Is there a way to get information from a component back to the page it is contained in? I would like to be able to display errors and warnings from setupRender() of a component in the layout component of the containing page. I'm able to accomplish this for errors in a component's event handlers by throwing an exception and having the page catch it using onException() but this does not seem to be an option in the render phase methods (and I wouldn't want to stop rendering the component). Environmentals do not seem to work either because the page appears to have already rendered itself by the time setupRender is called in the component. Part of the problem may be that I'd like to display the messages at the top of the page which has already been processed by the time the component is rendered. The errors/warnings are not serious enough to go to an exception page. I'd like to continue to render the component/page but just let the user know something was missing (and would prefer to have the message appear somewhere outside the component so the layout of the rest of the page looks ok).
Does anyone know of a way I can accomplish this? Should I be approaching this problem in a different way? Thanks.
