i recently had what i believe to be a strange occurrence while writing a very simple app. 

pay attention to destaddress property of Formmail...

this gave me a error
Exception during request processing: javax.servlet.ServletException: /FormmailList.xhtml: Bean: com.foo.Formmail, property: destaddress
......
after banging my head against the table for a while,, i figured out that Seam had changed the property name from destaddress to destAddress.

WHY?? 

I went back and change the name of the column in my db,, then alter my code a little... none of the weird junk,,, just with destaddress-->destAddress.

explanation anyone???

what don't i understand??
i mean randomly mapping characters in a variable name string to upper case makes the mapping a little difficult if you catch my drift.
