Description Miles Daffin CLA 2011-07-19 16:02:50 EDT 
When building a large aggregation I get this exception each time. I am using   b3 Aggregator Editor (Incubation)	0.2.0.v20110718-2116	org.eclipse.b3.aggregator.editor.feature.feature.group.

Comment 1 Thomas Hallgren CLA 2011-07-20 00:56:16 EDT 
A sample b3aggr file would be very helpful. Would that be possible here or does it include proprietary stuff? If it doesn't but still is rendered sensitive, perhaps you could email it to me?

Thanks.
Comment 2 Thomas Hallgren CLA 2011-07-20 02:36:02 EDT 
I found the cause of this. It happens when a legacy site (one that only has a site.xml) has IU's for which no artifacts has been generated. A partial IU can then not be resolved. A warning will be issued when this happens since it's not fatal and I think installing this IU further on will just be a no-op.

Fixed in rev. 1536.
Comment 3 Miles Daffin CLA 2011-07-20 12:24:30 EDT 
Thanks Thomas. The model in question would only work in our environment, so I could not provide it. I have run the build again a couple of times and have not seen this error again yet.
Comment 4 Miles Daffin CLA 2011-07-25 07:08:26 EDT 
Still not seen this again. Closing.

[Bookkeeping change only. Moving bugs to the new "home" of aggregator, CBI.
Made no changes to assignee's for closed bugs, even though some were old inbox.]
