[Seaside] Re: Setting checkboxes using JQuery

[Lukas Renggli]

Have a look at the JQuery documentation:

    http://docs.jquery.com/Attributes/val#val.28.C2.A0val_.29_2

I agree that the way the #value: thing works is a bit strange (you
have to assign IDs to the checkbox and specify those in the argument).
There is nothing we can do about that in Seaside though, report it in
the JQuery bug tracker if you think that this should be changed.

I suggest to use #attributeAt:put:. This works without problems and is
relatively simple:

   (html jQuery: ':checkbox') attributeAt: 'checkbox' put: true

Cheers,
Lukas
