wicketAjaxGet Size limt
Hi,
>From a JavaScript code (CkEditor pluin to be exact), I want to send data to
my wicket component/panel.
I traced the generated code, and it uses "wicketAjaxGet". With wicketAjaxGet
I can get in 3000+ characters on a rough.
This seems to have size limitation, whats the best way to get around that?
Additional Context
--------------------
Would like this to be as scalable as possible so I can send Contents in my
CkEditor on my Custom Ajax-Save button. Basically have created a plugin in
CkEditor and have my Ajax-Save on the Editor Toolbar (no Wicket button). I
have a Proxy link that generates the script, and then on JavaScript I simply
rip that off and do an eval (<server generated function code +
modifications). This submits back the data to the server and it all works
well. Just the size limit bothers me a bit. Have avoided using forms sicxe I
dont see a conceptual need for forms.
wicketAjaxPost or wicketSerializeForm (?)
----------------------------------------------
....Discussion sake .... (maybe not relevant)
I saw some post few months back where guy talks about wicketAjaxPost and
serializing Forms using wicketSerializeForm. But no code or context provided
so not sure how that works. plus wicketSerializeForm takes only one param
... the form element in javbscript. So how does it send data back to server?
Preferred Area of Solution
-------------------------
Note: This script can be modified @ the server in public final CharSequence
getCallbackUrl(final boolean onlyTargetActivePage) ; Looking for some server
side wizardry so I dont have to put in Hacke (replace commands in
javascript).

When using GET content is limited per browser. ie: Modern Browser set a
limit to 8K while others just 2K.
When using POST per the spec browser are mandate to set content-length
header, i have no idea what is going on your end, but definitely will
suggest to try that out on a different container such as Tomcat just to see
if this is something Jetty related.

Attila Király & jcgarciam --- Yup, thats it I guess. You guys are right (i
think)
I was just blindly hacking the urls & using the wicket functions.
I see now : function wicketAjaxPost(url, body, successHandler,
failureHandler, precondition, channel)
..and what I'm consuming is only the URL param.
Example:
I should be using the second param for POST to really take advantage.
Thank you all. Yup, it all makes sense now.

I'm seeing you request is still being sent as GET, since your parameters are
bound to the URL. If it would have been POST the content of your request
would appear below the:
Content-Length:wwww
Yor content here....
Or am i missing something.

Aren't you sending your data in the url? Even if you are using POST you can
still have some (all) data in the url as query parameters. And there are
limits for url length (both on client/browser side and server side). This
would also explain why does it depend on header buffer size as the url is
read into that buffer.

Since it was a server error, I changed the "headerBufferSize" config in Jetty
and it worked
..but then on changing Jetty Config wicketAjaxPost & wicketAjaxGet were both
working.
"headerBufferSize" uses the request header imo, so on post why do we need
the request header?
..Something does not seem right with my understanding of these functions or
perhaps how JETTY handles requests.
Its left me a little confused :(

Actually i did try that also and in the HTTP Live header plugin I can see its
getting POST'ed. yet for some reason content larger than a certain size is
not going.
I hope this is not a problem with CKEditor or Jetty (standard config)
thanks for the tip. I'll check other things to see why large size is not
working out.
If you have any suggestions, I'll followup.
