Re: how to stopInterval which was created by JSObject>>interval:

JSObject has #assignTo: which you can use to assign the interval id returned
by the setInterval() js function to a js var name in the browser.  So in
your case I might try 



(((html jQuery id: anId) load
html: [ :r |
...show the report file... ];
interval: 2 seconds) assignTo: 'interval',anId



Then later you can clear the interval.


Another strategy is to use your polling code to set a #timeout: rather than
the #interval:.  So the polling code checks to see if the report is ready,
if not it sets another timeout to check again in two seconds. 
 When the report is ready, it returns the report.  In that way the
interval/timeout mess cleans up after itself.
