             Summary: [DMN Editor] Decision Navigator dock: Optimize the `ExpressionEditorChanged` event
                 Key: DROOLS-2465
                 URL: https://issues.jboss.org/browse/DROOLS-2465
             Project: Drools
          Issue Type: Enhancement
            Reporter: Guilherme Carreiro
            Assignee: Guilherme Carreiro
            Priority: Minor


The `ExpressionEditorChanged` it's being fired many times.

Check the scenario:
When the `DMNGridLayer.select(GridWidget)` method is called, it calls `BaseGridWidget.select()`. This will trigger the `ExpressionEditorChanged` X times, where X is the number of grids on the layer. This is not optimal.

Check the same problem in the `deselect` method.
