Nope. There was not another chained exception at all. This is simply why
it takes me 2 days to discover the error!

After posting the mail and rewriting the getList() method to "copy" the
data from the returned Query collection to a new bean then the works fine.

I also did another trick:

If I used "other" bean for it works too. But I have a
very hard head and I wanted to save back to the same bean. This is why I
debugged and tried like crazy. :-D

Well, another interesting stuff is that I discovered that JXPath first
call the method "addArea" with a empty bean and then fill the bean. It is
interesting to me :-)
