Unable to deselect elements in a GModelCreateOperationHandler

[rsoika]

I am using currently org.eclipse.glsp.server:1.1.0.RC10 and have problem to deselect elements in a GModelCreateOperationHandler

The situation is the following:

• The user selects 2 Elements in the diagram
• Opens the command palette
• And selects a "Create Edge Command"

After that operation the elements are still selected which I want to avoid.

For that reason I added a SelectAction with the elements to be deselected and the new edge element.

  @Override
    public Optional<Command> createCommand(final CreateEdgeOperation operation) {
        return commandOf(() -> executeOperation(operation));
    }

    protected void executeOperation(final CreateEdgeOperation operation) {
      ....
      ArrayList<String> deselectedElementsIDs = new ArrayList<String>();
      deselectedElementsIDs.add(sourceId);
      deselectedElementsIDs.add(targetId);
      actionDispatcher.dispatchAfterNextUpdate(
           new SelectAction(
                   List.of(edgeId),
                   deselectedElementsIDs)
      );
    }

But this does not work. The interesting thing is that my new selection (the newly created edge) is selected. So as a result now 3 elements are selected.

How can I achieve that the two initial elements are deselected?

I found the reason for the problem by myself. The Java Server Side is correct and works as expected.

But I have had another javaScript component on the client side that implemented a SelectionListener. And this custom component caused the problem.

So everything is fine - all works as expected, but sometimes I forget about the client... ;-)
