prerender() executes for ViewController not rendered when navigating to
page/bean not implementing ViewController
-----------------------------------------------------------------------------------------------------------------

Key: SHALE-371 URL: http://issues.apache.org/struts/browse/SHALE-371 Project: Shale Issue Type: Bug Components: View Affects Versions: 1.0.4-SNAPSHOT Environment: Windows XP Pro, Tomcat 5.5, JDK 1.5.0_04, MyFaces Reporter: Stan Zapryanov

Not sure if this is a bug but it looks like it.

When navigating to a view (JSF) not implementing the ViewHandler framework from
a ViewController t(JSF/bean) that does, currently the prerender() method gets
executed on the viewcontroller that you are leaving (that won't get rendered).

My guess is that currently the old FacesConstants.VIEW_NAME_RENDERED entry
remains in the request map even though you are not rendering that viewconroller,
and that triggers the execution of prerender().

Here is a suggested fix (that I have NOT tested) and I woudn't know if it may
brake other stuff..

In the setupViewController() method of the ViewViewHandler class:

vc = vr.resolveVariable(context, viewName); if (vc == null) { if (log.isDebugEnabled()) { log.debug(messages.getMessage("view.noViewController", new Object[] { viewId, viewName })); // ----PROPOSED FIX (not tested) ---- context.getExternalContext().getRequestMap()
.remove(FacesConstants.VIEW_NAME_RENDERED); //------END OF FIX------- } return; }

Hope all makes sense and was helpful.

Cheers!
