Description Elias Volanakis

When using a CompletionCombo / CompletionComboRidget the following code causes an NPE:

comboRidget.setOutputOnly(true);
comboRidget.updateFromModel();
// later
comboRidget.setOutputOnly(false);
comboRidget.updateFromModel(); // NPE because comboRidget#listBindingExternal == null

This is caused by a workaround we added earlier to handle some output-only edge case (351). Basically we are unbinding / rebinding internally. Will reconsider if we really need this.

Resolved -- had to change the SelectionTypeEnforcer mechanism quite a bit. Tests and CComboSubModuleController seem to work ok though.
