Matej, one of the problems is that when ajax submit happens (by pressing ajax submit button that resides in a form that resides in a ModalWindow that is put into another form) it contains no data for the components of enclosing form but the process of handling the submit handles the eclosing form and the validation fails or the values become empty. (If I remember all the details correctly - it was 3 months ago)
Another problem happens when you don't use ajax submit but regular one instead. If I'm not wrong Wicket can't find components of inner form. In case if some pieces are missed in sandwitch Form>ModalWinwod>Form the mismatch occurs immediately. Having no acces to hardcoded form element makes impossible to enhance ModalWindow as well as to implement just regular upload submit from within ModalWindow without patching .js file. If you could fix that (preventing wicket from making it a div) and make the form configurable it would be great! Concerning Tree. It is my subjective opinion. It is the API that was difficult to figure out how to employ to solve my tasks. I find the difference betwen DataTable and TreeTable APIs to be unnecessary difficulty to users. At least they are two different things that requires more time to learn and work with. And if you have a panel where you switch between table and tree you have to write an abstraction layer. Sven's TableTree just fits where it should be. I completely added it within 2 hours. TreeTable took 2 days to learn and employ. Once again, I'm subjective here. It was just my experience. My idea is that diversity is a good thing when the original component dont meet our needs makes the development more complicated. I'm aware of CSS positioning model and I have ideas to investigate. Besides there are a jQuery popup window which example is embedded into enclosing div and can be freely relocated inside the body. Anyway it is possible to do what the modal.js is doing by Wicket means and don't have a component tree mismatch with DOM.
