My use case is that the grid provides the swimlanes for BPMN process diagram. When I have finished modelling the process and it’s signed-off I would like to be able to lock it.

I started trying this by locking the frame I had put around the swimlanes - but that only locked the frame, not the swimlanes or the process artefacts.

I have a sort-of workaround by adding the swimlanes (grid) to a Layer and locking the layer. I have to drag a selection field around the swimlanes (rather than selecting the swimlanes object) otherwise the connection lines are not added (presumably the lines are not *in* the grid because they may cross between cells). I notice though that although I cannot select or move the grid as whole in a locked layer, I can add or move rows and columns because these remain in the Default layer. So the solution is not unfallible. It seems that items can be added to an already locked layer (which is handy) but cannot be removed from the locked layer (which is correct behaviour) - you have to unlock, move the it)em(s) to the Default layer, then lock the lockable layer.
