commandLink in datatable not calling 'action'

[SO...@ameren.com]

The code snippet below is a stripped down section of a data table using a
command link with an action binding.

<h:dataTable id="idPendingTasksTable"
value="#{taskListBean.pendingDeployList}" var="task" >
    <h:column>
        <f:facet name="header">
            <h:outputText value="Task"/>
        </f:facet>
        <h:commandLink action="#{taskListBean.details}" id="idTaskLink"
value="#{task.taskId}">
        </h:commandLink>
    </h:column>
.
.
</h:dataTable>

If the managed bean is request scope, JSF doesn't seem to call the action
method of the managed bean when the link is clicked.   If the bean is
session scope, then the action method gets called.  Is there a way to use a
datagrid with command links that will invoke the action method binding on
click when the managed bean is request scope?  If not and I need to stick
with session scope here, I'll have to manually remove the bean from the
session after I'm done, as the link only needs this bean for the one
request.

I'd be interested in opinions about whether the action method binding
should work in request scope or not.  If it should work , any ideas about
what I may be doing wrong or ways to track down why the invocation is
skipped would be appreciated.  I've turned on debug logs and haven't seen
anything helpful, but that's likely due to my newness to myfaces anyway.

Thanks in advance for any opinions or info...

Problem is, that your bean loses the "pendingDeployList" during 
requests. Try to use the <x:dataTable> and set the "preserveDataModel" 
attribute to "true".
