Action method not getting called inside the dataTable

Hi Friends

I am having trouble in calling the action method from command link inside
datatable.

The code of the DataTable is 

<h:dataTable id="siteDetailTable1"
value="#{siteRequirementBean.detailHeadQuarterList}" var="details"
cellpadding="1" cellspacing="1" width="100%">
<h:column>
<h:panelGrid columns="1" width="100%" columnClasses="none,tableRowOdd"
rowClasses="tableRowEven,tableRowOdd">
<h:panelGroup>
<h:outputText value="Name: " />
<h:outputText value="#{details.name}" style="width: 55%" />
</h:panelGroup>
<h:panelGroup>
<h:outputText value="Location: " />
<h:outputText value="#{details.location}" style="width: 55%" />
</h:panelGroup>
<h:panelGroup>
<h:outputText value="Description: " />
<h:outputText value="#{details.description}" style="width: 55%" />
</h:panelGroup>
</h:panelGrid>
</h:column>
<h:column>
<h:commandLink action="#{requirementDisplay.viewDetailedRequirement}">
<h:outputText value="VDR" />
</h:commandLink>
</h:column>
</h:dataTable>

The managed beans siteRequirementBean & requirementDisplay both are in
request scope.

The datatable has two columns. In the first column there 3 labels which
displays some information. In the second column there is a command link.
This command link is binded with an action method of managed bean. The page
gets displayed with all the components including the commandlink , but on
clicking the command link the action method is not getting called. The page
gets refreshed & comes back again.

Infact I tried putting in arbitrary string in the action method’s name
attribute of command link. There was no error & the page came back again on
clicking the link. 
If the same command link is kept outside data table then the action method
gets called.

Command Button also shows the same behavior as command link.

Please give your valuable inputs…..

Thanks in Advance
Amit :)

Hi,

when using t:saveState scope of the bean will be longer than request
but shorter than session. Exactly what you need when staying on the
same page.

Usage:

<t:saveState value="#{yourBean}"/>

cheers,

Gerald

Re: Action method not getting called inside the dataTable

Hi 

Thanks a lot Adrin for your reply !!! 

I changed the scope of bean from request to session. Now the action method
is getting called. But I found that both the beans(siteRequirementBean &
requirementDisplay) needs to be in session scope. But the command link is
only calling the action method of requirementDisplay bean. So when only
requirementDisplay is kept in session scope,  action method is not getting
called. Also my whole application is built on the top of logic that the bean
would be in request scope. So changing the scope of bean from request to
session would be night mare & real problem. So can you please tell me is
there any other way out of it…

Thanks
Amit

The bean that holds the data mode should be in session scope.
