1.5.5 more than one element in negation filer ?

[Tom Zeller]

Using the latest 1.5.5 snapshot, a search filter of the form
( ! ( | ( objectclass=x ) ( objectclass=y ) ) )

returns error code 80 "Cannot add more than one element to a negation node".

ApacheDS 1.0.2 appears to support this search filter. Will 1.5.5 ?

Thanks,
Tom
