how to get dynamic values for reRender in a4j

[meenak]

In one of our pages we have around six textareas and we have to reRender only the textareas where the text is entered when we click on the command link .
So i need to get the list of the ids that should be reRendered dynamically.

here is the sample code :


<h:inputTextarea id="man_comm1" value="#{emp.empstate.comment3}" disabled="#{focal.edit3}" rendered="#{emp.empstate.rencom3}" rows="5" cols="40"/>
<h:inputTextarea id="man_comm2" value="#{emp.empstate.prevComment3}" rows="5" cols="40" rendered="#{emp.empstate.rencom3}" readonly="true"/>





<a4j:commandLink styleClass="button" reRender="#{emp.empstate.ren}" action="#{emp.empstate.updatecomments}">
<h:graphicImage value="/images/button_update.jpg" styleClass="button" />
<f:param name="sid" value="#{emp.empstate.model.employee.personSeqId}"/>

</a4j:commandLink>

please specify the problem more preciselly.. I see you use reRender pointed to some collection. It's right way. Just fill it while action execution.

sorry the alignment was not proper

Here is the sample code :


<h:inputTextarea id="man_comm1" value="#{emp.empstate.comment3}" disabled="#{focal.edit3}" rendered="#{emp.empstate.rencom3}" rows="5" cols="40"/>

<h:inputTextarea id="man_comm2" value="#{emp.empstate.prevComment3}" rows="5" cols="40" rendered="#{emp.empstate.rencom3}" readonly="true"/>




<a4j:commandLink styleClass="button" reRender="#{emp.empstate.ren}" action="#{emp.empstate.updatecomments}">
<h:graphicImage value="/images/button_update.jpg" styleClass="button" />
<f:param name="sid" value="#{emp.empstate.model.employee.personSeqId}"/>
</a4j:commandLink>


Thank you in advance

Hi Shaik,

Thank you for reply.

In reRender, we are just passing one name(id) of textarea to {emp.empstate.ren} to check whether we could pass this from bean to jsf page. We found that we could successfully pass it.

Would it be possible to tell us how to get dynamic values based on the input?
