[seam-issues] [JBoss JIRA] Commented: (SEAMFACES-179) s:viewaction not invoked with Mojarra 2.1.2

[ https://issues.jboss.org/browse/SEAMFACES-179?page=com.atlassian.jira.plu... ] Brian Leathem commented on SEAMFACES-179: ----------------------------------------- Summary of an IRC conversation with Pete Muir and Ed Burns, and Lincoln Baxter: pmuir states this is a problem caused by making a re-entrant call on the thread to the faces lifecycle. The viewAction component does this by starting/executing a new JSF lifecycle within the existing JSF lifcycle: https://github.com/seam/faces/blob/develop/api/src/main/java/org/jboss/se... With respect to re-entrancy, edburns says: edburns: JSF relies on the re-entrancy model model of the servlet spec pmuir: pre Servlet 3 that is quite clear, the servlet container will never reuse a thread before a request has ended pmuir: in Servlet 3 I believe that requests can be suspended edburns: the JSF spec has not been updated to account for the re-entrancy capabilities in Servlet 3. pmuir: weld assumes that we don't have re-entrancy Rather than trying to mess with Weld to allow this re-entrancy to work, I suggested the JSF EG discuss any changes required at the spec level to accommodate this behavior. Lincoln suggested: lincolnthree: in prettyfaces i just use a phase listener, unfortunately you lose out on the whole component tree goodness lincolnthree: I'm comfortable saying that I think viewAction is a hack to get around the real problem lincolnthree: which is that JSF doesn't support phase-level actions like a front-controller -- This message is automatically generated by JIRA.
