I am using an :observe\_field on a series of select elements. It is  
pretty successful. There is one bug with it that is killing me  
though. When I change the option in a select, the :with parameter is  
sent, the next element is updated, and everything is good.

Processing IpController#select\_technology (for 0.0.0.0 at 2007-09-27  
11:31:39) [POST]  
Session ID: c2e7072af4526b7b7a617e526e3d161b  
Parameters: {“ip\_info\_vw\_ring\_technology\_key”=\>“1”,  
“action”=\>“select\_technology”, “controller”=\>“ip”}  
The actual tech key is 1  
The session tech key is 1

If I change the option in the first select again, quickly (2 seconds  
later), the action sent to the controller does not contain the :with  
parameter.

Session ID: c2e7072af4526b7b7a617e526e3d161b  
Parameters: {“action”=\>“select\_technology”, “controller”=\>“ip”}  
The actual tech key is 0  
The session tech key is 0

If I wat a little longer between changing options (6-7 seconds), it  
behaves correctly. Is this a bug anyone else has seen? It is  
maddening!

Thanks for your help,
