[richfaces-issues] [JBoss JIRA] (RF-11054) Dynamically created tabs within tabPanel causes NPE in getActiveItem()

[ https://issues.jboss.org/browse/RF-11054?page=com.atlassian.jira.plugin.s... ] Jean ANDRE commented on RF-11054: --------------------------------- Finally we get success in using the following code. {code} <h:graphicImage value="/images/closeButton.png" styleClass="closeButton" onclick="closeTab('#{tab.id}');event.stopPropagation();" immediate="true" /> {code} {code} <!-- --> <!-- CLOSE TAB --> <!-- --> <a4j:jsFunction id="closeTab" name="closeTab" action="#{desktopTabController.doCloseTab}" render="menu-opened-tabs,desktopTabPanel"> <a4j:param name="tabId" assignTo="#{desktopTabController.closeTabId}" /> </a4j:jsFunction> {code} The function event.stopPropagation() instead of Event.stop(event). The NPE is a contextual bug : it may depend on : - Having or not having set the activeItem - We have also return an Collections.unmodifiableCollection(xxx) of our dynamic tabs. - Event order ?? RichFaces should guide the users on how build robust dynamic tabs that supports also dynamic close/deletion. What are the best practices and what are the buggy scenarios. There is different ways to build dynamic tabs, some are better than other, some are better suitable for a specific situation than other and etc. It would be good that richfaces give us the closeTab as a built-in feature and allow us to decide to close or not closing the tab based on the user context (I mean, user is editing some field, do we need to cancel the modification...) -- This message is automatically generated by JIRA.
