I’ve a tomcat application with jsf 1.1

Case:
My application has a jsp (let name it /create.jsp) that contains a form to create a Business Object (imagine type person). One of the attributes of this Business Object is a relation to itself (the BO person, has an attribute father, that is also of type person). For this porpose, in the jsp, I have a selectable, and a button. The button enables to create new Business Object (in this case, a person). Therefore, the jsp show in the popup is the same that the one shown in the main window

Problem:
I’m facing wrong behaviours in the main window.

Cause:
I’ve studied the case, and the reason of the problem is the ids of the views stored in the server. When the users requires a new page, the server creates a view (ViewRoot) and stores it at the session. The jsp path is used as the id of the View. When the user submits a form, it will rehuse the same view stored in the session.
The problem in my case is that the popup ViewRoot, and the main window ViewRoot share the same id. So when the main window is shown, its viewRoot will be stored (let say id /create.jsp), but, when the popup is shown, its viewRoot will overwrite the main one in session. After closing the popup, the user will try to submit the main page, but in the server, there is no such a ViewRoot.

Possible Solution:
I’ve been thinking on changing the ViewRoot id creation, but I thing that this is not feasible (at least if I don’t modify the jsf library).

—OLD TEXT—
I have a jsp with a form (let name it /create.jsp), that opens a popup window. This popup will also use /create.jsp .
Due to that JSF view-id, is fomed by the jsp path, both pages will share same id. So when the popup is displayed, the view stored in the session for the main page is overwritten by the new one. Because of this, the application is not working properly.

Is there any way to change the ids of the views? anyone has any solution?

Thanks

    My final solution is the following:

    1. Create a jsp name popup_create.jsp, that only contains an inlcude to the create.jsp
    2. Duplicate create.jsp entry in facesconfig with popup_create.jsp
    3. Create a ViewHandler (add it in config) with an extension of ViewHandlerImpl, where createView & restoreView methods are ovewritten, so that the viewId, in case that is create.jsp, and we are in a popup, it will modify the viewId to poup_create.jsp.

    As I think this may be done in a more elegant way, it is the only way I’ve found.
