Re: InjectState exception within activateExternalPage
I am using Tapestry 4 rc 1. encounteriing the same problem on Solaris
server machine as posted in :
http://issues.apache.org/jira/browse/TAPESTRY-696
Strangly, its working ok on Windows development machine. However, the workaround suggested by Shawn works fine.
