Hi,

as to 1) I guess you used a checkbox to represent yor boolean=20
property?? If so, those beasts are a little nasty to handle.
If you uncheck a checkbox in a HTML from, it means that the value will=20=

not be posted to the recieving action at all!

So you need to check if the variable is posted at all, if not, you need=20=

to set the boolean property to 0 by yourself.

There are ways around this in your form, but this might be the=20
solution...

Cheers
Jochen
