rich:tree state

[mafym]

Hi!

I am having issues in keeping the state of a rich:tree.

<rich:tree id="tree" eventsQueue="queue" value="#{valuation.root}" var="item"
 treeNodeVar="node" switchType="client" ajaxSubmitSelection="true" stateVar="stateVar"
 adviseNodeOpened="#{treeStateController.adviseTreeNodeOpened}"
 adviseNodeSelected="#{treeStateController.adviseTreeNodeSelected}"
 changeExpandListener="#{treeStateController.changeExpandListener}"
 nodeSelectListener="#{treeStateController.nodeSelectListener}"
 toggleOnClick="true" rowKeyVar="rk"
 style="width:870px">

the changeExpandListener is not triggered when the tree triangle icon for expand/collapse is pressed, only when the node itself is selected (clicked).

How to call changeExpandListener when the tree triangle icon for expand/collapse is pressed?

Thanks!

Hi,

You are using switchType="client" together with ajaxSubmitSelection="true". This means that expansion using icons happens solely on the client, while selection does ajax submission, thus updating server with the new state of tree nodes. Either use switchType="ajax" or switchType="server" or add a button/a4j:support that will do actual submit.
