How to a4j:keepAlive

[jmiguel77]

Hi

I don't know if i am using a4j:keepAlive in the correct manner, but it seems to me that it is not storing the values in the way it should

Let's assume this

<a4j:keepAlive beanName="modulosFormasDataManager" />
<h:form>
<rich:tabPanel>
 <rich:tab id="modulosTab" label="Modulos" actionListener="#{modulosFormasController.tabActionListener}">
 <rich:dataTable id="modulosDataTable" binding="#{modulosFormasController.modulosDataTable}" value="#{modulosFormasDataManager.modulos}" var="item" cellspacing="0" cellpadding="2" styleClass="cb-rich-table" headerClass="headerCell" columnClasses="headerCell,dataCell,dataCell,dataCell,dataCell,dataCell,dataCell" rowKeyVar="row">
 <rich:column id="moduleRowColumn" style="width:20px">
 <f:facet name="header"><h:outputText value=" " escape="false"/></f:facet>
 <h:outputText id="moduleRowNumber" value="#{row+1}" />
 </rich:column>
 <rich:column id="moduleNameColumn">
 <f:facet name="header"><h:outputText value="Módulo" escape="false"/></f:facet>
 <h:outputText id="moduleName" value="#{item.nombre}" />
 </rich:column>
 <rich:column id="moduleStateColumn">
 <f:facet name="header"><h:outputText value="Estado" escape="false"/></f:facet>
 <h:outputText id="moduleState" value="#{item.estado}" />
 </rich:column>
 <rich:column id="moduleResponsibleColumn">
 <f:facet name="header"><h:outputText value="Responsable" escape="false"/></f:facet>
 <h:outputText id="moduleResponsible" value="#{item.responsable}" />
 </rich:column>
 <a4j:support id="moduleSelectRowSupport" event="onRowClick" data="#{modulosFormasDataManager.selectedModulo}" actionListener="#{modulosFormasController.selectRowListener}" onsubmit="setSelectedRow(this)" oncomplete="alert(data);" />
 </rich:dataTable>
 </rich:tab>
<rich:tab>
some other code
</rich:tab>
</rich:tabPanel>

the modulosFormasDataManager is a request scoped bean that has some properties to work with my data; basically is just a data holder; it is also a managed property of the page backing bean

 <managed-bean>
 <managed-bean-name>modulosFormasDataManager</managed-bean-name>
 <managed-bean-class>com.casabaca.administration.web.common.ModulosFormasDataManager</managed-bean-class>
 <managed-bean-scope>request</managed-bean-scope>
 </managed-bean>

 <managed-bean>
 <managed-bean-name>modulosFormasController</managed-bean-name>
 <managed-bean-class>com.casabaca.administration.web.controller.ModulosFormasController</managed-bean-class>
 <managed-bean-scope>request</managed-bean-scope>
 <managed-property>
 <property-name>modulosFormasDataManager</property-name>
 <property-class>com.casabaca.administration.web.common.ModulosFormasDataManager</property-class>
 <value>#{modulosFormasDataManager}</value>
 </managed-property>
 </managed-bean>

the ModulosFormasDataManager bean has a property named selectedRow, so when i click on a row of the table, i use an actionListener to define that property from the rowData of the dataTable. I assume that if i click on a row and set the value properly in the modulosFormasDataManager, and then i click in the other tab the selectedRow of the modulosFormasDataManager must be present but it is not, the property is null

even more, if i click on a row, i assume the value is setted in modulosFormasDataManager.selectedRow and stays there for as long i remain in the page; but if i click in another row and check the last value of the selectedRow property it is always null

Am i missunderstanding the use of the a4j:keepAlive ??? how is it suppossed to be used ??

thanks a lot
