Subject [jira] [Resolved] (MYFACES-2395) Cant' run two JSF portlets on the same portal page
Date Fri, 17 Jun 2011 19:17:48 GMT


Leonardo Uribe resolved MYFACES-2395.

       Resolution: Fixed
    Fix Version/s: 2.1.2

I checked it again and the right thing to do is get RenderKitFactory just once in each place
it is used, and deprecate this method. Anyway, I changed the code so now it use FacesContext
attribute map. In 1.2 version I add an additional instanceof to check that case and if it
is found recalculate the renderkit and prevent the bug (I don't know why I didn't do that
before! maybe too focus on explain why that setup was not working).

> This exception allways happen with the second portlet on the page, whichever it is. I
tried with many portlets, but so you can reproduce the problem I'm attaching the wars for
two very simple portlets.
> I'm filling this under MyFaces Core instead of Portlet Bridge because the same applications,
if deployed to use Mojarra (included in JBoss AS 4.2) and the same portelt bridge jars, work
