Using Parameter Mapping you can get selected elment at runtime.

To achieve this you have create an action at design time, and bind that action to TreeNodeType.

Create event parameter of type ContextNodeElement (Search for JAVA native Types) for that action .

You have to map this event parameter to the event handler parameter

if (firstTime) {

IWDTreeNodeType nodeType =

(IWDTreeNodeType) view.getElement("<NodeTypeID>");

nodeType.mappingOfOnAction().addSourceMapping(

"path","<parameterName>");

}

In OnAction method you will get selected element's reference from the event handler's parameter.

Get the value of the required attribute from this selected element and set it to input field.

Vijay,

Do you use recursive node for tree or "regular" node/sub-nodes?
