Subject Re: HashMap of Vectors and Indexed Properies
Date Sun, 04 Apr 2004 21:02:33 GMT
Just realized I missprinted something, my code now looks like:

<html:text name="myForm" property="address(texas).element[0].street1"/>
<html:text name="myForm" property="address(texas).getElement[0].street1"/>
as the "get" is not needed.

But again, let me know if anyone has any ideas on how I can get this working without subclassing

 If the
