actionListener on a4j:commandLink not called
Using a binding, I am dynamically building a set of panelBarItems inside of a panelBar. Inside of each panelBar I have a dataTable with a column of a4j:commandLink "Add" links. Visually this is being built properly, but when I click on my any of my "Add" links nothing happens. By nothing I mean my method does not get called and I receive no errors. The add link is mapped an actionEvent called "addArticle", but it never gets called. I'm stuck and am looking for some assistance.
<a4j:region>
<rich:panelBar id="availableArticlesPanelBar" height="100%" width="200" binding="#{surveyCtrl.panelBar}" />
</a4j:region>
