Thanks a lot! Is there going to be a book? This is great information that I'm afraid no one knows about because there isn't a good reference beside the Javadocs. Now that I think about it, the skinning system is there too. Complex, powerful, and spotty documentation.
I'd love to see a book about ADF or Trinidad. And I thought I read that there would be one... -----Original Message----- From: Simon Lessard [mailto:[EMAIL PROTECTED] Sent: Thursday, September 14, 2006 10:52 AM To: [email protected] Subject: Re: Can I retrieve the currently selected menu item from a menuModel? Hello, You can use: // Backup the state Object oldKey = model.getRowKey(); // Get the selected key Object focusKey = model.getFocusRowKey(); // Get the selected data model.setRowKey(focusKey); Object data = model.getRowData(); // Restore the model's state model.setRowKey(oldKey); Regards, ~ Simon On 9/14/06, Daniel Hannum <[EMAIL PROTECTED]> wrote: > > My question is one solution to a problem that I'm facing: > > > > Basically, I have a selectOneChoice in a facelets template, shared by > all pages, but I'd like to disable it on some pages.
