[ https://issues.jboss.org/browse/RF-13066?page=com.atlassian.jira.plugin.s... ] Andrea Martino commented on RF-13066: ------------------------------------- I have debugged the code and at least I understand why the <a4j:ajax /> behavior is not executed. When clicking on the radiobutton the component that is executed has type org.apache.myfaces.custom.radio.HtmlRadio (coming from tomahawk). Since this class does not implement ClientBehaviorHolder, org.richfaces.context.RenderComponentCallback#findBehavior(UIComponent) returns null and no update is performed. In order to work with "spread" layout, org.apache.myfaces.custom.radio.HtmlRadio should probably implement ClientBehaviorHolder and delegate the calls to the "for" radio button. the org.apache.myfaces.custom.radio.HtmlRadio should be extended as following: {code} /** * Delegating ClientBehaviorHolder to "for" UIComponent */ @Override public Map<String, List<ClientBehavior>> getClientBehaviors() { UIComponent uiSelectOne = findComponent(getFor()); if (uiSelectOne instanceof ClientBehaviorHolder) { ClientBehaviorHolder clientBehaviorHolder = (ClientBehaviorHolder) uiSelectOne; return clientBehaviorHolder.getClientBehaviors(); } } {code} I will create a bug for Tomahawk and see if this could be implemented on their side. -- This message is automatically generated by JIRA.
