[ http://issues.apache.org/jira/browse/TAPESTRY-783?page=all ]
Howard M. Lewis Ship updated TAPESTRY-783:
------------------------------------------
Priority: Critical (was: Major)
The core issue is that the asset engine service is needed when constructing
PrivateAsset instances. Now, at the core of this, is the fact that we're
trying to create PrivateAsset instances in the first place; that's a bad idea,
they should be passed in to components and other code, not created on the fly.
Bad design.
