[richfaces-issues] [JBoss JIRA] Closed: (RF-1885) immediate="true" does not work on a4j:support tag

immediate="true" does not work on a4j:support tag ------------------------------------------------- Key: RF-1885 URL: http://jira.jboss.com/jira/browse/RF-1885 Project: RichFaces Issue Type: Bug Affects Versions: 3.1.2 Environment: mac osx 10.5.1, safari 3.0.4 Reporter: egor kolesnikov Assigned To: Mikhail Vitenkov Fix For: 3.2.0 <rich:panel> <h:inputText id="keywordInput" value="#{stopWordsManager.keyword}" required="true" requiredMessage="Please enter the Keyword"/> <h:commandButton actionListener="#{stopWordsManager.resetSearch}" value="Reset" immediate="true"/> <p><rich:message for="keywordInput"/></p> </rich:panel> <rich:dataTable id="stopWordsTable" rows="#{stopWordsList.pageSize}" value="#{stopWordsList.stopWords}" var="stopWord" rendered="#{not stopWordsList.isEmpty()}"> <h:column> <h:selectBooleanCheckbox value="#{stopWord.selected}" immediate="true"> <a4j:support event="onchange" immediate="true"/> </h:selectBooleanCheckbox> </h:column> </rich:dataTable> </h:form> </rich:panel> It is expected that "<a4j:support event="onchange" immediate="true"/>" there will be no validation and a4j will set the "selected" attribute properly, but it looks like this does not happen - validation happens and "setSelected(boolean)" method is not being called. However, using "<a4j:support event="onchange" ajaxSingle="true"/>" solves the problem, but it looks like a "hack". It is said in the RF spec: Note, that ajaxSingle="true" reduces the upcoming traffic, but does not prevent decoding other input components on the server side. Some JSF components, such as h:selectOneMenu do recognize the missing data in the request map value as a null value and try to pass the validation process with a failed result. Thus, use a4j:region to limit a part of the component tree that will be processed on the server side when it is required.
