debugging bean populate

2003-06-09 Thread Nathan Coast 
Hi,

I'm getting an IllegalArgumentException presumably due to trying to 
populate a field of a form with the wrong datatype.  I can't see where 
I'm going wrong.  Is there a simple way to turn on debugging for the 
BeanUtils.populate code to see which attribute is failing?

thanks
Nathan
