Description

Deleting a widget using WTemplate.removeWidget() fails with a NullPointerException when:

  • There are empty-bound variables in the template instance
  • The empty-bound variables are iterated over before the widget to be removed is found

This is because bindEmpty() sets the map value to null.

This can be resolved with a check, or the function can be modernized using streams.
