Hi. I was hoping someone could shed some light on a problem I'm
seeing w/UI 1.7.2 that isn't present w/UI 1.5.3.
I've got some mildly complicated code (or I'd post the whole thing
here) that relies on draggable and droppable. It works fine in
1.2.6/1.5.3, but throws an error under 1.3.2/1.7.2 inside of the
following code (which is part of jQuery UI):
$.ui.plugin.add("draggable", "cursor", {
start: function(event, ui) {
var t = $('body'), o = $(this).data('draggable').options;
if (t.css("cursor")) o._cursor = t.css("cursor");
t.css("cursor", o.cursor);
},
stop: function(event, ui) {
var o = $(this).data('draggable').options;
<===== $(this).data("draggable") is undefined
if (o._cursor) $('body').css("cursor", o._cursor);
}
});
The code in 1.7.2 apparently expects that the draggable element has
some associated data but it seems not to be there. Again, this isn't
a problem in 1.5.3.
The logic in question is using draggable and droppable to implement
dragging grid (table) columns around to reorder the columns. When a
column is dropped, it blows away the elements in the table's thead and
tbody and
regenerates the HTML for them using the new column sequence.
Stepping through the code, I can see that my logic that dumps and re-
renders the HTML occurs before the above problem line is hit. Which I
guess might be the problem. But then why isn't it a problem in 1.5.3?
I'm kind of stumbling around a bit on this so any thoughts as to what
might be the cause/solution for this would be very much appreciated.
Thanks,
Andy
