I have been hitting my head against the wall with this one for few hours already and I dont have a clue why this is happening…
Recently we have began process of moving from JBoss 4.2.3 to JBoss 6 Final. We are using JSF 1.2. I have sucessfully adapted application to new JBoss (mostly by removing some JARs from WEB-INF/lib and tunning web.xml a bit) and app starts nicely.
The problem is that some EL expressions are not being resolved, while others do. I also get 0 exceptions or warnings in the logs.
I have a bean called “mapContext” which is defined in one of the JSF xml config files. It is being created just fine. On my JSF page I have:
<h:inputHidden id="mapContextId" value="#{mapContext.webContextId}" />
and in the rendered page it becomes:
<input id="mapForm:mapContextId" type="hidden" name="mapForm:mapContextId" value="#{mapContext.webContextId}" />
As you can see, JSF tag is rendered just fine, but EL is not interpreted.
There are no logs in the server.log indicating any problems.
JSF 1.2, JSTL 1.2, Jboss 6, JDK 6.
Web.xml:
<context-param>
<param-name>org.jboss.jbossfaces.JSF_CONFIG_NAME</param-name>
<param-value>Mojarra-1.2</param-value>
</context-param>
Any help would be greatly appreciated!
More details:
Well I have doublechecked my code and configuration. Also I have added some logging to the Custom Variable Resolver I am using, to see what beans are used by JSF. Results are weird.
First of all I have enhanced my JSF page with different outputs, and it now looks like this:
<h:inputHidden id="mapContextId1" value="#{mapContext}" />
<h:inputHidden id="mapContextId2" value="#{selectionPointSymbol.width}" />
<h:inputHidden id="mapContextId" value="#{mapContext.webContextId}" />
<h:inputHidden id="mapContextId3" value="#{selectionPointSymbol4.width}" />
and is rendered as:
<input type="hidden" name="mapForm" value="mapForm" />
<input id="mapForm:mapContextId1" type="hidden" name="mapForm:mapContextId1" value="#{mapContext}" />
<input id="mapForm:mapContextId2" type="hidden" name="mapForm:mapContextId2" value="#{selectionPointSymbol.width}" />
<input id="mapForm:mapContextId" type="hidden" name="mapForm:mapContextId" value="#{mapContext.webContextId}" />
<input id="mapForm:mapContextId3" type="hidden" name="mapForm:mapContextId3" value="#{selectionPointSymbol4.width}" />
I checked the logs and I can see that mapContext is being resolved just fine by non-standard JSF tags:
12:27:24,911 ERROR [mb.ags.adf.resolvers.AGSUserResolver] AGSUserResolver asked to resolve: mapContext
12:27:24,911 ERROR [mb.ags.adf.resolvers.AGSUserResolver] AGSUserResolver delegated to: com.sun.faces.el.ChainAwareVariableResolver@ab4f3c and resulted with: mb.ags.adf.map.MbWebContext@20
12:27:24,927 ERROR [mb.ags.adf.resolvers.AGSUserResolver] AGSUserResolver asked to resolve: mapContext
12:27:24,927 ERROR [mb.ags.adf.resolvers.AGSUserResolver] AGSUserResolver delegated to: com.sun.faces.el.ChainAwareVariableResolver@ab4f3c and resulted with: mb.ags.adf.map.MbWebContext@20
(lots of them in the logs).
But there is no single log about: selectionPointSymbol or selectionPointSymbol4 (no such bean defined at all!), which are only used in standard tags.
Still no errors or warnings in the server log 🙁
More details: simple test.

Still no clue what is happening, as there are no logs indicating any problems.
Ensure of the following things:
el-*.jarin/WEB-INF/lib.web.xmlis declared conform Servlet 3.0 specification (as JBoss 6 supports).web.xmldoes not contain a context param ofcom.sun.faces.expressionFactorywhich points to a different (and apparently non-existing) EL implementation.
