We don't directly send DSML, we have a custom version of Dsmlv2Engine
that uses org.apache.directory.api.dsmlv2.Dsmlv2Parser. The issue only
occurs if we provide the sort control, the code we have is working
otherwise.
I am curious if anybody out there is successfully using the sort control
with DSMLv2 (OSGi or non-OSGi setup) ?
If registering SortRequestFactory/SortResponseFactory was the only known
missing part (for OSGI setup) I suspect a bug in the
decorator/Dsmlv2Grammar/... Debugging I so far haven't been able to
pinpoint where it goes wrong but I will see what I can do, trying to
narrow it down and maybe produce a small test to reproduce the issue.

Thanks for the fix.
As I wrote initially I had already tried with registering the two
factories and got a ClassCastException.
I tried now with RC3 but as suspected I still get the same

I have the feeling that some link between DSML and codec is missing
for the (sort) control...
Most certainly. D you have a fragment of code I can play with to find
out what's going on ?
