Hi folks! I'm pretty rusty in JSF, but came back to it for a smallish application. I'm using MyFaces-2.3.3 via TomEE-8.0-M3.
I have a pate ballotDetail.xhtml which should be bookmarkable. Invocation is http://localhost:8080/voting/ballotDetail.xhtml?dswid=-3043&ballotId=10000 dswid is from DeltaSpike and should be perfectly transparent. For the ballotId I have the following viewParam section: <f:metadata> <f:viewParam name="ballotId" value="#{ballotDetail.ballotId}"/> <f:viewAction action="#{ballotDetail.loadBallot}"/> </f:metadata> In the ballotDetail backing bean I have an Integer ballotId which initially is null. Funnily the param will not be set, but first MyFaces now invokes a getBallotId() and bombs up with a NPE during validation in phase PROCESS_VALIDATIONS. Stacktrace is as follows: org.apache.myfaces.view.facelets.el.ContextAwareELException: javax.el.ELException: Error reading [ballotId] on type ....fe.BallotDetailModel$$OwbNormalScopeProxy0] at org.apache.myfaces.view.facelets.el.ContextAwareTagValueExpression.getValue(ContextAwareTagValueExpression.java:101) at javax.faces.component._DeltaStateHelper.eval(_DeltaStateHelper.java:356) at javax.faces.component.UIOutput.getValue(UIOutput.java:67) at javax.faces.component.UIInput.getValue(UIInput.java:170) at javax.faces.component.UIInput.validate(UIInput.java:759) at javax.faces.component.UIInput.processValidators(UIInput.java:293) at javax.faces.component.UIViewParameter.processValidators(UIViewParameter.java:215) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1458) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1451) at javax.faces.component.UIViewRoot._processValidatorsDefault(UIViewRoot.java:1782) at javax.faces.component.UIViewRoot.access$600(UIViewRoot.java:81) at javax.faces.component.UIViewRoot$ProcessValidatorPhaseProcessor.process(UIViewRoot.java:1889) at javax.faces.component.UIViewRoot._process(UIViewRoot.java:1738) at javax.faces.component.UIViewRoot.processValidators(UIViewRoot.java:982) at org.apache.myfaces.lifecycle.ProcessValidationsExecutor.execute(ProcessValidationsExecutor.java:38) at org.apache.myfaces.lifecycle.LifecycleImpl.executePhase(LifecycleImpl.java:195) at org.apache.myfaces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:142) at org.apache.deltaspike.jsf.impl.listener.request.DeltaSpikeLifecycleWrapper.execute(DeltaSpikeLifecycleWrapper.java:89) at javax.faces.lifecycle.LifecycleWrapper.execute(LifecycleWrapper.java:57) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:204) I also tried to set required="false", but didn't help neither. Same Stacktrace If I initiate the ballotId with -1 then the setBallotId is properly being set in phase UPDATE_MODEL_VALUES. I don't remember such problems. Is this a new behaviour? Is it correct? Feels counter intuitive at least. txs and LieGrue, strub
