Wolfgang, I would suggest using the trinidad dialog framework. To do this you would need to do the following:
1) create a page for your dialog. this would be like something like this: <?xml version="1.0" encoding="iso-8859-1" standalone="yes" ?> <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"; version="1.2" xmlns:f="http://java.sun.com/jsf/core"; xmlns:tr="http://myfaces.apache.org/trinidad";> <jsp:directive.page contentType="text/html;charset=utf-8"/> <f:view> <tr:document title="Save Dialog"> <f:loadBundle basename="com.somecompany.project.view.resources.messages" var="bundle"/> <tr:form> <tr:panelPage> <f:facet name="branding"> <tr:outputLabel value="Save Dialog"/> </f:facet> <tr:panelFormLayout rows="3" > <tr:panelBox inlineStyle="width:500px;"> <tr:outputText value="#{bundle.save_msg}"/> </tr:panelBox> <tr:panelHorizontalLayout> <tr:commandButton text="Ok" action="#{saveDialogBacking.handleDialogOkButton}"/> <tr:commandButton text="Cancel" immediate="true" action="#{saveDialogBacking.handleDialogCancelButton}"/> </tr:panelHorizontalLayout> </tr:panelFormLayout> </tr:panelPage> </tr:form> </tr:document> </f:view> </jsp:root> 2) in faces config put a navigation case in for the dialog that has a from-outcome that starts with "dialog: <navigation-case> <from-outcome>dialog:saveDialog</from-outcome> <to-view-id>/dialogs/common/saveDialog.jspx</to-view-id> </navigation-case> 3) add the useWindow="true" and the returnListener attributes to the commandButton tag. 4) add this to your web.xml to enable lightweight dialogs <context-param> <param-name>org.apache.myfaces.trinidad.ENABLE_LIGHTWEIGHT_DIALOGS</param-name> <param-value>true</param-value> </context-param> 5) add an action attribute with a method binding to an action handler method. This method is going to return dialog:saveDialog" if the user has made any changes or the next view id if they haven't. 6) Add a dialog return listener to your backing bean /** * cancelDialogListener - a returnListener for the save changes * dialog. * * @param evt The ReturnEvent from the dialog. */ public void cancelDialogListener(ReturnEvent evt) { String returnedValue = (String)evt.getReturnValue(); if ("Ok".equals(returnedValue)) { saveChanges(); } /* navigate user to new viewId */ FacesContext context = FacesContext.getCurrentInstance(); context.getApplication().getNavigationHandler().handleNavigation(context, null, "the_next_view_id"); } 7) The SaveDialogBacking class just needs these two methods: /** * handleDialogOkButton - controls page navigation from dialog * when user click OK button. * @return null */ public String handleDialogOkButton() { RequestContext.getCurrentInstance().returnFromDialog("Ok", null); return null; } /** * handleDialogCancelButton - controls page navigation from dialog * when user clicks CANCEL button * @return null */ public String handleDialogCancelButton() { RequestContext.getCurrentInstance().returnFromDialog("Cancel", null); return null; } I think this is all you need to do. Let me know if you have any questions. -Richard On 5/2/08, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > > > Hi, > > Wondering if sth. like > > <tr:commandButton > rendered="#{identity.hasPrivilegeUpdate()}" > id="vehicleSpeichern" > actionListener="#{TC1302.exit}" > onclick="return > confirm('#{messages['ask_if_really_save']}')" /> > > would be possible with panelPopup.
