Re: problem with checkbox values and map backed properties

[Cliff Lam <cl...@reinfo.com.hk>]

You can try to set a "unlicked value" in the reset function in the form.

When the click-box is clicked the unlicked value will be covered.

Hope this is useful for you. =)

RE: problem with checkbox values and map backed properties

hi,

thanks, already solved, problem is that the map is (of course) fille up
dynamically, and putting the code to reload it into the reset function is
not possible, as the list depends on one of the other properties of the
form.

now i just say "if there's no property in the map, it's unset".

kr,
guenther
