[seam-issues] [JBoss JIRA] Closed: (JBSEAM-1557) Seam is peforming a redirect in when running as a portlet, rather than using the portlet lifecycle

Seam is peforming a redirect in when running as a portlet, rather than using the portlet lifecycle -------------------------------------------------------------------------------------------------- Key: JBSEAM-1557 URL: https://jira.jboss.org/jira/browse/JBSEAM-1557 Project: Seam Issue Type: Bug Components: Core, Portal Affects Versions: 1.2.1.GA Environment: WinXP / Liferay 4.3.0 / Tomcat 6.0.13 Reporter: Neil Griffin Assignee: Wesley Hales Attachments: Manager.java Background: I found this problem when attempting to package the Seam "Registration" example as a portlet under Liferay Portal. Section 7.4.2 of the JSF 1.1 specifcation says that since redirects are not possible in the case of portlets. Nevertheless, the Seam Conversation Manager (Manager.java) is forcing the portal to redirect outside its portal pages, rather than use the portlet lifecycle. The way this would be manifested to the user would be like this: If a Seam application was contained within a portlet, and the portlet were placed on a portal page, then when the user clicks on a button that invokes navigation to a different JSF view, then the Seam application would "jump out" (so to speak) of the rectangular portlet container, and become a full-browser-page thing. This is incorrect. If a Seam application starts out as a portlet, then it must remain a portlet for its entire lifespan. In addition, the current behavior of Seam is not conforming to section 7.4.2 of the JSF 1.1. specification. Now, it might be the case that this redirect works under JBoss Portal, but it causes exceptions to be thrown under Liferay Portal. This is because Liferay Portal expects JSF-based portlets to not perform redirects, as they must not do that anyway.
