please paste actual code snippets every time when you get new problem. Maybe just errors in newest code and we can't see that just using the descriptions.

change action listener to action or define with f:actionListener tag instead of attribute. This works as designed in JSF spec. Listener from support called first and nested listener (setPropertyActionListener) called then.

a4j:support id="onRowClickEventId" event="onRowClick"

onsubmit="workflowRegResultFormSetReqFunctionId('REGISTRATION_DATATABLE_ONSELECTION');changeColor(this);getDocumentDetails('#{item.lcmsg.docId}','#{item.lcmsg.source}','#{rowKey}');eventButtons(true);"

action="#{workflowRegistrationBean.selectRow}"

reRender="searchCriteriaFourth,searchCriteriaFiveth" ajaxSingle="false" oncomplete="getTableDocidReg(#{item.lcmsg.docId},'#{item.lcmsg.source}','#{rowKey}');workflowRegResultFormSetReqFunctionId('');">

<f:setPropertyActionListener value="#{item}"

target="#{workflowRegistrationBean.selectedItem}" />

<f:setPropertyActionListener value="#{rowKey}" target="#{workflowRegistrationBean.rowSelected}" />

</a4j:support>
