Question

I think i got a bug of richFaces.

I have a simple page with a tabPanel with switchType=’ajax’ and 2 (empty) tabs, the first tab only contains a textarea whose value is bound to a bean property and the tabPanel just does not work. Becoming following log messages while trying to change the tab:

info [11:31:56.919]: Received 'begin' event from <div id=form:j_id2114509110_7e08d99f ...>
info [11:31:56.953]: Received 'beforedomupdate' event from <div id=form:j_id2114509110_7e08d99f ...>
info [11:31:56.957]: Element error
<error><error-name>javax.faces.component.UpdateModelException</error-name><error-message><![CDATA[org.apache.myfaces.view.facelets.el.ContextAwarePropertyNotWritableException: javax.el.PropertyNotWritableException: ResourceBundles are read-only]]></error-message></error>
error[11:31:56.959]: Received 'error@serverError' event from <div id=form:j_id2114509110_7e08d99f ...>
error[11:31:56.961]: [200] undefined: undefined
info [11:31:56.962]: Received 'complete' event from <div id=form:j_id2114509110_7e08d99f 

when i remove the value binding, everything works as expected.
Also changing the textarea by a input box works fine
.

UPDATE: i also get a server error with switchType=’server’:

has somebody encountered such a problem, is there any workaround?

Answer 1

So, i got it!

And it is kind of a bug, but in org.apache.myfaces.el.unified.resolver.ResourceBundleResolver version 2.0.9.

The point is that my property is named ‘text’, and i have also a resource bundle called ‘text’. Additionally in the javax.el.CompositeELResolver the org.apache.myfaces.el.unified.resolver.ResourceBundleResolver is before the javax.el.BeanELResolver.

And the org.apache.myfaces.el.unified.resolver.ResourceBundleResolver.setValue(ELContext context, Object base, Object property, Object value) method does NOT check the base object and just looks for a resource bundle named as the property, in my case it finds something and peng! Exception!

It should check (base != null) and just leave.
