RecursiveTreeNodesAdapter + Turning off default drop handling at node.

[harpritt]

Hi People

Ive just been surfing around the forum looking for some info on how to re-sequence the order of nodes within a my rich:tree using DnD... the goal is to have a tree that allows for droping of nodes between other nodes thus allow reordering as required.

So far Ive got my Rich:tree working merrily with a recursiveTreeNodesAdapter with my dropListener, and now im working on getting the reordering to work.

Ilya has proposed a cool solution in  http://community.jboss.org/message/568834#568834

Part of the solution is to turn off default drop support at the node.

I was just wondering how to do this, is this as simple as just not specifing a dropListener on the node?

Anyway as allways all help is appreciated.

PS would really welcome comments from people that have this working.

Kind Regards

Hi

Heres what i have so far.

<rich:tree style="width:100%" ajaxKeys="#{null}" ajaxSubmitSelection=

"true" switchType="client" id="checklistTree">

<rich:recursiveTreeNodesAdaptor roots=

"#{myBean.tree.rootElement}" var="ele" nodes=

"#{ele.childElements}" id="tree">

<rich:treeNode>

     <a4j:outputPanel id="upperPanel" layout="block">

          <h:outputText value="uppper" />

          <rich:dropSupport dropListener="#{myBean.dropListener}" acceptedTypes=

"all" />

     </a4j:outputPanel

<a4j:outputPanel id="contentPanel" layout="block">

<rich:dragSupport dragType="all" dragIndicator="indicator2" />

<h:outputText value="folder #{ele.id}" />

</a4j:outputPanel>

</rich:treeNode>

</rich:recursiveTreeNodesAdaptor>

</rich:tree>

Drag works fine.... but the drop doesnt.... the drop zone just wont accept the dragged element... driving me nuts..

cheers in advance

No idea why this isnt working.... driving me potty.

I guess one alternative is to create an intermediate tree that has "inbetween nodes" that is then used in the recursiveadapter....

darn it... this would have been ideal.

sorry, I forgot about one issue there which I found some time ago. check please https://jira.jboss.org/browse/RF-8582 and workaround proposed.
