What you were pointed to in the A4j forum was a link to reRender only part of your ui:repeat. If you'd just like to reRender the whole thing, I find wrapping things like this in <s:div> to be very helpful. eg. | <a:region> | <s:div id="blogEntriesDiv"> | <ui:repeat id="listt" var="listvar" value="#{NewBlogEntryComponent.blogEntry_be.tags}"> | <h:outputText value="#{listvar} "/> | <a:commandButton value="Delete" reRender="foo" action="#{NewBlogEntryComponent.remove(listvar)}"/> | <br /> | </ui:repeat> | </s:div> | <br /> | <s:decorate> | <h:selectOneMenu id="tags1" value="#{dev.nulll}" valueChangeListener="#{NewBlogEntryComponent.listener}"> | <s:selectItems var="field" label="#{field.toString}" value="#{AllTag}" noSelectionLabel="Please select : " /> | <s:convertEntity/> | <a:support event="onchange" reRender="blogEntriesDiv" bypassUpdates="true" /> | </h:selectOneMenu> | </s:decorate> | </a:region> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4056519#...
