Is your filter the first filter in the filter chain?
Yes, it's the very first one in the chain filter. Again, the error occurs when the URL contains the ?cid=###&clr=true. The clr is the long running name that is specified in the components.xml file. The error blew up for whatever the combination of the cid=###&longRunName=true.
To resolve this problem right now, what I did what to put a blank for the long running name into the components.xml or to mod the Manager's redirect to check for the face's application for nullity.
I guess you'll have to open a JIRA case and submit some code because I'm not following how to reproduce this.
