RE: Tree2 node selection [again]

[rahmoune patrick]

Hi,

 

Here is how I managed this issue. If I remember, it may has been already discussed here.

 

Assuming you have a binding of your tree2 component in your managed bean,

 

you can add an actionListener to the commandLink for each facet of your tree

 

something like

 

<h:commandLink immediate="true" actionListener="#{yourBean.setNodeSelected}">

...

 

in the setNodeSelected method

 

public void setNodeSelected(javax.faces.event.ActionEvent ae)

//just add

tree.setNodeSelected(ae);

 

And now you should be able to retrieve the selected node

 

using

 

tree.getDataModel().getNode();

 

Hope this help

 

I welcome any better solution

Hi group,

in my example i have tree2-component with selectable nodes through
nodeToggler-attribute.

varNodeToggler="t" binding="#{foo.uidata}" >
[...]

So far this works well.

From another controll (commandButton) i want to edit the current
selected node, so have to access the selected node.

But i'm wondering, if want to access the current selected node with
UITreeData.getNode()-method, i always get 'null'.

The only way to get the selected node is during the select-action
processing phase (calling a action method).



value="#{node.identifier}" />
[...]

//
//the only moment to get the selected noted from the uidata-component !
public void selectedNode(String id) {
// ignoring the parameter
selectedNode = uitreedata.getNode();
}


After this the uitreedata.getNode() always returns 'null'.
IMHO this is a bug, because the selection-state is obviously saved
somewhere (at least in the nodetoggler). And so the uidata should
represent this.

By the way : how to access the nodetoggler ? There is no binding and no
way to access this through the UITreeData-Component !?

regards

Ronald
