Thanks for the reply I found the js solution this night too, but the
delivery of messages on google groups seems to be very slow (Now 6
hours pending).
Now I have only left one little problem.
This should give me the value : "color" -> hidden(() => fp.color) %
("id" -> "color"). But it's empty and the definition of hidden allows
only () => fp.color not fp.color = _ like on text for example. May be
my scala skill is not good enough to find a solution.
Cheers
Torsten
