hi, i’m following your examples on adding events to a diagram:

var modelerInstance = new BpmnModeler({
  container: container,
});

importDiagram(modelerInstance, diagram);
modelerInstance.on('element.click', elementClickHandler);`

how can i remove that event listener?

Thanks in advance for your help

Hey @batusai513,

you can do the following:

var eventBus = modelerInstance.get('eventBus');

eventBus.off('element.click', elementClickHandler);

We use the eventBus service for our event communication channel. You can use it directly to attach listeners through .on or .once and then remove them with off.

Cheers,
Ricardo
