Hi Mark,

We could reproduce the problem of sending feedback (Leave feedback), but 
to try the fix, we would like to start DAWN v1.0 (by Buckminster). Now 
here is a problem, because product validation says this (and DAWN does 
not start):
org.dawb.passarelle.actors.edna
   Missing Constraint: Fragment-Host: org.dawb.passarelle.actors; 
bundle-version="1.0.0"

Does anyone know how to make that problem disappear?

While we are it, two more notices, any idea is welcome.
1) In org.dawb.workbench.product, in MANIFEST.MF, on Dependencies tab: 
there are features marked with red cross, because probably those do not 
exist. However one is not marked, org.dawb.edna.feature. Is it safe to 
delete these features from this tab?
2) We tried to do something about the Fragment-Host problem, and found a 
link "Find this fragment's host plug-in" at Dependency Analysis on 
Dependencies tab of (any) MANIFEST.MF. When we click on it, eclipse 
writes to the Error log. Message: Unhandled event loop exception, 
Plug-in: org.eclipse.ui. Any idea about this?

Cheers,
Gábor
