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.
