 </rich:dataTable>

Te jsp code for my modal panel , which is on the same page but a different form is as below :

<rich:modalPanel id="modalPanel">
 <f:facet name="header">Tag Scenario</f:facet>
 <a4j:keepAlive beanName="searchResultsBean" />
 <a4j:keepAlive beanName="scenarioRecordBean" />
 <h:form>
 <h:panelGrid id="tagScenario" columns="2">
 <h:outputText value="The Scenario is saved with a contextual id :" />
 <h:outputText value="The Scenario is saved with a contextual id :" />
 <h:outputText value="Name:" />
 <h:inputText value="#{scenarioRecordBean.name}" />
 <h:outputText value="Tag" />
 <h:inputText value="#{scenarioRecordBean.email}" />
 </h:panelGrid>
 <h:panelGrid>
 <a4j:commandLink value="Close"
 onclick="#{rich:component('modalPanel')}.hide()" />
 </h:panelGrid>
 </h:form>
 </rich:modalPanel>

When I invoke the jsp from my application I get the following error :
