A problem with development using Netbeans RCP: BeanTreeView

[dxwary]

hello friends,
Recently I tried to write a small application using netbeans rcp to do some data filtering job. In the programm, I use ExplorerManager and BeanTreeView component to display the model, after finishing those jobs, I find a problem, "How to open a corresponding editor topcomponet (already designed) when double clicked a node in the tree".In JTree, we can add a listener to watch the tree, find the node and then do anything we want, but I don't know how to do this using Netbeans Explorer API.
please help me, thank you.

You can override in the node getPreferredAction(), usually this action will be invoked on double clicks.
