problem for from constraint

[sourir]

i have rule like this:
when { n1: Number from [1,2,3,4,5]; }

but i got :
[ Number, "n", "true" ]
in js file.

Is it my fault?
Thanks in advance!

No, what you are seeing is the default constraint which is, the boolean constant true. It's important to remember that 'from' is providing a substitute for facts in working memory. The from modifier is not a constraint, just a source of data. So what you really have is: n1 : Number; with a from modifier to provide the number fact(s).
