Drag & Drop retrive dnd params javascript

[haoues01]

Hi,

I implemented a jsp page using dnd and it works fine, excepted the fact that is very very slow (my collection contains around 1300 items and when I drop an item I have to submit the whole region )! So, I want to know if there is a way to retrieve only the id of the item to drop (using dnd params transmitted to the drag indicator or something else) and then submit only my destination collection???

I hope I've been clear. Any help would be great. Thans in advance for your attention.

Has anyone tried to extract parameters from drag indicator using pure javascript?

Using latest 3.2.0 snapshots you may surround your drop zone to region. We've fixed impossibbility to use dnd between regions. Now it can be performed even from different forms

Thanks for reply !

I downloaded the latest snapshot

richfaces-ui-3.2.0-20070925.235823-1-bin.zip 25-Sep-2007 20:19 8.3M

but it doesn't work entirely; I can retrieve the drop value but not the drag value.
Is it normal ? Below my JSP code (simplified):

<!-- HERE THE DRAG ZONE -->
<a4j:region id="home_mem_re" >
<a4j:outputPanel id="home_mem_op" layout="block" >
...
<rich:dataTable id="home_mem_dt" value="#{...}" var="teamMem" ... >
<rich:column>
<a4j:outputPanel layout="block">
<rich:dragSupport dragIndicator=":indicator"
dragType="member" ragValue="#{teamMem.id}" >
<rich:dndParam name="label" value="#{teamMem.desc}" />
</rich:dragSupport>
<h:outputText value="#{teamMem.desc}" />
</a4j:outputPanel>
</rich:column>
</rich:dataTable>
...
</a4j:outputPanel>
</a4j:region>

<!-- HERE THE DROP ZONE -->
<a4j:region id="home_player_re" >
<a4j:outputPanel id="home_player_op" layout="block">
<rich:dataTable id="home_player_dt" value="#{...}" var="gpWpr" .../>
...
<rich:column>
<a4j:outputPanel layout="block">
<rich:dropSupport acceptedTypes="member" dropValue="#{gpWpr.val}"
dropListener="#{...}" reRender="home_player_op" />
<h:outputText value="#{gpWpr.replacedDesc}" />
</a4j:outputPanel>
</rich:column>
...
</rich:dataTable>
...
</a4j:outputPanel>
</a4j:region>

Thanks in advance for attention.

I tried with the latest version 16-Oct-2007 02:35 and it's not better; the drop value is null (from the drop event).

Actually, dragging between regions either as forms doesn't work for now: http://jira.jboss.com/jira/browse/RF-961. We'll see what we can do with that

Ok,

Actually the latest 3.2.0 snapshots I got is not stable (http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4095870#4095870)
and it seems that the dnd between region/form wouldn't be available till 2008, right?
