Hi Dave,
Just to clarify, the code you use for creating the newIU below, do
you use that for creating the IU's that you pass as roots to the
traverse query? If that's the case, then I understand why you have a
problem. The IU doesn't have any requirements so naturally, the
query won't find any matches.
You need to query for the root iu's first, using a standard IU query
(with id and version) and then use the result from that query as
root IU's into the traverse query. This can be done using two
queries but you can also do it one single query also, like so:
select(iu | $0.exists(v | v.id == iu.id && v.version ==
iu.version)).traverse(parent | ...
You then pass a collection of IVersionedID instances as $0. There is
an implementation class called VersionedID that takes a constructor
with id and version that you can use.
HTH,
Thomas Hallgren

InstallableUnitDescription iuDesc = new
MetadataFactory.InstallableUnitDescription();
iuDesc.setId(id);
Version
version = Version.create(versionString);
iuDesc.setVersion(version);
ArrayList<IProvidedCapability> capabilities = new
ArrayList<IProvidedCapability>();
capabilities.add(MetadataFactory.createProvidedCapability(id,
id, version));
iuDesc.addProvidedCapabilities(capabilities);
return
MetadataFactory.createInstallableUnit(iuDesc);
}
Thanks again,
Dave
