Hello, first thanks for this great framework. It's very impressive, which great stuff is provided with this framework!

Currently I try to implement full drag&drop support within one rich:dataTable with multiple rich:column. Every column is drag&dropzone. Haven't found nothing in the docs that this shouldn't be allowed - therefore I use it.....8-}
BUT: This works only for drag and drop from left to right, but not from dnd from right to left.

The problem is: if going from left to right - the normal order of listeners is triggered - first the dragListener and second the dropListener. But if I go from right to left - the first triggered listener ist the dropListener, and this throw a Nullpointer in my own code, because I assume that always the dragListener must be triggered first.
And I use the dragListener to initialize some internal variables, and the dropListener to clean them....

Here is my src from one column:

<rich:column id="slot1_day0">
 <a4j:outputPanel id="out_slot1_day0" ajaxRendered="true" style="#{record.slot1[0].styleValue}" layout="block">
 <rich:dragSupport dragIndicator=":indicator" dragType="text" dragValue="#{record.slot1[0].oid}"
 dragListener="#{prod1Handler.addToDnDList}" >
 <rich:dndParam type="drag" name="label" value="#{record.slot1[0].order_number}" />
 </rich:dragSupport>

 <rich:dropSupport acceptedTypes="text" dropListener="#{prod1Handler.addSingleOrder}" />
 <h:outputText value="#{record.slot1[0].order_number}" />
 </a4j:outputPanel>
 </rich:column>

The backing-bean prod1Handler has session-scope, if this is from relevance.

Short snippet from the start of the table, because this table is inside a rich:tabPanel. Don't know if I really need the a4j:region, but it has no side-effects. Have tried with and without this element.

<rich:tabPanel switchType="client">
 <rich:tab label="Produktion 1" id="tab_prod_1">
 <a4j:region selfRendered="true" id="region_prod_1">

 <rich:dataTable id="production1_detail"
 onRowMouseOver="this.style.backgroundColor='#F1F1F1'"
 onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"
 cellpadding="0" cellspacing="0"
 width="100%" border="0" var="record" value="#{prod1Handler.resultModel}">

dragIndicator is also used, and declared before the form-tag.

<rich:dragIndicator id="indicator" />
<h:form id="production_detail">

My environment:
Tomcat 6.0.16
JDK 1.6.0_01
MyFaces 1.2.3
RichFace 3.2.2(Snapshot from 19.06.2008 richfaces-api-3.2.2-20080619.044039-17.jar etc.)

Maybe someone can find the problemsource? Or is this a bug?

with friendly greetings 8-}
