doesn't work
-------------------------------------------------------------------------------------
Key: RF-6260
URL: https://jira.jboss.org/jira/browse/RF-6260
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.3.1
Reporter: Alexander Dubovsky
Assignee: Nick Belaevski
Source:
<rich:scrollableDataTable id="scrolltable" value="#{sdTable.value}"
var="item">
<rich:column width="100px">
<f:facet name="header">
<h:outputText value="Name" />
</f:facet>
<a4j:outputPanel layout="block">
<rich:dragSupport
dragType="itemDD" dragValue="#{item.make}">
<rich:dndParam
name="label" value="#{item.make}" />
</rich:dragSupport>
<rich:dropSupport
acceptedTypes="itemDD" dropValue="#{item.make}"
dropListener="#{sdTable.processDrop}" reRender="scrolltable" />
<h:outputText
value="#{item.make}" />
</a4j:outputPanel>
</rich:column>
</rich:scrollableDataTable>
processDrop:
public void processDrop(DropEvent event) {
String dragId = event.getDragValue().toString();
String dropId = event.getDropValue().toString();
Car droppedItem = null;
Car draggedItem = null;
for (Car item : value) {
if (item.getMake().equals(dropId)) {
droppedItem = item;
}
if (item.getMake().equals(dragId)) {
draggedItem = item;
}
}
if (droppedItem != null && draggedItem != null) {
value.remove(draggedItem);
value.add(value.indexOf(droppedItem), draggedItem);
}
# Drag some row and drop it in other place.
Result: dropListener was called, but table was not rerendered after that.
