Hello i am new in smart gwt and now we are migrate from smartgwt 2.1 to smart gwt 3.1p
and i have got problem :
java.lang.UnsupportedOperationException: Can not convert element 0 of
the array to a JavaScriptObject. Instances of class
`com.test.ListDTO'
can not automatically be converted. Please see the SmartClient
documentation of RPCRequest.data for a table of Java types that can be
converted automatically.
someone write :
treeNode.setAttribute(TODO, listDTO.getLis());
how i can fix that code ?
The setAttribute method of the TreeNode tries to convert the list elements internally. That fails with your own domain objects. You can try to set the list with this helper method:
com.smartgwt.client.util.JSOHelper.setObjectAttribute(treeNode.getJsObj(), TODO, listDTO.getLis());
Now the Java object is set on the JavaScriptObject. To get this object back you can call:
treeNode.getAttributeAsObject(TODO);

I have some ExtJs component.
I set itemId for it, but id is autogenerated.
Now Ext.getCmp('autogenerated-id') returns my component.
But Ext.ComponentQuery.query('#autogenerated-id') returns an empty array.
But:
Ext.ComponentQuery.query('[id=assets-information-form-1918]') again returns my component. :)
I use ExtJs 6.5.3 classic.
It seems like itemId config property hides autogenerated id from Ext.ComponentQuery, so they become mutually exclusive.
I don't need other means for search or advice to set id for the component, to write letter to Sencha support or to write post on their forum.
I need:
Means to force my Ext.ComponentQuery.query('#autogenerated-id') to
find the Component for which getId() returns 'autogenerated-id'.
If it is not possible by design, I need a link to some documentation
describing this behavior, a link to some bug report, or a filename and line number in ExtJs sources + a little snippet copy/paste from there.
From the documentation
Summary Provides searching of Components within Ext.ComponentManager
(globally) or a specific Ext.container.Container on the document with
a similar syntax to a CSS selector. Returns Array of matching
Components, or empty Array.
Ext.ComonpentQuery.query('#itemId') returns and array. Your cold above is using the auto-generated id of the component. The # indicates to query based on the component itemId and not the component id.
Try
Ext.ComponentQuery.query('assets-information-form-1918');
which will return an array, as noted in the documentation.
Ext.getCmp()
This is shorthand reference to Ext.ComponentManager#get. Looks up an
existing Ext.Component by id
Therefore it returns the component object.
Ext.ComponentQuery.query('#itemId')[0] would return the first object in the array.
Ext.ComponentQuery is the Sencha preferred method because it is more powerful when used as it does return an array so you an also query items by xtype and other attributes.
Angular manages our objects somewhere in the Scope, but I need to manually set and get the object that controls a component so I can automatically set all the component's info once I download its model from the web through JSON.
Example
#Component (selector: 'my-component')
class MyComponent {
//component fields
}
As the user interacts with <my-component> it changes its fields. I want to be able to get the whole MyComponent object with its fields to save them like this
MyComponent comp = magicComponentGetterFunc('my-component');
String json = encodeJson (comp); //I do this this redstone_mapper
I think ngProbe can do that.
ElementProbe ep = ngProbe('my-component');
You can can find examples by visiting the links at https://pub.dartlang.org/packages/angular where ngProbe or ElementProbe is mentioned.
The CHANGELOG.md mentions that ngProbe is necessary for animation but the codedoc on the ElementProbe class still states that it is for testing and debugging (see https://github.com/angular/angular.dart/blob/96c0bcc7b6b0c3501b2c4799f425de8cd2e4dc0c/lib/core_dom/view_factory.dart#L259)
To get the JSON you either have to implement a getter/method (for example toJson) that returns the JSON you want or use some of the available serialization solutions (see State of Serialization and Deserialization of JSON in Dart).
If you want to do that this usually indicates that your approach works against the way Angular should be used.
I'm using JsonSerializer to convert an Object to a JSON String but the order is wrong. The attributes are automatically sorted alphabetically but I want them in the order they have been listed in the class (e.g. "endPoint" should not appear before "startPoint").
When I call JsonSerializer. I only see 4 methods (toJava or toJson). I tried doing includes with the order but it doesn't work/I'm not doing it right. The way I'm doing it is like this:
return new String[]{"errorDescription", "searchResultRecord.billOfLadingNumber",
"searchResultRecord.bookingNumber", "searchResultRecord.advancedManifest",
"searchResultRecord.inboundCustomsClearanceStatus", "searchResultRecord.cargoReleaseStatus", "searchResultRecord.freightChargeReleaseStatus",
"searchResultRecord.container.containerNumber", "searchResultRecord.container.latestEvent.event",
"searchResultRecord.container.latestEvent.location", "searchResultRecord.container.latestEvent.time"};
As you can see there is obj.obj.attr parts being included. But when I try to run this code I only see "errorDescription" in the output string. I then tried "searchResultRecord" without attributes but it only showed 2 of the attributes in the output :x
Any idea how to fix the order so its not alphabetical? All examples online seem to be from an older version of the class with more accessible methods~ Thanks for any info.
