Well i guess the onPassivate-method isn't entirely out of the question since it gives a central place to handle this on the page-level as well. The tagging-variant seems nicer though. I thought i read somewhere in the documentation that a 'client-side persistence strategy' was on the horizon, which would include 'automagically' inserting persistent fields into the url. I can't find anymore where i've read it though.
Since we're talking about updating / changing the url, in a somehwat related post i asked about possibilities for rewriting the url. (I havn't found time to try to resolve this) http://www.nabble.com/url-rewriting-in-Tapestry-5-tf4496726.html#a12823397 from that post: For example I want a Venue bean with name venueX and id=123 to show up as: http://test.com/venue/countryname/cityname/venux/123 Notice the countryname and cityname, which aren't fields of the Venue-page but are derived from the association venue-page--> venue--> city --> country. I think adapting the onPassivate-method for inserting these values into the url and onActivate() for only parsing the necessary fields from this url is all that is needed to get this to work, is this correct? btw: a Url-rwrite filtr for this won't work because i also want to have the translation the other way around.: not only from nice --> tapestry internal but also from tapestry internal --> nice. Url-rewrite only gives me the former. Later on i would like to strip the first /venue/ --> http://test.com/venue/countryname/cityname/venux/123 would become http://test.com/countryname/cityname/venux/123. This becomes harder, because tapestry now doesn't know anymore to which page to redirect. out-of-the-box it starts searching for a page with <countryname>. I guess for this I have to dig a little deeper. Hmm, in hindsight i believe this isn't at all a coherent post, with almost no question or conclusion to be found... consider this a kind of braindump ;-) cheers, Geert-Jan Josh Canfield-2 wrote: > > Ok, and you want to do this without implementing a passivate method on > page > B... > > That doesn't seem like a trivial problem to solve, especially in a safe > and > general way.
