<a4j:commandLink actionListner is not getting called

[icai]

Hi,

I am trying to implement sorting in one of datatables. But the commanadlink's action listner doesn't get called, though on clicking the links the control reaches to the managed bean.
Following is my code snippet :

<rich:dataTable
 cellpadding="0" cellspacing="0"
 width="100%" border="0"
 id="transtable"
 binding = "#{backing_CustSearchBean.transtable}"
 onRowMouseOver="saveref(this);onOver('#{backing_CustSearchBean.transtable.rowIndex+1}');"
 rendered="#{backing_CustSearchBean.strrendered == 'true'}"
 onRowMouseOut="onOut('#{backing_CustSearchBean.transtable.rowIndex+1}');"
 headerClass="bluebar"
 var="oppList" value="#{backing_CustSearchBean.prod_sesn_lst}"
 style="margin-top: 5px; cursor: pointer;overflow: auto;"
 styleClass = "dt_normal"
 rowClasses="searchcusttoprow,searchcustrows"
 ajaxKeys="#{backing_CustSearchBean.ajaxSet}"
 onRowClick="showOppSelected('#{oppList.opp_id}','#{backing_CustSearchBean.transtable.rowIndex+1}');showAllWheel('rtform:form2:transwheel');"
 columnClasses="searchcustcols,searchcustmidcols,searchcustcols,searchcustmidcols,searchcustcols,searchcustmidcols"
 >
 <f:facet name="header">
 <rich:columnGroup
 columnClasses ="searchcustcols,searchcustmidcols,searchcustcols,searchcustmidcols,searchcustcols,searchcustmidcols"
 rowClasses = "searchcusttoprow"
 style="backgroundColor: '#ECF2FE';"
 >

 <rich:column>
 <a4j:commandLink ajaxSingle="true" actionListener="#{backing_CustSearchBean.sortHistoricalOpp}" styleClass="dt_small" oncomplete="alert('completed the event')" reRender = "transtable">
 <f:attribute name="sortField" value="getHistOppWO" />
 <h:outputText value="WO#" />
 </a4j:commandLink>
 </rich:column>
 <rich:column>
 <a4j:commandLink ajaxSingle="true" actionListener="#{backing_CustSearchBean.sortHistoricalOpp}" styleClass="dt_small" oncomplete="alert('completed the event')" reRender = "transtable">
 <f:attribute name="sortField" value="getHistOppStatus" />
 <h:outputText value="Opp Status"/>
 </a4j:commandLink>

 </rich:column>
......
</rich:dataTable>

As written in the code, alert in Oncomplete handler is gets invoked. Only the method bound to actionListner is not get called.
Please suggest where I can be wrong.

Thanks in advance!

Put <h:messages> component on a page , and update it for a all ajax requests :

<a4j:outputPanel ajaxRendered="true" >
 <h:messages>
</a4j:panelOutput>

Action methods can be bypassed due to validations errors.

I put h:messages but I dont get any validation errors. Can there be more reasone for this kind of behavior? Are there any alternatives?

Use please http://www.jsftutorials.net/faces-config/phaseTracker.html to check if the request was normally passed through the JSF lifecycle.
