Strip header contributors from Ajax response.
I have a component which contributes Js headers. This component is also
rendered by AjaxRequestTarget. The problem is that when rendering ajax
response the Js codes too are getting rendered. These Js codes were already
contributed when this component first rendered (in non-Ajax mode).
To fix this what I initially did was that in the onBeforeRender method of
the component I was checking if the response NOT isAjax then add the header
contributors, else, remove them. This was working fine, but problem is if I
want to implement this is other components I would have to copy n paste the
codes. So I decided to implement a behavior. I added all the header
contributors to that behavior and it was supposed to do the job of adding n
removing the header contributors. But we can't modify hierarchy from
beforeRender of behavior so I am now stuck. Furthermore, this approach is
not capable of removing JS contributed by super calsses of the componenet.
Please suggest.
Thanks and regards,

Hi Igor,
It is not that duplicates items are getting rendered. What I want is that
the Js should be rendered ONLY when rendering in non-Ajax mode. In Ajax mode
the Js code should be stripped out. As these Js codes are not executed when
in Ajax response so it doesn't make sense to render them there. This
unnecessarily bloats the response.

you use iheadercontributor to write out the url to the resourse, which
i think will point to the javascriptpackageresource.

That's a good point. :)
BTW if i implement my own IHeaderContributor how will take advantage of
wicket's js code stripper and compressor provided by
JavascriptPackageResource?

In terms of hosting it is measurable. Each byte of request for a million
hit site is 10Mbit of line cost.
That being said most latency is about connections and not amount of data.
At least in terms of speed up I would look first at reducing things like
frames, then resources, then size.
Inlined ajax, yeah /shrug with the caveat for hosting solutions.

amd this bloating has caused a noticeable slowdown in your site's
response times? how much latency is it adding to the response?
that said, you can always output it using iheaderresponsecontributor
and add an check if you are inside ajax or not using request.isajax()

@Igor
I have a very tight budget so the resources are pretty limited, so I need to
save the bandwidth wherever possible. BTW I didn't find any class -

amd this bloating has caused a noticeable slowdown in your site's
response times? how much latency is it adding to the response?
that said, you can always output it using iheaderresponsecontributor
and add an check if you are inside ajax or not using request.isajax()

Re: Strip header contributors from Ajax response.

Hi Igor,
It is not that duplicates items are getting rendered. What I want is that
the Js should be rendered ONLY when rendering in non-Ajax mode. In Ajax mode
the Js code should be stripped out. As these Js codes are not executed when
in Ajax response so it doesn't make sense to render them there. This
unnecessarily bloats the response.

Re: Strip header contributors from Ajax response.

wicket will filter duplicate contributions for you and even though
they are rendered they are not executed. if you are writing out
javascript directly you can set a string id which uniquely identifies
the contribution and wicket will also filter by that.

Hi All,
Thanks for all the responses. I got this solved by making my behavior extend
AbstractHeaderContributor. In its getHeaderContributors() I return the list
of headers only if response is not ajax. In case of ajax I simply return
null.

Another more complicated way seems to be using SharedResources and
DynamicWebResources, an example of this, you can find it on
"UploadStatusResource" class of
wicket.extensions.ajax.markup.html.form.upload package

Good Afternoon,
I've working on this theme, and I found a solution to avoid the strip of our
resources.
On the Ajax Behavior, we put this lines:
ResourceStreamRequestTarget targetRes = new ResourceStreamRequestTarget( new
PackageResourceStream(MyScopeClass.class,"resources/myJS.js"));
targetRes.setFileName("MyJS.js");
RequestCycle.get().setRequestTarget(targetRes);
And, this way, we can still using our resources redered with the
HeadersConstriburtors
