ClassCastException thrown when two JSF portlets appear on the same portal page in Liferay Portal 5.2

• Type: Regression Bug
• Status: Closed
• Priority: Minor
• Resolution: Fixed
• Affects Version/s: liferay-faces-3.0.3-legacy-ga4
• Fix Version/s: liferay-faces-3.0.4-legacy-ga5
• Component/s: Liferay Faces Bridge Impl / Demos / Tests
• Labels: None

This issue is a regression in the 3.0.4-legacy-ga4 released caused by the combination of FACES-1700 and FACES-1704.

Steps to Reproduce:

• Deploy the jsf2-ipc-pub-render-params portlet in Liferay Portal 5.2 + Tomcat
• Add the Customers and Bookings portlet to a portal page
• Reload the portal page

If the bug still exists, then the portal page will not render, and the following stacktrace will appear in the server log:
