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. One option is to do "component.setDisabled(true)" in some backing beans but turn it back on in all the others. Now, one method I read is to put that code in the backing bean's constructor, but that only works if all my beans are request-scoped, which I can't guarantee. Another option might be to use a tag attribute to make the component disable (or not render). If I could retrieve the currently selected item from my menuModel in an EL expression, then I could store the "should this field be enabled?" information in the menu item class and retrieve it at rendering time through EL. This would be ideal, because the information about whether the select box should be enabled or not naturally belongs in the description of the page, not in a random backing bean constructor. I don't know how to do it, though. ViewIdPropertyMenuModel doesn't seem to have a method that will get the current menu item. Though it does have a method to get the current viewId, so maybe I could write a method to traverse my tree of menu item backing beans and find the one with the same viewId. At this point, I'm contemplating ugly hacks. Any other ideas about how to accomplish this? Thanks Dan
