Facing issue with a4j:keepAlive

[mitesh]

Hi all..

I am facing "View state can not be restore" popup error when i click on radio button when i use following code.

Following code shows one radio button and two text boxes in one panelGrid.

Behaviour I want is like when i click on YES then it will not show the text boxes (or PanelGrid) and when i click on NO then it will.

I use IntakeHeaderBean as KeepAlive shown in following code. If I remove IntakeHeaderBean from keepAlive then It is not showing error and working properly. But then new problem i am facing is when i clicked on radio it instanciate bean again and calles the constructor. (which i dont want to do).

<a4j:region rendered="true" renderRegionOnly="true" immediate="true">
<a4j:outputPanel ajaxRendered="true" layout="none"
 rendered="true">

<a4j:keepAlive beanName="clientLOBBean"></a4j:keepAlive>
<a4j:keepAlive beanName="intakeHeaderBean"></a4j:keepAlive>

.
:
:
<h:panelGrid columns="2">
<h:outputText styleClass="FormTitle" value="#{intakeHeaderBean.columnNames['PERSON_COMPLETING_FORM_FLAG']}" />

<a4j:region immediate="true" renderRegionOnly="true" rendered="true">

<a4j:outputPanel ajaxRendered="true" rendered="true">
<h:panelGroup id="PersonCompletingFormPanelGroup">

 <h:selectOneRadio layout="lineDirection" immediate="true"
 styleClass="FrmNormalType" value="#{intakeHeaderBean.personCompletingFormFlag}"
 valueChangeListener="#{intakeHeaderBean.personCompletingFormRadioListener}">

 <f:selectItem itemLabel="Yes" itemValue="Y" />
 <f:selectItem itemLabel="No" itemValue="N" />

 <a4j:support event="onclick" immediate="true" reRender="personCompletingPanelGrid">
 </a4j:support>

 </h:selectOneRadio>

<a4j:outputPanel layout="none">

<h:panelGrid columns="2" id="personCompletingPanelGrid" rendered="#{!intakeHeaderBean.personCompletingFormFlagBoolean}">

 <h:outputText styleClass="FrmResultsType" value="If No: " />

 <h:outputText value="" />

 <h:outputText styleClass="FrmResultsType" value="#{intakeHeaderBean.columnNames['PERSON_RELATIONSHIP']}" />

 <h:inputText styleClass="FrmNormalType"
 value="#{intakeHeaderBean.personRelationship}"
 required="#{!intakeHeaderBean.personCompletingFormFlagBoolean}" />

 <h:outputText styleClass="FrmResultsType"
 value="#{intakeHeaderBean.columnNames['PERSON_FULL_NAME']}" />

 <h:inputText styleClass="FrmNormalType"
 value="#{intakeHeaderBean.personFullName}"
 required="#{!intakeHeaderBean.personCompletingFormFlagBoolean}" />

</h:panelGrid>

</a4j:outputPanel>
</h:panelGroup>
</a4j:outputPanel>
</a4j:region>
</h:panelGrid>
:
:
</a4j:outputPanel>
</a4j:region>
