wiring problem?

Redeployed a project and all of a sudden getting this error:
[POP.003.0160] Failed to resolve wiring for property “queryString”

And also:
[POP.001.0002] A “java.lang.NullPointerException” occurred with the Message “at com.webmethods.caf.faces.portlet.FacesPortlet.getLifecycle(FacesPortlet.java:189)”

Any ideas on how to resolve/fix this - its cryptic

I have exactly the same problem, can someone help me with this?
