problem

JS Error: this.getSegmentGrid(...) is undefined

steps to reproduce

1. Open a task
2. Open a segment
3. Leave the task
4. Open the add new task wizard
5. Enter a task name
6. copy that task name

reason

The problem is that the copy handler for the segment editing is registered on first task open, that handler is still active after leaving the task. And if the segment grid does not exist any more, that error happens.
