RD commented on TOMAHAWK-514:
-----------------------------
I have tried to do that yesterday, but as soon as I've set breakpoints on the
two methods, Eclipse (or jboss, I don't know) has begun to operate in a strange
manner.
I get the following error messages, whether I use breakpoints or not:
12:10:52,468 ERROR [[Faces Servlet]] Servlet.service() for servlet Faces

> Method not triggered by s:valueChangeNotifier
> ---------------------------------------------
>
> Key: TOMAHAWK-514
> URL: http://issues.apache.org/jira/browse/TOMAHAWK-514
> Project: MyFaces Tomahawk
> Type: Bug
> Versions: 1.1.5-SNAPSHOT
> Environment: JBoss 4.0.4.GA
> MyFaces 1.1.3
> Tomahawk+Sandbox 1.1.5 snapshot
> Reporter: RD
>
> This is a snippet from my JSF page:
> <h:selectOneMenu id="vertragid" required="true"
> value="#{rufnummerEditBean.vertragid}"
> disabled="#{!(rufnummerEditBean.editable)}"
> onchange="submit()" immediate="true">
> <s:valueChangeNotifier
> method="#{rufnummerEditBean.changeVertragid}"/>
> <f:selectItems
> value="#{rufnummerEditBean.vertragidList}"/>
> </h:selectOneMenu>
> This is the associated piece of code:
> public void changeVertragid(ValueChangeEvent event) {
> Integer newval=(Integer)(event.getNewValue());
> if(debugInfo) System.out.println("changeVertragid "+newval);
> setVertragid(newval);
> List<SelectItem> listTarifs=getTarifidList();
> if(listTarifs.isEmpty()) setTarifid2(null);
> else setTarifid2((Integer)(listTarifs.get(0).getValue()));
> }
> When selecting some value in the combo box Vertragid, the method
> changeVertragid is not called (or else I would have seen the output of
> System.out.println in the log).
> I have also tried with immediate="false", but there is no difference.
> What should I do to fix this?
