Problems with Ajax requests within a a4j:repeat loop ---------------------------------------------------- Key: RF-1341 URL: http://jira.jboss.com/jira/browse/RF-1341 Project: RichFaces Issue Type: Bug Affects Versions: 3.1.3 Environment: MyFaces, Richfaces 3.1.3 snapshot Reporter: Peter Mahoney I have come across two problems following a change to put some fields in an a4j:repeat loop. The backing beans have not changed. This is the code: <a4j:repeat id="termClauses" value="#{collectionSearchHandler.termClauses}" var="clause"> <a4j:region id="vocabularyFilterRegion"> <h:selectOneMenu id="vocabularyFilter" value="#{clause.vocabulary}"> <a4j:support id="vocabularyAjaxSupport" event="onchange" reRender="termFilterPanel" ajaxSingle="true" /> <f:selectItem itemValue="#{collectionSearchHandler.blankVocabulary}" itemLabel="#{msgs.quizFirstVocabularySelectItemDescription}" /> <f:selectItems value="#{collectionSearchHandler.vocabularyFilterItems}" /> </h:selectOneMenu> <a4j:status startText="#{msgs.quizTermSearchInProgressMessage}" /> </a4j:region> <a4j:region id="termFilterRegion"> <a4j:outputPanel id="termFilterPanel"> <h:panelGroup rendered="#{clause.hasVocabulary}"> <ul style="list-style-type:none; margin:0px;"> <a4j:repeat id="termFilters" value="#{clause.termFilters}" var="termFilter" rowKeyVar="idx"> <li> <h:selectOneMenu id="termFilter" value="#{termFilter.term}" converter="com.dbplc.quiz.Term" style="width:100%"> <a4j:support id="termAjaxSupport" event="onchange" reRender="termFilterPanel,qbankSearchResultsPanel" ajaxSingle="true" actionListener="#{collectionSearchHandler.searchPerformed}" /> <f:selectItem itemValue="#{collectionSearchHandler.blankTerm}" itemLabel="#{msgs.quizFirstTermSelectItemDescription}" /> <f:selectItems value="#{clause.termFilterItemMap[idx]}" /> </h:selectOneMenu> <h:commandButton actionListener="#{collectionSearchHandler.searchPerformed}" /> </li> </a4j:repeat> </ul> </h:panelGroup> </a4j:outputPanel> <rich:messages /> </a4j:region> </a4j:repeat> Firstly I get the following error when the form is submitted by changing the "VocabularyFilter" value: /questionsearch.xhtml @25,77 value="#{clause.vocabulary}": Target Unreachable, identifier 'clause' resolved to null If I add an onchange="this.form.submit()" to the field, to bypass the Ajax, it works fine. So, with the above workaround, I then get the problem that the collectionSearchHandler.searchPerformed() method (referenced by the a4j:support tag) is only called every second form submit. This worked without problems before adding the outer a4j:repeat. Using the commandButton to submit the form works every time. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
