Hi Grzegorz,
after your plausible explanation could you give me one more?:
Either hitting return on the textfield or submitting via button results
in the browser sending two requests:
1st request (params):
forms_submit_id=&mytext=blass&dojo.transport=xmlhttp&cocoon-ajax=true
1st response: <bu:document
xmlns:bu='http://apache.org/cocoon/browser-update/1.0'><bu:continue/></bu:document>
2nd request (params): cocoon-ajax-continue=true
2nd response: The complete html-page
Well, the user gets an updated screen, but I'm missing the
get-data-and-change-view-behind-the-scenes-without-reloading-the-page-ajax-magic.
:-?
Thanks (again), Florian
