hello mario, today it's my third and last try to send this answer :-/ (at the moment there is a strange situation - some of my mails are not delivered and some others are (but they were send to the same address(es) at a later point of time compared to the undelivered mails) - at the moment the web-interface of gmail is also a bit confused - mails aren't displayed correctly and so on (really strange) - so i try to answer directly to your first post - it's just a further try to resend my answer which was send before the second answer of cagatay.)
@cagatay: thank you for your answer – it was the reason why i recognized that my answer wasn't delivered (my answer included basically the same statement as yours) – with this mail i try to resend my previous mail. (*sorry* if sooner or later the two other mails will be delivered and the answer is duplicated) my previous answer: there is also a second possible solution for this problem. advantage: you don't have to walk through the component tree once more. (if i got the idea mentioned by cagatay right) disadvantage: it's maybe a bit more work than the PhaseListener approach. you can decorate all renderers and manually add your ValueChangeListener (it is real adding - no replacement). if you would like to choose this solution you are welcome to look at the implementation of jtracc (http://jtracc.org or directly at http://code.google.com/p/jtracc/source) - there i implemented such a wrapper (TranslationRendererWrapper). it's an other domain so you can ignore what's going on in this wrapper in detail (you only need the principle). in your case you have to add a ValueChangeListener manually by using code like: ( (EditableValueHolder) component ).addValueChangeListener(...) before you do that you have to check if the component is a component which implements the EditableValueHolder interface! after adding the listener you can simply delegate to the decorated renderer. regards, gerhard 2007/11/12, [EMAIL PROTECTED] <[EMAIL PROTECTED]>: > > Hello, I need to know witch data of a view is changed.
