Adam, thanks for the quick reply. I've got quite a lot of similar pages to create using tabbedPanels, so I'd like to make the most of the automatic validation based on the declarative page definition. After careful consideration, I've decided to go with your very last suggestion - with a slight tweak :-) I plan to track which tabs have been visited, but leave the button always enabled. When the button is pushed, the action will first perform a check that all necessary tabs have been visited, and if not, disclose the next required tab as appropriate. If the check passes, then the normal button action will be performed. I'll be relying on the standard behaviour of not letting the user get out of the current tab unless it's valid - so I need to ensure that no "immediate" actions switch away from the current tab. Additionally, I expect to use bean-level validation for cross-field validation where the fields are on different tabs. Many thanks for your help. Regards, Peter.

[Trinidad] panelTabbed - validation of unvisited tabs
I have a form containing various input fields followed by a panelTabbed, and lastly an OK commandButton. The panelTabbed contains some showDetailItem children, which have various input fields, some of which have required=true. The users may visit the tabs as they see fit, and then press the OK button, and I need each showDetailItem child to be valid as a precondition for the button action. However if a showDetailItem is not disclosed it will not validate its children. So if the user doesn't happen to visit every tab, the unvisited tabs may not be valid, but the validation phase passes, and the commandButton's action method is invoked. This behaviour seems wrong to me, as I would have expected that all rendered=true fields inside a form should be valid before the form is considered valid.
