How to reset the client state from a server action?

Hi,
I have a piece of server code looking very strange.

In a server Action I operate on the source model (it adjusts the position of many elements). So after finishing this I need a complete refresh on the client side. My code looks currently like this:

public class BPMNResetRoutingActionHandler extends AbstractActionHandler<BPMNResetRoutingAction> {
    @Inject
    protected BPMNGModelState modelState;

    @Override
    protected List<Action> executeAction(final BPMNResetRoutingAction actualAction) {

        // update source model.....
        ................

     
        // Force a complete refresh of the GModel state....
        modelState.refreshGModelState(); // Full rebuild of the GModel and update the root element of my GModelState
        List<Action> resultAction = new ArrayList<>();
        resultAction.add(new SetDirtyStateAction(true, SetDirtyStateAction.Reason.OPERATION));
        resultAction.add(new UpdateModelAction(modelState.getRoot()));
        return resultAction;
    }

}

I do:

• a full rebuild of the GModel
• update the root element of my GModelState
• I call this.execute(new SetDirtyCommand()); on my GModelState object that is inherited from DefaultGModelState.
• and I create to actions to set the DirtyFlag and update the model

With less code it does not work.

What would be the 'normal' way to tell the client to rerender the complete model?

Ah.... maybe I found the solution by myself.

• you should not implement an Action but an Operation
• and you should not implement an AbstractActionHandler but a GModelOperationHandler

It looks that this solves my problem. No more need to care about DirtyStates and UpdateModelActions....
