I must be going crazy. On the 5.0.18 docs for component rendering<http://tapestry.apache.org/tapestry5/guide/rendering.html>, it clearly states that in setupRender(), "This is a good place to read component parameters and use them to set temporary instance variables.".
So I did exactly that. I made a Foo page (with simple tml), with an embedded Bar component (with simple tml) that takes a required parameter called barParam of type String. I bound barParam in Foo's setupRender to "someString". In Bar's *setupRender*(), I set a breakpoint, and voila, barParam is null. Amazingly, I set a breakpoint in *beginRender*(), and barParam is properly set to "someString". Am I missing something??? Second question -- if an embedded component handles an event, i.e. onActionFromHello, it appears that bound parameters from initial page render are lost on subsequent calls straight to the url, i.e http://example.com/foo.bar:hello (as this would happen in AJAX). As I understand it, the only way to keep this persistent between subsequent AJAX calls would be using @Persist? Third question: event methods can be placed on pages, not just components, right? i.e if on page Foo i want to bind to the event Hello, i just add "void onActionFromHello() { //blah blah }" and I should be able to trigger that event by hitting http://example.com/foo:hello , right? That doesnt seem to work, it complains with "Request event 'hello' (on component foo) was not handled; you must provide a matching event handler method in the component or in one of its containers."... I don't have to do anything else, right? Thanks, Jason
