<div class="moz-cite-prefix">Hi Johan,<br>
<br>
I was referring to the timeout: parameter of $.ajax() which is not
supported by .load() (see here:
<a class="moz-txt-link-freetext" href="http://stackoverflow.com/questions/16129292/how-do-i-set-a-timeout-in-load-jquery-for-this-particular-example">http://stackoverflow.com/questions/16129292/how-do-i-set-a-timeout-in-load-jquery-for-this-particular-example</a>).<br>
<br>
But the wrapping of the load()-call within a setTimout() works
perfectly. So your suggestion of "addDecoration: (JSTimeout
duration: aDuration)" works perfectly!<br>
<br>
<br>
So you taught me at least 3 important lessons today:<br>
<br>
1. I can addLoadScript: in an ajax callback<br>
2. addDecoration: in JSObjects to wrap stuff into a function <br>
3. The handling of Ajax Callbacks on the Seaside Server blocks
"normal" callbacks (I know of no better way to name it)<br>
<br>
<br>
We now have a dashboard that reacts to clicks immediately. <br>
There is one thing with a bitter taste for now: the server side
Ajax processing is not stopped, so the background process still
burns cycles although nobody is interested in its results any
more. It should be easy to do this, because it is just a question
of terminating background processes and keep track of what
background processes are currently running for this session.
Combined with another Ajax call and a bit of bookeeping we'll be
able to save cycles should the need arise. For now we just enjoy
the improvements ;-)<br>
<br>
Thanks for great help!<br>

Hi Joachim,
<div class=""><br class="">
</div>
<div class="">I’m not really sure what “timeout” you are referring
to, but your reply makes me think of an issue (see below).</div>
<div class="">The timeout method I used in my code snippet
corresponds to JavaScript’s setTimeout function wrapped around
the ajax request. So, in that sense, any JS expression supports
that.</div>
<div class=""><br class="">
</div>
<div class="">BUT, an issue regarding the #timeout: message pops
to my mind:</div>
<div class=""><br class="">
</div>
<div class="">There are two unrelated implementations of the
#timeout: message. The one on (JSObject>>timeout:) is to
wrap a JS statement in a setTimeout function, the other one on
(JQAjaxSetup>>timeout:) is to set a timeout value for the
ajax request. Unfortunately, the latter overrides the former. I
suspect that the code I sent you hits that issue. You can solve
it by sending "addDecoration: (JSTimeout duration: aDuration)”
instead of #timeout:.</div>
<div class=""><br class="">
</div>
<div class="">I got bitten by this before. I ignored it (working
around it by using #addDecoration:). A colleague of mine got
bitten just a couple of weeks ago. I think you got bitten too
now.</div>
<div class="">I think I should no longer ignore this unpolymorphic
override anymore :/ [1]</div>

<br class="">
thanks a lot for this idea and code draft. It is of
course exactly what I need.<span
class="Apple-converted-space"> </span><br class="">
<br class="">
Given that we use that background process thing at
another place (show a progress dialog for a long running
process), it is sad but trrue I didn't think of the same
technique for this purpose. But of course this is the
perfect thing to do. Thus the Ajax's will be short
running and the browser won't wait for the data.
Definitely worth it.<br class="">
<br class="">
Once again: thanks a lot for your guidance and help! I
still hope one day I can give something back.<br

<br class="">
Maybe a drink in Prague at ESUG 2016 counts as a first
attempt? ;-)<br class="">
