Description Michael Jastram CLA 2012-01-03 15:57:13 EST 
Easy to reproduce:

1. Open a ReqIF document
2. Open a Spec
3. Close the Spec
4. Reopen the Spec
5. Try to add a new element.
6. this will result in the following:

Caused by: org.eclipse.swt.SWTException: Widget is disposed
	at org.eclipse.swt.SWT.error(SWT.java:4282)

There is a workaround: Close the ReqIF and start all over.
