Drag-N-Drop + Conversation

[bsmithjj]

How do I maintain conversation state while using drag-n-drop? Is this possible or should I just use session scoping?

Thanks,

anybody?

What is your problem while performing this task? share additional info and example if you can please.

[bsmithjj]

My problem is simple, everytime I execute a drag-n-drop using richfaces, a new conversation is started on the server side. I would guess there is probably some way of communicating the conversation ID to JSF, I've even set a hidden input variable in my form to transmit the conversation ID but it's not 'working'.

I wouldn't ask here, but hey, the relevant info is not in the manual or the live demo.

Help?

Thanks,
Brad Smith

One more thing, in the manual, http://labs.jboss.com/file-access/default/members/jbossrichfaces/freezone/docs/devguide/en/html_single/index.html#dndParam
, it says:

6.37. < rich:dndParam >
6.37.1. Description

This component is used for passing parameters during drag-and-drop operations.

The questions here is who gets the parameters? are these request parameters?

I've tried this:

<rich:dndParam name="conversationId" value="#{conversation.id}"/>

but that doesn't solve my conversation-state issue...

[nbelaevski]

rich:dndParam components are aimed to customize drag indicator. Try to use f:param instead.

[bsmithjj]

well, I tried f:param

 <rich:dragSupport dragIndicator="indicator" dragType="availablePivot" dragValue="#{column.column}">
 <rich:dndParam name="label" value="#{column.label}"/>
 <f:param name="conversationId" value="#{conversation.id}"/>
 </rich:dragSupport>

and

 <rich:dropSupport id="pivotCols" dropValue="#{column}" acceptedTypes="availablePivot"
 dropListener="#{evergreenUserPivotTable.addPivotColumn}"
 reRender="availablePivotCols,selectedPivotCols,pivottedData">
 <f:param name="conversationId" value="#{conversation.id}"/>
 </rich:dropSupport>

no luck. A new conversation is generated for each drag-n-drop event.

Thanks

Can you please check if parameter is submitted? That can be done using Firebug (see Net tab) or similar tool.

[bsmithjj]

Immediately after the drop succeeds, I can see this request in firebug:

It doesn't look to me like the conversationId parameter is being sent; also, the tags are as stated in my last post on this.

Suggestions?
Thanks,
