[jboss-user] [JBoss Seam] - Setting distributable in web.xml breaks Seam examples

[alex.kozlenkov]

Running 1.1.7RC1: setting  in web.xml results in the following exceptions for conversation scope components. In fact, not a single Seam example includes @Clustered components or  in web.xml. It seems like a good idea to have this regression tested somewhere.
