Decide on the shared clipboard

What should we do?

In Camunda Modeler, the clipboard is shared between BPMN diagrams. This means that you can copy an element from diagram_1.bpmn and paste it to diagram_2.bpmn.

However, you cannot easily copy an element with Camunda properties to a Zeebe diagram (and Zeebe properties to a Camunda diagram respectively) as this leads to errors. For example, zeebe:FormDefinition does not have any execution meaning within Camunda Workflow Engine. Because of that, we’ve decided to not include the shared clipboard in https://github.com/camunda/camunda-modeler/pull/2107.

I can see three different options how to solve this problem:

• disable shared clipboard (as in https://github.com/camunda/camunda-modeler/pull/2107)
• allow to copy and paste elements but ignore process engine-specific properties (this requires additional work)
• try to convert the elements (rather infeasible)

Why should we do it?

Let’s make an informed decision to replace the temporary solution or leave it as it is.

That’s what I would test first. So sth like:

if (!moddle.canCreate(propertyOrElement)) {
  return false;
}

This could have been a workaround for #2283
