In a drools rule I'm trying to build logic using Java's ternary operator like this:

rule "ternary"
when
    $foo: Number() from 0
    $bar: Boolean() from ($foo > 0 ? true : false)
then
    System.out.println("value of $bar: " + $bar);
end

The compilation of the rule fails with the following exception:

Looking at the ExpressionTyper class this looks like a yet unsupported case to me.

Ternaries in general seem to work - an expression like $bar: Boolean() from (1 > 0 ? true : false) compiles fine.
