[HtmlUnit] Re: Error using "this.form" syntax

[DEMATTEIS, M. S [AG-Contractor/1000] <mar...@mo...>]

"this.form" refers to the form property of the SELECT object in the
following HTML:
<select name="select2" onChange="doChange2(this.form);"> 
Mark

I don't understand what "this.form" is supposed to be.  "this" would be 
 a Window object in this case and Window doesn't have a "form" attribute. 
   What am I missing?
 
 Disclaimer: I've only visually checked your code - I haven't had time to 
 actually try it yet.

Fixed.  The problem was my misunderstanding of what object is currently 
in scope during the onclick handling.  Previously, the Window was always 
in scope for the various handlers (onclick, onsubmit etc).  I've changed 
it so that the appropriate control is in scope instead.
