Currently, the pointers you get after a user clicks a row are "view id", "component id", "row id" (where "row id" is actually...]]> Sun, 11 Feb 2007 15:15:04 -0500 Sun, 11 Feb 2007 15:15:04 -0500 Sun, 11 Feb 2007 15:15:04 -0500 Feb 11, 2007 Steven Murray 2 Re: Understanding the problem - JSF id's http://www.theserverside.com/discussions/thread.tss?thread_id=44186 ...]]> Sat, 10 Feb 2007 04:54:02 -0500 Sat, 10 Feb 2007 04:54:02 -0500 Sat, 10 Feb 2007 04:54:02 -0500 Feb 10, 2007 augustientje bloem 3 Re: There are 2 models http://www.theserverside.com/discussions/thread.tss?thread_id=44186 There's a model of the view (view-state), is it a web view or a swing app, and a business model.

These sequential numbers we keep refering to are XML id's. They are not intended to be used as dataset keys....]]> Fri, 09 Feb 2007 23:02:25 -0500 Fri, 09 Feb 2007 23:02:25 -0500 Fri, 09 Feb 2007 23:02:25 -0500 Feb 9, 2007 Steven Murray 4 Re: Understanding the problem http://www.theserverside.com/discussions/thread.tss?thread_id=44186 I absolutely agree that the scenerio you present is accurate.
