Seen on Windows XP with Gavotte 070115_19 and JDK 1.5.0_10:

1. Open a WSDL document in the Partner view.
2. Add a partnerlinktype by clicking the Add PartnerLinkType button.
3. Define a new porttype name in the right partner's PortType field. Enter
4. Right click on the right Role widget. 
==> Nothing happens. No delete option is available (context menu, I assume?). 

This feature is described in the details for issue 89418 in DT-UC-9 of the
functional spec:
http://alaska.stc.com:10000/alaska/attach/WSDLEditorGavotteSpec/WSDLEditor+Functional+Spec.pdf.

1. User selects the role widget. This selects the whole role widget
column.
2. User hit delete key.
3. User right clicks and hit delete key. (I'm assuming 2 and 3 are ORed and key
should be menu option?)

Also in HL-UC-12:

Select the role. There will be a UI to allow delete of role (right click pop up
action) or hit delete key.

Specs and UI should match. (Same issue for porttype in issue 92476.)
