Unable to use functions in expressions

[davidpadbury]

It's debatable whether we should be able to do this in the first place, but I found that creating functions in expressions will throw an error.

${sum(records, function(r) { return r.value; })}

The above produces the error "Uncaught SyntaxError: Unexpected token )". See this issue reproduced at http://jsfiddle.net/VPvDG/.

Affects 1.0.0pre.

Yes, not sure we want to support this. I will look into it when we implement some changes around Beta2

The unabbreviated syntax {{=sum(recorde, function (r) { return r.value; })}} should address your need.

[BorisMoore]

Yes, correct, using {{= expression}}, which is semantically equivalent to ${expression}, should allow using expressions that include } characters...
I missed that when I replied earlier...

Good catch - cheers guys!
