---------------------------------
Fix Version/s: 4.2.1
5.0-M1
> Vertical Inheritance: Missing subclass attributes with joint prefetch
> ---------------------------------------------------------------------
>
> Key: CAY-2840
> URL: https://issues.apache.org/jira/browse/CAY-2840
> Project: Cayenne
> Issue Type: Bug
> Components: Core Library
> Affects Versions: 4.2, 5.0-M1
> Reporter: Jadon Hansell
> Priority: Major
> Fix For: 4.2.1, 5.0-M1
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> If you use a joint prefetch on a belongs-to relationship whose target is
> using vertical inheritance, the attributes on the child class are set to null
> instead of using the results from the database.
> It looks like this is happening when the attribute is read in
> DescriptorColumnExtractor.visitAttribute, it includes the 'p:' prefetch
> prefix in the data row key that gets built. Later, the data row result is
> read from a map without the prefix in the key, and is not found. This only
> happens on a joint prefetch, disjoint and disjointById work correctly.
