[rules-users] Calling a function from another function in 5.0

[Chris Selwyn]

I don't seem to be able to find how to call one function from another 
function in Drools 5.0.
It works just fine in 5.1 but I am having to use 5.0 because my customer 
requires me to use a supported version.

Is this a known problem or is there really no way to do it?
