== operator in Simple expressions

[Antoine DESSAIGNE]

Hi everyone,

We had a unexpected behavior with this simple expression:
<setHeader headerName="isFour">
    <simple>${body[value]} == 4</simple>
</setHeader>

It does not return true or false but a string like "4 == 4".

The documentation is unclear about == operator used in expressions (and not
predicates). Is this the desired behavior ?

Thanks a lot,

Antoine.
