RE: Using JavaScript to reference Map or Indexed backed fields.

Technically, both of those field names are invalid HTML. I'm surprised
Struts creates input fields with invalid HTML names.
According to the specs:
	ID and NAME tokens must begin with a letter ([A-Za-z]) and 
	may be followed by any number of letters, digits ([0-9]), 
	hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). 

PHP does the same kind of thing for array form variables, and it causes a
lot of javascript pain for people.

Josh was correct, though, in how to reference the fields. I often prefer to
declare my field names at the top of the page, using syntax like this:

var myfield1 = 'myField[0]';

Then in your javascript later, you can do:

document.myForm[myfield1].value="blah";

It often makes javascript code easier to read, avoids typos in field names,
and if your fields change names later, you just make the change in a single
place.
