null drag value in listener

[chizzzo]

Hi, I need some help, i´ve been trying to get what is happening for two day´s but I just can´t. The event.getDragValue() function returns null.

<f:view>
 <center>
 <rich:dragIndicator id="indicator"></rich:dragIndicator>
 <h:form>
 <h:panelGrid styleClass="generalTable">
 <rich:panel>
 <rich:dataTable id="iItems" value="#{PjCreationDataBean.initItems}" var="item">
 <rich:column>
 <a4j:outputPanel style="border:1px;">
 <rich:dragSupport dragType="item" dragIndicator=":indicator" dragValue="asd">
 <rich:dndParam name="label" value="#{item.item}"/>
 </rich:dragSupport>
 <h:outputText value="#{item.item}"/>
 </a4j:outputPanel>
 </rich:column>
 </rich:dataTable>
 </rich:panel>
 <rich:panel>
 <rich:dropSupport acceptedTypes="item" dropListener="#{WeaponDropEventListener.processDrop}"
 dropValue="#{PjCreationDataBean.selectedItems}">
 </rich:dropSupport>
 <rich:dataTable id="sItems" value="#{PjCreationDataBean.selectedItems}" var="item">
 <rich:column>
 <a4j:outputPanel style="border:1px;">
 <h:outputText value="#{item.item}"/>
 </a4j:outputPanel>
 </rich:column>
 </rich:dataTable>
 </rich:panel>
 </h:panelGrid>
 <center>
 </h:form>
 </f:view>

package request;

import org.ajax4jsf.dnd.event.DropListener;
import org.ajax4jsf.dnd.event.DropEvent;
import org.ajax4jsf.dnd.Dropzone;
import java.util.ArrayList;
import rolSystem.initConfig.InitItem;
import java.util.Iterator;
/**

public class WeaponDropEventListener implements DropListener{

 /** Creates a new instance of WeaponDropEventListener */
 public WeaponDropEventListener() {
 }

 public void processDrop(DropEvent event) {
 Dropzone dropZone = (Dropzone) event.getComponent();
 ArrayList<InitItem> selected = (ArrayList) dropZone.getDropValue();
 System.err.print(selected.size());
 Object ob = event.getDragValue();
 if(ob == null)
 System.err.print("objeto nulo");
 selected.add((InitItem) event.getDragValue());

 }
}

Thanks

Hi,

Have you resolved your problem ? Because I'm actually in the same crap ;).

Any reply would be welcome. Thanks.

chizzzo, I tried the following method instead of yours

public void processDrop(DropEvent event) {
 Dropzone dropZone = (Dropzone) event.getComponent();
 ArrayList<InitItem> selected = (ArrayList) dropZone.getDropValue();
 System.err.print(selected.size());
 Object ob = event.getDragValue();
 System.out.println("DragValue " + event.getDragValue());
 System.out.println("DropValue " + event.getDropValue());
 if(ob == null)
 System.err.print("objeto nulo");

 }

and got

0DragValue asd
DropValue []

in console.

So, for me it works.

What is your environment?
