Hi I am new to richfaces picklist , My scenario is to load hashmap and by selecting the key value i need to load it in picklist. After getting the key i need to generate dynamic jasper report. My problem is while try to load the map value i end up with Typecast exception with the examples i came accross.
<rich:pickList id="pickList1" value="#{xxx.selectionBean.fieldNameList}" sourceCaption="Fields to be Selected for Report"
targetCaption="Selected Fields for Report" listWidth="165px" listHeight="100px" orderable="true" converter="pickListConvertor">
<f:selectItems value="#{xxx.commencementworkBean.commencementList}" var="s"
itemLabel="#{s.key}" itemValue="#{s.value}" />
<f:converter converterId="pickListConvertor" />
</rich:pickList>

I’m working on upgrading our application vaadin version from 7.7.24 to 8.13.3. We’ve completed all the dependency issues and i’m able to start the application in locally.
We have a textbox that is showing up the Event data.
Here is the class file that i'm using:
#Entity
#Table(name = "changelog")
public class ChangelogEvent extends BaseEntity
{
#Column(name = "remote_ip")
private String remoteIp;
#Column(name = "remote_host")
private String remoteHost;
#Column(name = "event")
#Enumerated(EnumType.ORDINAL)
private ChangelogEventType eventType;
#Column(name = "entity_type")
private String entityType;
public ChangelogEvent()
{
}
public ChangelogEvent(String remoteIp, String remoteHost, ChangelogEventType eventType)
{
this.remoteIp = remoteIp;
this.remoteHost = remoteHost;
this.eventType = eventType;
}
public String getRemoteIp()
{
return remoteIp;
}
public void setRemoteIp(String remoteIp)
{
this.remoteIp = remoteIp;
}
public ChangelogEventType getEventType()
{
return eventType;
}
public void setEventType(ChangelogEventType eventType)
{
this.eventType = eventType;
}
public String getRemoteHost()
{
return remoteHost;
}
public void setRemoteHost(String remoteHost)
{
this.remoteHost = remoteHost;
}
public String getEntityType()
{
return entityType;
}
public void setEntityType(String entityType)
{
this.entityType = entityType;
}
}
And here is my ChangelogEventType.java file that defined ChangelogEventType enum:
public enum ChangelogEventType
{
CREATED("Created"),
UPDATED("Updated"),
DELETED("Deleted"),
LOGIN("Login"),
LOGOUT("Logout"),
LOGIN_RETRY("Login Retry"),
ACCOUNT_LOCKED("Account Locked"),
PASSWORD_EXPIRED("Password Expired"),
PASSWORD_CHANGED("Password Changed");
private String text;
ChangelogEventType(String text)
{
this.text = text;
}
public String getText()
{
return text;
}
public static ChangelogEventType fromString(String text)
{
if (text != null)
{
for (ChangelogEventType event : ChangelogEventType.values())
{
if (text.equalsIgnoreCase(event.text))
{
return event;
}
}
}
return null;
}
}
Here is the code that i'm using for binding the values into textfield.
eventType = createTextField("Event", COLUMN_WIDTH);
binder.forField(eventType)
.withNullRepresentation("None")
.bind(ChangelogEvent::getEventType, ChangelogEvent::setEventType);
Is there any way to bind the Enum to textbox ?
You need to write custom converter and use it in Binder using withConverter method, in your case something like:
class StringToChangelogEventTypeConverter implements Converter<String, ChangelogEventType> {
#Override
public Result<ChangelogEventType> convertToModel(String fieldValue, ValueContext context) {
// Produces a converted value or an error
ChangelogEventType event = ChangelogEventType.fromString(fieldValue);
if (event != null) {
// ok is a static helper method that creates a Result
return Result.ok(ChangelogEventType.fromString(fieldValue));
} else {
// error is a static helper method that creates a Result
return Result.error("Please enter a number");
}
}
#Override
public String convertToPresentation(ChangelogEventType event, ValueContext context) {
// Converting to the field type should always succeed,
// so there is no support for returning an error Result.
return event.getText();
}
}

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

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:

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.

Action class should have the following three properties.
• [inputName]File
• [inputName]FileName
• [inputName]ContentType
[inputName] is the name of the file tag(s) on the JSP. For example, if the file tag's name is uploadphoto, the properties will be as follows:
• File uploadphotoFile
• String uploadphotoFileName
• String uploadphotoContentType
String filePath = servletRequest.getRealPath("/");
File fileToCreate = new File(filePath, this.uploadphotoFileName);
FileUtils.copyFile(this.uploadphotoFile, fileToCreate);
The problem I have is that I am trying to have a multi select data grid column which will have a List objects (productsEntitled).
I've got the products to display properly by providing a buildSelect custom function to populate my Edit Dialog Box when a user click edit on a record.
When I have the column with the multi select <sjg:gridColumn name="productsEntitledListModel on my grid, the save functionality does not work and does not save. I don't see any errors on the browser console nor on the java console.
Any help will be appreciated as I am unable to find out what the problem is, I de-compiled the entire show case jar and nothing that helps with this issue.
My model look like this:
#Entity
#Table ( name = "USERS")
public class User {
private Long id;
private String name;
private String username;
private String password;
private String sourceIp;
private Device device;
private List<Product> productsEntitled;
