Re: [Factor-talk] <checkboxes> parameter

[Jon H. <jon...@gm...>]

When you write a literal sequence, the contents of the sequence is not
evaluated. For example, writing { 1 2 + } results in the sequence
containing 1, and then 2, and then the word +. So the sequence you're
passing to <checkboxes> is not of the form { { string model } }, but
in the form { { string bool word } }. To force the evaluation of
litterals in sequences, you can use the literals vocab:
http://docs.factorcode.org/content/vocab-literals.html

In your simple example case, that would be:
{
   { "Checkbox" $[ f <model> ] }
}
