hi,
normally the form generates a service link such as:
"direct/1/FooPage/$Form"
now that you have overriden Form.getLink, it should look like this
(verify the hidden field in the source):
"partial/1/FooPage/FooPage/$Form"
the javascript now doesnt need to do anything fancy, just append the
part IDs as service parameters, like this:
values["service"] += "/" + parts.join("/");
of course I dont really know if that's how the friendly urls patch
works.. but the general objective is: 1) have PartialForm generate the
right service link to the partial service 2) have the javascript
dynamically append the Part IDs as service params before submit
hope this helps,
viktor
