RE: RE: Problem with

[Bieringer, Dominik]

Okay… what I have posted here is a simple example… In my application I am currently developing, there is a String property: (getContentPage()) on a session bean.   I have several pages, for example:  -> Downloads  -> Customers  -> Home  -> … etc.   If a user clicks on Downloads, setContentPage(“downloads.jsp”) is called and the next time the page is rendered, <jsp:include …../> includes downloads.jsp…   I’ve not tried using the rendered attribute, because it’s not possible in my case… But thanks for your idea.   From: CD [mailto:[EMAIL PROTECTED] Sent: Monday, September 11, 2006 15:47 To: MyFaces Discussion; [EMAIL PROTECTED] Subject: Re: RE: Problem with <jsp:include/>   Have you tried making use of the "rendered" attribute on the subview tag to determine which page to include?  I would also recommend encapsulating the logic used to determine the boolean value in the bean.   On 9/11/06, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: I can confirm - multiple jsp:include's - session scope bean - subview does not fix it. ----Ursprüngliche Nachricht---- Von: [EMAIL PROTECTED] Datum: 11.09.2006 12:16 An: "MyFaces Discussion"<users@myfaces.apache.org > Betreff: RE: Problem with <jsp:include/> I?ve tried that too, but that does not solve the problem? same results   From: CD [mailto: [EMAIL PROTECTED]] Sent: Monday, September 11, 2006 09:42 To: MyFaces Discussion Subject: Re: Problem with <jsp:include/>   subview tags go around the <jsp:include> in your page i.e. <f:subview id="subviewID">     <jsp:include page=" f.jsp"/> </f:subview> Then f.jsp just needs to contains the content you would like to render.

I am sorry for having created an JIRA issue () before asking here on the user mailing list (I've not known about this mailing list). Okay, so here is my problem:   I am having many pages, with one master page (in this example test.jsp). In my real world application, the master page is including other JSF pages. The page to include is determined by a String property of a session bean. So, when a user clicks on a link in the navigation menu, a property in a session bean is set and the next time the page is loaded, this page get's included, rendered, and sent to the client. (In my example I am including 2 different pages 0.jsp and 1.jsp depending on Math.random() to simulate what I want to do in my real world application).   This worked fine for some time, but in the last weeks I've watched some strange behavior. Some elements (like <h:outputText/>, ?) have been rendered twice, or in the wrong order, ? and sometimes there was a duplicate_id exception? So I tried to figure out what is going wrong and realized, that there is something about the <jsp:include>. If I use JSP include for one page? (for example 1.jsp) ? and in the next request I am including the same page, and in the next request the same page, and so on? everything works as expected, but when I include another page, this strange behaviour occurs?   I am not sure about what the problem is and I've read the JSF Reference implementation and I think I've done everything like described there. I've attached a very very simple example of what I am trying to do. You have to click on the button some times, until another page gets rendered, and you can see, that the BEFORE and AFTER label are positioned wrong ! (The MMMMMM label has to be between them). I've removed the libraries in my example to keep it small. I've used Sun RI because it's the same problem that I have when using MyFaces (In my real world application I am using MyFaces (And I really like it!!!)).   Okay, I hope you can help me, because I am already very frustrated?.
