get your User entity by column-name u and it'll be hydrated with the PropertyGroups it is related to.
Update:
The dependencies for OGM 2.0.0-M01 are
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j-ogm-api</artifactId>
<version>2.0.0-M01</version>
</dependency>
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j-ogm-core</artifactId>
<version>2.0.0-M01</version>
</dependency>
Be sure to read the about the configuration changes since you're upgrading from OGM 1.x http://neo4j.com/docs/ogm/java/2.0.0-M01/#reference_setup

I'm kinda new to JSF and primefaces and I'm running into a very annoying problem.
I'm making a very basic application to learn a bit more about primefaces. I have a simple form that has several textual input fields, two datepickers and one dropdown (selectOneMenu).
Everything works all values are put in the backing bean when I submit the form, except for the value from the dropdown menu. The setter for that item is never called. And the application does not call the public void saveNewActivity(ActionEvent evt) method on the controller as defined on the commandbutton. When I however remove or comment out the dropdown menu in html it does call that method (but the field for the dropdown menu is obviously null).
I've been trying things for nearly two days, and still can't get this to work properly.
I have the following code (snippets):
My html/jsf code
<div id="newActivitycontent">
<h:form id="newActivityForm">
<h:messages id="messages"/>
<table>
<tr>
<td>Gebruiker:</td>
<td><p:selectOneMenu value="#{plannedActivityController.newActivity.organiser}}"
converter="#{userConverter}">

My userbean:

#Override

}
And the converter used by the selectOneMenu:
#Named
public class userConverter implements Converter{
#Inject
private PlannedActivityController activityController;
#Override
public Object getAsObject(FacesContext facesContext, UIComponent uiComponent, String s) {
for (UserBean user : activityController.getUsers()) {
if(user.getId().toString().equals(s)) {
return user;
}
}
return null;
}
#Override
public String getAsString(FacesContext facesContext, UIComponent uiComponent, Object o) {
if(o instanceof UserBean) {
UserBean user = (UserBean)o;
return user.getId().toString();
}
return "";
}
}
The problem is here. Look closer. This is invalid EL syntax.
value="#{plannedActivityController.newActivity.organiser}}"
This should however have thrown a PropertyNotWritableException on submit something like this:
javax.el.PropertyNotWritableException: /test.xhtml #25,39 value="#{plannedActivityController.newActivity.organiser}}": Illegal Syntax for Set Operation

This exception should have been logged to the server log. By default this will however not end up in an error page for the enduser because JSF/PrimeFaces have by default no form of feedback to enduser in case of exceptions which are thrown during ajax requests. You should however be able to see it in actual ajax response body in webbrowser's builtin HTTP traffic monitor.
The JSF utility library OmniFaces offers a FullAjaxExceptionHandler for the very problem of total absence of feedback on exceptions during ajax requests. You may find it useful. When I tried to recreate your problem, I was been presented a clear error page so that I don't need to dig in server log or HTTP traffic monitor for clues.
