my scenario is like this... i have worksheet.jsp page, which contains list of employees. which is having datatable.
<t:dataTable id="curEmployees" value="#{focal.employeeStates}" var="empstate">
<h:commandLink id="usercomments" action="#{focal.displayUserComments}" >
<h:outputText value="#{empstate.model.employee.emailId}"/>
<f:param name="sid" value="#{empstate.model.employee.personSeqId}"/>
</h:commandLink>
when i click on employee mail id , i am going to usercomments.jsp turu action focal.displayUserComments.
in the usercomments.jsp page i have another datatable, with one update and back button.
<t:dataTable id="curEmployees" value="#{focal.commentstates}" var="comstate" binding="#{focal.modelTable}">
<h:column id="head">
<h:outputText value="#{comstate.model.commentType.commentTypeDesc}"/>
</h:column>
<h:column id="txtarea">
<h:inputTextarea id="comment" value="#{comstate.comment1}" rows="5" cols="40" readonly="#{comstate.model.editable=='N'}"/>
</h:column>
</t:dataTable>
<h:commandLink id="upd_but" action="#{focal.updateComment}" styleClass="button">
<h:graphicImage value="/images/button_update.jpg" styleClass="button" />
</h:commandLink>
<h:outputLink id="dashboard_jump" value="#{facesContext.externalContext.requestContextPath}/pages/worksheet.faces">
<h:graphicImage value="/images/button_back.jpg" styleClass="button" />
</h:outputLink>
managed bean method i am calling when clicked on update button is public String updateComment() throws Exception
{
HttpServletRequest request = getHttpServletRequest();
HttpSession session = request.getSession(false);
pseqid=(String)session.getAttribute("empid");
int count=modelTable.getRowCount();
CommentState cbean[]=new CommentState[count];
for(int i=0;i<count;i++)
{
modelTable.setRowIndex(i);
System.out.println("Model Data ... "+modelTable.getRowData().toString());
cbean[i]=(CommentState)modelTable.getRowData() ;
cbean[i].updateComment(pseqid);
}
return "commentsuccess";
}
here CommentState is a Stateful session bean.
i am getting the above stated error.. when i am clickin on Back button to go back to worksheet page.
Help me...>
