One solution is to have the dynamic CGI script create a page fragment (e.g. a <div> or <ul>) and load that dynamically. iUI 'page' (aka views or fragments) can be dynamically created and loaded via AJAX. > When I'm on that last, outside page, there's no way to go back to the > "Abbey Road" page, because once I've left iUI, no matter what URL I > dynamically construct for "back", going back takes me to the iUI home > "page". > There is a "fix" for this in iUI 0.30 which is currently available in an alpha version. (A beta should be available shortly. I'm also going to propose that we postpone unimplemented 0.30 features to 0.40 and try to release 0.30 before iPhoneDevCamp) To download the alpha look here: http://code.google.com/p/iui/downloads/list The fix has two limitations: 1) The "page" you want to go to must be preloaded (i.e. contained in initial DOM) 2) If the page is two steps down the hierarchy it will work, but a press of the back button will take you all the way back to home. By extending the function getPageFromLoc() you may be able to create more sophisticated behavior, but the code in 0.30 is a good start. Also see Issue #82 in the Issues DB: http://code.google.com/p/iui/issues/detail?id=82 I'm open for suggestions and/or patches on this issue. > And if the answer is that I should always stay inside iUI to preserve > the history, hierarchy etc of the interface, how do other people do > dynamic content?

From your e-mail, I would think the best solution would be to try to dynamically generate a page fragment with a deterministic id and keep it within the same HTML page. If for some reason you can't do that, take a look at iUI 0.30. -- Sean --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "iPhoneWebDev" group.
