<a:poll id="observer" enabled="#{identity.loggedIn}" interval="30000"/>
<a:outputPanel ajaxRendered="true">
<rich:dataTable var="_task" value="#{pooledTaskInstanceList}"
rendered="#{identity.loggedIn and not empty pooledTaskInstanceList}">
<h:column>
<f:facet name="header">#{messages.task_type}</f:facet>
#{_task.name}
</h:column>
<h:column>
<f:facet name="header">#{messages.task_description}</f:facet>
#{_task.description}
</h:column>
<h:column>
<f:facet name="header">#{messages.task_created}</f:facet>
<h:outputText value="#{_task.create}">
</h:outputText>
</h:column>
<h:column>
<f:facet name="header">#{messages.action}</f:facet>
<s:link action="#{pooledTask.assignToCurrentActor}" value="testas" view="/TaskList.xhtml"
>
<f:param name="taskId" value="#{_task.id}"/>
</s:link>
<h:form>
<a:commandButton action="#{pooledTask.assignToCurrentActor}" value="test">
<f:param name="taskId" value="#{_task.id}"/>
</a:commandButton>
</h:form>
</h:column>
</rich:dataTable>
<rich:spacer width="1" height="10"/>
<rich:separator height="2" lineType="dashed"/>
<rich:spacer width="1" height="10"/>
<rich:dataTable var="_task" value="#{taskInstancePriorityList}"
rendered="#{identity.loggedIn and not empty taskInstancePriorityList}">
<h:column>
<f:facet name="header">#{messages.task_type}</f:facet>
#{_task.name}
</h:column>
<h:column>
<f:facet name="header">#{messages.task_description}</f:facet>
#{_task.description}
</h:column>
<h:column>
<f:facet name="header">#{messages.task_created}</f:facet>
<h:outputText value="#{_task.create}">
</h:outputText>
</h:column>
<h:column>
<f:facet name="header">#{messages.action}</f:facet>
<s:link value="test" view="/TaskList.xhtml"
action="#{pooledTask.unassign}">
<f:param name="taskId" value="#{_task.id}"/>
</s:link>
<h:form>
<a:commandButton action="#{pooledTask.unassign}" value="test">
<f:param name="taskId" value="#{_task.id}"/>
</a:commandButton>
</h:form>
</h:column>
</rich:dataTable>
</a:outputPanel>
when use s:link/button oper this Task list throws exception : org.hibernate.SessionException: Session is closed!
if i use ajax request(a:commandButton) it's work. but oper after use refresh in Browser then throws exception : org.hibernate.SessionException: Session is closed!
i open seam log , i found org.jboss.portletbridge.seam.SeamPhaseListener close and reOpen request in once request.
log:
