Hi
Just to let everyone know, if you are using prefetches and by mistake
use two routes to the same objects this exception will come up.
Example to illustrate:
SelectQuery on Company
added prefetches
Company.EMPLOYEE+"."+Employee.PERSON
Company.CONTRACTOR+"."+Employee.PERSON
will produce a runtime error.
The error message is a little confusing, is it easy to make it more
informative?
