I am trying to use Ajax with a command link to update a dialog. Te form doesn't have any id, I am not able to run this page also, it says component with "dialog" not found/doesn't exist
<h:form>
<p:tabView id="tabView">
<p:tab id="tab1" title="Tab 1">
<h:panelGrid columns="1" cellpadding="10">
<h:dataTable value="#{testBean.dataList}" var="data">
<h:column>
<h:outputText value="#{data}" />
</h:column>
<h:column>
<p:commandLink action="#{testBean.loadCommentHistory(data)}"
update="dialog" oncomplete="dlg.show()">
<h:graphicImage url="resources/theme1/images/comments.gif"
styleClass="basicImageStyle" />
</p:commandLink>
</h:column>
</h:dataTable>
<p:dialog id="dialog" header="Dynamic Dialog" widgetVar="dlg">
<h:outputText value="#{testBean.commentHistory}" />
</p:dialog>
</h:panelGrid>
</p:tab>
</p:tabView>
</h:form>
