Ajax - on Submit: "Requerst failed - status=500"
Hi
I updateted my form with ajax. Now Iam getting a server error like described

Re: Ajax - on Submit: "Requerst failed - status=500"
Posted by ZongoZongo <nr...@gmx.net>.
I have a complex cform with tabs und repeaters. When you use ajax, only the
form is relaoded after something is changed instead of the whole site.
The problem arises because I use tabs und an aggregator to build the site.
So I have to place the stylesheet, that transforms the form inside the
aggregator after the aggregation, because the code of the tabs needs the
<head/> that is placed after the aggregation (finalize.xsl). The ajax
selector has to be placed after the stylesheet of formtransformation and in
this way inside the aggregator.
I dont know which part causes the problem exactly. The form is displayed
correctly. I can also work with the form. But when I hit the submitbutton
the error pops up.
I hope its not too confusing ;-)

Hi Niclas,
I've been reading your email, but it's not 100% clear with what you mean
with using Ajax with an aggregator.
What kind of ajax logic is inside the aggregator? What part in your
aggregate is causing this problem?
Kind regards,
Jeroen Reijn

I found the problem, but dont know how to solve it. The problem is the
location of the ajax-logic inside the aggregator. If its located inside a
pipeline everything works fine. Sadly I have to put the formprocessing after
the aggregation, because the tabs inside the form need, the tag <head/>,
that is created after the aggregation through finalize.xsl.
Maybe somebody has an idea for a workaround ;-)
