Description mgottval 2014-03-31 13:07:18 UTC 
I used this Producer-Consumer portlets to check Public render parameters.
https://github.com/gatein/gatein-portal/tree/master/examples/portlets/ipc

Steps to reproduce:
1. Create new page with Producer portlet on it.
2. Create new page with Consumer portlet on it.
3. Insert parameter into form in Producer portlet, the parameter is propagated into the page where Consumer is. But it is not propagated into URL. When change to Consumer page, I get an error "Action process encountered an error" and get exception. 

IllegalArgumentException: No null string array accepted

I couldn't reproduce reported issue.

Please, let me know if there is special step/environment needed to repeat the error.

Thanks !

I can't find any special environment. I happens to me every time, but the parameters are working. 
In the ProducerPublicRenderParameterPortlet during processAction 
String newPublicParameter = request.getParameter("newPublicParameter"); 
newPublicParameter is evaluated and set as render parameter, but then it is evaluated again and the newPublicParameter is null. (I added logging in the processAction to one line, and I get :"paramName1", null - null is evaluated for the second time)

We couldn't reproduce issue with a clean session of Chrome browser.
