[bpel-dev] question about commands

["Danilov, Oleg V" <oleg.v.danilov@xxxxxxxxx>]

Hi,

 

I’m wondering why BPELCopyCommand extends AutoUndoCommand, moreover, doExecute method takes care about unfo/redo?

 

      public void doExecute() {

            TransferBuffer transferBuffer = fBpelEditor.getTransferBuffer();

            undo = transferBuffer.getContents();

            transferBuffer.copyObjectsToTransferBuffer(fOriginalObjects, fBpelEditor.getExtensionMap());

            redo = transferBuffer.getContents();

      }

 

From my point of view the ‘copy’ command should not change undo stack. Any objections?

 

Thanks,

  Oleg.
