NullPointerException at CompositeComponentTagHandler

[rcholewa]

Hi

I've recently started to explore RF 4 capabilities and encountered a problem with a4j and composite at the same page.

At first I've created simple page to test ajax and it worked like a charm:

        <h:form>

            <h:inputText id="in" value="#{testBean.value}">

                <a4j:ajax event="keyup" render="out" />

            </h:inputText>

            <h:outputText value="#{testBean.value}" id="out" />          

        </h:form>

Then, I've added one, almost empty composite component and ajax ceased to work

        <comp:testComponent/>

        <h:form>

            <h:inputText id="in" value="#{testBean.value}">

                <a4j:ajax event="keyup" render="out" />

            </h:inputText>

            <h:outputText value="#{testBean.value}" id="out" />          

        </h:form>

At the client side a4j:log prints:

debug[14:34:03.091]: New request added to queue. Queue requestGroupingId changed to j_idt7:in

debug[14:34:03.091]: Queue will wait 0ms before submit

error[14:34:03.216]: [200] class java.lang.NullPointerException:

info [14:34:03.216]: Received 'complete' event from <input id=j_idt7:in ...>

and at the server exception is:

java.lang.NullPointerException at com.sun.faces.facelets.tag.jsf.CompositeComponentTagHandler.createMetaRuleset(CompositeComponentTagHandler.java:250)

I've tried with "4.0.0.Final" and "4.1.0-SNAPSHOT" versions of the maven bom.

Have you got any ideas what's wrong ?

any thoughts ?

it would be good to see complete log.. however I believe that the problem in composite component and not in RF tags placed on the same page. richfaces-showcase uses composite components and it works for us.

it seems setting javax.faces.FACELETS_REFRESH_PERIOD to non zero value do the job
