A DESCRIPTION OF THE PROBLEM :
It is possible to use a TransferHandler to transfer data using cut, copy and paste keypresses. These work by creating dummy drag and drop events that are sent via the transfer handler. Cut actions export data with a MOVE drop type, and copy actions export data with a COPY drop type.

The new Transferhandler.importData() method accepts a TransferSupport which provides detailed information about a drop action. Unfortunatly, if the action was initiated by a cut or copy action, the drop type information is unobtainable. Any call to getDropAction() throws an exception. Since this data should be available, the TransferSupport should return this valuable information regarless of whether is this a true drop or one initiated through cut or copy.
