[equinox-dev] OSGi Declarative Services, Component Reference, Target Par

["cu@xxxxxxxxxx" <cu@xxxxxxxxxx>]

Hello from Germany,

this is my first post to this list. I hope you can help me or we can help us together.

I get an IOException if I define a LDAP AND-Filter-_expression_ for selection an appropriate target service (details see below):
...target='(&(test=A)(test2=B1))'

The problem is the boolean ldap-and-operator, the ampersand. 

After adjusting the "&" to "&" the parse error is gone as expected.
I'm not sure, but can this be the intention? Must the filter definition (with the original LDAP syntax) adjusted to make it compatible to the xml universum?

The component.xml was generated from my sources by the great Bndtools from Neil Bartlett (a small advert ;-)
:
@Reference(name="testRef",optional=true,dynamic=true,target="(&(test=A)(test2=B1))")
private void bind(ITest test, Map<String, ?> configuration) {...}

I'm pleased to read your suggestions?
