Issue with start_date and end_date when dragging a master ev

When dragging and dropping standalone events or child events no problems,
but when dragging and dropping a master event the following javascript error occurrs:

[code]Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.2; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727)
Timestamp: Thu, 27 Jan 2011 11:55:23 UTC

Message: ‘start_date’ is null or not an object
Line: 22
Char: 3
Code: 0
URI: …xmlCalendar/codebase/ext/ext_limit.js

[/code]

as you may notice I’m using the expanded source version of limit file to troubleshoot.

Using Fiddler2, I can see that in these particular circumstances, the form data sent to my processor contains:

NaN/NaN/NaN NaN:NaN

in both start_date and end_date

Full request code for last stage of drag and drop:

1296126841461_start_date=NaN/NaN/NaN NaN:NaN 1296126841461_end_date=NaN/NaN/NaN NaN:NaN 1296126841461_rec_type= 1296126841461_rec_pattern= 1296126841461_event_pid=7603 1296126841461_event_length=1297234800 1296126841461_id=1296126841461 1296126841461_text= 1296126841461_!nativeeditor_status=inserted

Any ideas? This is one of the last hurdles I have to get over…

still no luck this end…
