It was adviced to change the PEP.createLookup method to return the collection of LookupItems instead of creating the Lookup itself. Current design has the performance drawback as it requires to use ProxyLookup for composition Lookups created by all PEPs registered for the PM. This was solved in lates revision of Looks API (see Look.getLookupItems method). We should adopt this design too.
As described in http://www.netbeans.org/servlets/ReadMsg?msgId=619519&listName=nbdiscuss the current work on projects prototype has been stopped.
