settings values for a property that has one lower case character at the beginning

The reason (as far as I found out) is as follows:

ok, you are right
i looked it up in the java beans 1.01 spec
in chapter 8.8 it says:
"...we normally convert the first character to lower case. However to support ... use of all
upper case ...if first two characters ... are upper case ... leave it alone."
this behaviour was a bit confusing, since normally all variables start with lower case.
also no exception is thrown by setProperty(...) nor at least a warning that the method is not available. it just doesn't work.

OK its been a while since I looked at the java beans spec - my first thought is you should be using "XValue" as the property name instead of "xValue".
