Hi Antonio & Chris,
There is a bug in framework/idlitcommandbuffer__define.pro, around line 232,
where it assumes that you have the Undo/Redo operations. You can work around
this by making sure the Undo/Redo operations are registered in your
subclass:
self->RegisterOperation, 'Undo', $
'IDLitopUndo', $
ACCELERATOR='Ctrl+Z', $
IDENTIFIER='Edit/Undo', ICON='undo', /disable, $
/IGNORE_AVAILABILITY
self->RegisterOperation, 'Redo', $
'IDLitopRedo', $
ACCELERATOR='Ctrl+Y', $
IDENTIFIER='Edit/Redo', ICON='redo',/disable, $
/IGNORE_AVAILABILITY
Or, if you are brave or don't want to have these operations, you can modify
idlitcommandbuffer__define.pro by adding a check after line 232:
change this:
oUndo = self._oEnv->GetByIdentifier('OPERATIONS/EDIT/UNDO')
idUndo = oUndo->GetFullIdentifier()
to the following:
oUndo = self._oEnv->GetByIdentifier('OPERATIONS/EDIT/UNDO')
if (~OBJ_VALID(oUndo)) then $
return
idUndo = oUndo->GetFullIdentifier()
