Problem with query pattern and extents
Hi,
I have a problem using patterns for querying
(case files attached as patch bellow for more precisions)
My query is two-level deep with two search paths,
all classes being referred through the same interface
I interface implemented by all classes
A refers to I implemented by B and B2
B, B2 refer to I implemented by C
I search all instances of A using a test on b.c
Although I put both B and B2 in the pathClass hints
for the query, only the first one is taken in account
and my result is partial
This is backed by some code -study, but I cannot say
wether I use this correctly or not.
In either case, what is the desired method to achieve
my goal, without having to manually join multiple
queries.

hi loic,
there's a new feature to support pathHints per criteria. this could probably
help. btw the attachement got lost.
