By clicking on the diagram node in hierarchy in project explorer.. Action
provider is getting invoked. But when i right click on the diagram
file(not the node) -default.mmd itself at top level without collapsing
the hierarchy,again actionprovider is not called.
I have modified the trigger point and possible children values as
below.(not sure if it is correct ) But still this action provider is not
used. Will i have to use a different action provider for files.?
