Hello,
I repeatedly get the following error: t has no properties (got the info
using Firebug with Firefox)
It bombs on line 586 of wicket-ajax.js:
if (t.readyState == 4)
Looks like t which is set to this.transport is null. There are many
situations where this happens in my application. One instance of this is
where I have two dropdowns, the first dropdown has an onchange event where
it updates the second dropdown. If the second dropdown yields nothing in
the list (except Choose One), it results in this error. Also, if you select
Choose One in the first dropdown it yields this error. Another instance
when I get this error is when I perform an AJAX request, then make some
other normal request, then click the back button and attempt to make another
AJAX request. There are other cases where I seem to be getting this error as
well. I think it only started happening when I upgraded to 1.2.3.
Any thoughts?
