> I am working with a project with nested objects.
> I have a rule in which I need to make use of a function. If I use this function on a variable in a nested object it does not work (I get a compilation error):
> Using the nested object accessor approach (compilation error "Unable to Analyse Expression"):
>         ObjectA( objectB. ( (someFunction(someVariable)) == 0 ) )
> EDIT: The same compilation error occurs as well when just using a more complex operation on variables in nested objects as well (updated project on GitHub):
>         ObjectA( objectB. ( (someVariable == 0 || someVariable == 1 ) || (someVariable > -1 || someVariable < 2 )) )