You can try using
#XmlType(propOrder={"startPoint", "endPoint"})
on the class you defined as #XmlRootElement. Those attributes and any other you want will sorted as you defined on propOrder.
I'm using streamedcontent to render a byte sent from JSF then send it back as a streamed content as following:
<p:graphicImage value="#{manage.bytesToStreamedContent(car.image)}"/>
where image is the byte array of the image stored in the database
backing bean:
public StreamedContent bytesToStreamedContent(byte[] bytes)
{
InputStream is = new ByteArrayInputStream(bytes);
StreamedContent image = new DefaultStreamedContent (is, "image/jpeg");
return image;
}
But I'm not getting the image in the JSF page. I got this message appearing in the server log:
WARNING: JSF1091: No mime type could be found for file dynamiccontent. To resolve this, add a mime-type mapping to the applications web.xml.
and:
SEVERE: Error in streaming dynamic resource.
can you please help me out here, I cant find any useful info regarding this issue
PS:
Im using the following libraries:
Mojarra 2.1.3
PrimeFaces 3.1.1
Glassfish 3.1
Found where the problem was. The problem wasn't in the graphicimage. It was because the graphicimage tag is being loaded dynamically (similar issue when trying loading from datatable). Dynamic images cannot be rendered directly in datatable or datagrid. (Workaround is to assign a param and bring the images from the id).
However, the solution is here
This is an odd problem and I don't think that adding the mime-type to web.xml will fix it. It is listed as both a bug in PrimeFaces with a target for 3.2
http://code.google.com/p/primefaces/issues/detail?id=3546
And it is also listed as an open bug in Mojarra 2.1.1. There is a patch submitted for this bug however it looks like you will have to manually apply the code to the Mojarra 2.1.1 source and build it. One would think that this would be fixed in 2.1.3 however, Glassfish may have its own prebundled Mojarra implementation that is still at an earler version and your application may be using this instead.
http://java.net/jira/browse/JAVASERVERFACES-2103
EDIT:
You can just pass the byte[] directly as an argument to the method like that. What you can do though is pass the id of the car as a param and then retrieve that car and fetch the bytes from the Car entity. The reason for this is because the graphicImage actually renders as an HTML img tag and this occurs in a separate HTTP request from the request for the JSF page. Download and install the Firebug plugin for Firefox and you will see this occur, the page is requested, then subsequent requests occur for the images after the page is retrieved. Because of this ViewScoped and RequestScoped beans cannot be accessed in this way, however a request parameter can still be passed with the necessary information needed to retrieve the Car bytes for the image.
<p:graphicImage value="#{manage.bytesToStreamedContent}">
<f:param name="item_id" value="#{car.id}" />
</p:graphicImage>
Now in your managed bean property you can get the car id, and after you get the car id you should be able to get the right car.
public StreamedContent getBytesToStreamedContent() {
String id = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("item_id");
//Now get the car with the id
}
In general, it's not a great idea to create the StreamedContent in the getter for graphicimage. The image will be fetched in a separate request from the rest of the content, meaning variables depending on iterators will not work. This means that in the relevant call to bytesToStreamedContent the bytes array will be null/empty. If you put breakpoints inside the method you will probably see that in the last call there is no data in bytes.
You need to make sure the image is generated while you still have access to all the needed content and then store it in a way that you get retrieve it again in bytesToStreamedContent. Whether or not this will fix the problem and actually work for you is hard to say without seeing the rest of the code. I would start by trying to remove the byte array argument and returning a static image to confirm that this is the problem.
Using Struts 2.1.6, xwork 2.1.2 and ognl 2.6.11
In my struts action I have a Map that I am fetching elements from using OGNL. If the key I am using to fetch with does not exist in the map then OGNL returns an empty object array, that OGNL converts to a string and I get the object reference java.lang.Object#6.... This occurs in several places and seems to be the the map having the value generic specified as an Object. This is not something I can change.
I have traced the problem for a while, but when I ended up deep into the guts of the OGNL code and I did not see a light at the end of the tunnel. Currently I am going to go with an ugly hack of checking the string return to see if it starts with "java.lang.Object#" and if so return an empty string. I don't like the solution but thats what time permits.
Has anyone encountered a similar problem?
Also, where did OpenSymphony go? updates to their webiste appear to have dried up, the user forums say they are being converted to Google Groups no later than Nov-12-09
This is a problem with null values: if value is null, default behavior is to create a value using default constructor. Since the value type of your map is Object, new Objects are created where null is.
In order to stop this behavior:
use #CreateIfNull( value = false )
use mapName_CreateIfNull=false in classname-convertion.properties file.
