ajax isearch will sometimes drop a callback in Firefox.

[anonymous]

Sometimes, at least when a table is populated with more data than in the default example (try creating a table with 30 rows), an exception will be trown by Firefox because the "status" element in an nsIXMLHttpRequest is being accessed.

How to reproduce: Add a longer list of employees to the grid1 in application.lisp:

 (list employee1 employee2 employee3 employee1 employee2 ...<30 more>)

Reduce the latency to 0.1 seconds in isearch.lisp, line 31.

     (with-javascript "~
new Form.Element.DelayedObserver('~A', 0.1, function(elem, value) {~
initiateFormAction('~A', $('~A'), '~A');
});"

Install firebug, and set a brakepoint at roughly line 1114 in prototype.js

 } catch (e) {
1114 this.dispatchException(e);   <--- breakpoint on this line.
1115 }

After playing around with the isearch, you will see the following exception being thrown (really by the nearby success() function):

	[Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.status]" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: http://foo.org:8090/pub/scripts/prototype.js :: anonymous :: line 1109" data: no]

From what I understand from random readings on the web, this can be caused by reading the nxIXMLHttpRequest.status in an onError handler (which does not seem to happen in this case), or it can happen if the ajax request is being aborted.

Could be an issue with too many simultanious ajax requests? I'll take a look at this.

This is resolved because the search functionality is being removed from the grid.
