Hi

well for defining the path you need to create a context attribute say "selectedElement" and map it of Java Native type.

I guess you have missed out this step of creating "selectedElement" as a context attribute. It is there in the tutorial :).

Anyway detailing the steps to be done.

To open the View Designer, double-click TreeView in the project structure.

1 Choose the Actions tab page.

2 Choose New to create a new action with the name LoadChildren and choose Next.

4. To add a new parameter, choose New. Give this parameter the name element "selectedElement" and for

Type, choose .

5. In the dialog box that appears, select Java Native Type, then choose Browse... In the

next dialog box that appears, enter IFolderContentElement .

6. Choose OK twice and Finish twice.

7. Repeat steps 3 to 6 for another action with the name Select and the parameter

selectedElement of the same type as in LoadChildren.

Once you do this then you will be able to get the value of the selected element.

Hope that helps you. Let me know if you require some help.

regards
