</div>

I have the following observe field in one of my rhtml files:

\<%= observe\_field(“order\_plan”, :frequency =\> 0.2, :url =\> {:action =\>  
:update\_list}, :with =\> “id”) %\>

this works fine in firefox but Internet Explorer (6 and 7) causez my  
code to fail.  
For some reason when the observe\_field calls the update\_list it passes  
the value of null for id

…, “id”=\>“null”, …

Does anybody know why Internet explorer is doing this?

Thanks,  
James

the mystery continues. I got rid of the observe field and changed it to  
an onchange event in the select item but it still does the same.

Although i did notice it only returns null the first time, any further  
onchange events cause the right id to be passed.

has anybody else has a similar problem?
