Subject NullPointerException when adding a Shell project
Date Mon, 21 Sep 2009 19:49:13 GMT
I am using Apache Continuum 1.3.4 (Beta) running under Tomcat 5.5.28 on linux

When trying to add a new Shell project, I occasionally get a
NullPointerException and half the time, it looks like my project get
added fine (e.g. I am able ignore the error and continue with adding a
build definitions and running them.)

Here is the stacktrace from URI:
http://localhost:8080/continuum13/addProject.action#
