When trying to save a semantic type on a composite actor, I get an NullPointerException. To reproduce this bug do the following:

1) drag a composite to the canvas
2) rt. click and choose 'Semantic Type Annotation'
3) choose a type to add and click the >> button to add it
4) click "ok"

The ok button will pause in the depressed form then an NPE will appear on the console. The NPE looks like this:

[java] >>> getConceptId() = urn:lsid:localhost:onto:1:1#Actor
[java] >>> getConceptId() = urn:lsid:localhost:onto:2:1#GeneralPurpose
[java] >>> getConceptId() = urn:lsid:localhost:onto:2:1#Workflow
[java] >>> getConceptId() = urn:lsid:localhost:onto:2:1#LocalInput
[java] Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
