I have a multipage containing several IFrames and one of the Iframes have to refresh another one. So I cause a postback using this snippet
(arguments.length > 1) val = arguments;
, param, val,
The param has a "rebindGrid" value (but I guess it doesn't matter).
In FF developer console I get this error
Sometimes is "l is null" rather than n, but again I guess it doesn't matter.
The relevant source code is this
So it looks like something related to resizing an object.
Any chance this gives you a hint on how to solve the issue?
