[rules-users] MVEL curly braces position - bug or feature?

[nickS]

Hi

I've been learning drools ands I saw that there is a Fibonacci example, so I
thought I'd write my own using mvel as the dialect and then compare it to
the model solution.

However, I couldn't get mine working. It parsed but the behaviour was very
odd. It kept ignoring the modify block in my recurse rule and consequently
it went into an infinite loop. I compared it to the 'approved' solution and
the two were pretty much the same, except that it worked and mine didn't.

After a lot of checking I noticed that I had started my curly brace on a new
line after modify but the example had continued straight after the closing
brace of the modify.

Works //

modify ( f ){
        value = 1
       };

or

 modify ( f ){value = 1 };


Doesn't Work //

modify ( f )
{
      value = 1
 };


Does anyone know if this is a bug or a feature?
