Test if ui:insert has been defined in the template client

阅读更多关于 Test if ui:insert has been defined in the template client

I am wondering if it is possible to know if ui:insert was defined in the ui:composition . I know that I can do it using separate ui:param , but just wanted to do it without in order to keep it simple and less error prone. Example : Template ... <ui:insert name="sidebar" />  <div class="#{sidebar is defined ? 'with-sidebar' : 'without-sidebar'}"> <ui:insert name="page-content" /> </div> ... Page 1 ... <ui:define name="sidebar"> sidebar content </ui:define> <ui:define name="page-content"> page content </ui:define> ...

Is there a convenient way to pass parameters to messages from resource bundle to components other than h:outputFormat ? For instance, this is legal: <h:outputFormat value="#{myBundle['parametricMessage']}"> <f:param value="#{myBundle['someParameterValue']}"/> </h:outputFormat> But I need it for a button, like this (which won't work): <h:commandButton value="#{myBundle['parametricMessage']}"> <f:param value="#{myBundle['someParameterValue']}"/> </h:commandButton> Of course, I can use link instead of button, and I can make it through a property in a managed bean, but in this question I'm seeking

<ui:debug/> tag not working in Facelets (JSF 2.0)

阅读更多关于 tag not working in Facelets (JSF 2.0)

问题 I am doing a project using JSF 2.0 and Facelets. I have read documentations that the <ui:debug/> tag gives valuable troubleshooting information upon pressing CTRL-SHIFT-D. But this never works for me. Please anyone tell me what am I missing. (I tried with various hotkeys, still no success. eg: <ui:debug hotkey="a"/> ) 回答1: Ensure that you pick a key which isn't reserved by the webbrowser itself. In case of Firefox, a good choice is x . <ui:debug hotkey="x" /> See also: how to debug JSF/EL

How do I insert a non breaking space character in JSF page like I can in HTML using ? Is there such a tag in JSF? this will work <h:outputText value=" " /> Putting the HTML number directly did the trick for me: If your using the RichFaces library you can also use the tag rich:spacer which will add an "invisible" image with a given length and height.

I am using Myfaces 2 on Facelets. I have to include a JSP page in a Facelet page. I tried using <ui:include> but it takes only XHTML pages. I also tried using <c:import> and <f:subview> but nothing worked. Googled a lot but didn't get the exact answer. How can I achieve the requirement? BalusC That's possible with a custom UIComponent . My fellow colleague has written a blog article about this a year ago: Facelets and legacy JSP .

This is expected to be a parse error that should occur during parsing of the XHTML file possibly throwing an appropriate exception. If it were to happen, absolutely nothing exceptional would be reported. No errors
