Mmm... I can't understand what is happening. I've just tried to make a resizeable map
with no CSS pure JavaScript only and it also produces the same bug! The thing I can't
understand is I already have a production site with resizeable map and it works OK!
Looks like I'm doing something wrong, but I can't see what it is...
I would very appreciate any feedback. Also going to post to GMaps group.
Sorry if it is my fault.
Sincerely yours...

The problem seems to occurs deep inside a code, that does some job with map type
controls. Also, if I comment out map.setUIToDefault() method call, it works fine and
no error occurs.
I'll try to reproduce the problem with different map controls and will write results
here later.

Yep, it looks like the bug is because of old friend ;) map.setUIToDefault().

Changed that call to a set of equal (?) calls:

map.addMapType(G_PHYSICAL_MAP);        
map.addControl(new GLargeMapControl3D());
map.addControl(new GScaleControl());
map.addControl(new GMapTypeControl());

and it works fine now.

Thanks for updating this issue with your progress.

So it looks like the bug occurs when:
- using IE6, IE7, IE8
- setting map dimensions using relative sizes
- calling GMap2.setUIToDefault()

Is that correct?


I reproduced the bug on IE6, and I also noticed this error is thrown even when
GMap2.checkResize() isn't called.

This looks like a regression bug from 2.147 and 2.148 since the error doesn't exist
on 2.147.

Thanks for reporting this.  Can you confirm you're seeing the same?

Yes, the bug occurs in IE6-7-8

Looks like the map dimenstions doesn't matter - I tried with relative sizes at first,
but after that I created purely JavaScript resize function to resize map canvas to
fixed size and it still produced the error.

The bug is directly related to GMap2.setUIToDefault(). If one replaces the call to
GMap2.setUIToDefault() to equvalent code, the error disappears. More exactly, the bug
appears somewhere deep in map type controls positioning code. I don't know why this
code works on a map click, but when I launch script debugger on the error, it shows a
code that plays with map type control's DIV and breaks on accessing its offsetTop
property.


Glad to be helpful :) I like Google Maps very much, thanks for your work! :)

Issue 1556 has been merged into this issue.

Issue 1556 is also fixed, but it's not the same bug as this one, because 1556 happens on Firefox while 1479 is 
an IE-only problem.
