I think I have stumbled upon a problem in Glamour. When selecting an entity that is in the model but not shown in the Tree presentation, there is a DNU when setting the selection port to the entity. To reproduce the problem:

- execute the following script in Moose then right click and select "select in tree" on a number not displayed in the Tree presentation.

The problem might arise due to the fact that all model entities do not have their morph nodes when using showOnly option. Can you please have a look?
