DeleteOperationImplementation error

I've seen this old post in the forum http://forums.netbeans.org/viewtopic.php?t=25232&start=0&postdays=0&postorder=asc&highlight=deleteoperationimplementation, but I think that is not the same case because I don't have any way to access the code at the moment the files are deleted.

It's true that may be caused by windows file locking, but as I said before, I don't have any way to access the code that deletes the files in DeleteOperationImplementation.

The only solution I see is to make this process out of the ActionProvider, as a custom Action and add it in the getActions() method in node project.

Any help would be appreciated.
