Javascript error conflict between separate classes

[xhunter]

I have been working on this for some time and I came to the conclusion that I have no idea what is the problem,

I am sure it should be something simple that I am overlooking, but I can't figure where,

I have written some classes to load the google map using google map API and a grid using extjs,

here is the page :
http://tinyurl.com/5clr49

and here is the classes:
http://tinyurl.com/6ryng5

no problem here, everything works fine and no issues,

first I will explain what is going on:

variables are set in "pxxx_map_s et" and "pxxx_grid_ set" (xxx=228),

after the calss object is created :

 var pxxx_Google_Grid = new pxxx_Google_Grid_UI; 
 var pxxx_Google_Map = new pxxx_Google_Map_UI;

those variables are sent to this object with "init" function :

 Ext.onReady(function(){pxxx_Google_Grid.init(pxxx_grid_set,pxxx_Google_Map);}, pxxx_Google_Grid, true);
 window.setTimeout(function(e) {pxxx_Google_Map.init(pxxx_map_set,pxxx_Google_Grid)},'0');

no problem here,

now here is another clone with different "xxx" (2000) name:
http://tinyurl.com/59ghs3

the script is exactly the same,

that one also works fine,

now if you put them together :
http://tinyurl.com/6zby37

errors start appearing:

v is undefined

at first I had the two of the pages create an instance of the same class name and I thought maybe there is a conflict,
but later on when I gave each of the page it's own separate class:

first page (xxx=228):
pxxx_Google_Map _UI()
and
pxxx_Google_Gri d_UI ()

and 2nd page (xxx=2000):
pxxx_Google_Map _UI()
and
pxxx_Google_Gri d_UI ()

Now I can not understand why these 2 are conflicting.

ps.
"v" is set through "init" from "pxxx_map_set.v "

I just cant figure out where is my mistake,

There doesn't seem to be any errors, so I guess this has been solved. Does make sense, I suppose, when you consider it's been a month since you posted ;)
