I see MVEL supports inline of lists, but unfortunately, this syntax seems not to be supported by 'from' construct.

From drools expert documentation @ 4.8.2.8 Conditional Element from i read:

"The expression used to define the object source is any expression that follows regular MVEL syntax."

I realized by testing that the suggestion works for a "memberOf" construct, but not in a "from" clause.

Is this expected behaviour or is this a bug/unsupported feature?

Thank you in advance.
