Bug 12775 [Dialogs] double click behaviour in move dialog (package view)
I double-clicked on a project, but instead of expanding the project and showing the children (source folders), it accepted the project as the target and commited OK. I think it's more natural that double clicking on projects, packages, etc. would expand/unexpand the node.
