> Can't use function names as a path in a string-based expression
> ---------------------------------------------------------------
>
> Key: CAY-2736
> URL: https://issues.apache.org/jira/browse/CAY-2736
> Project: Cayenne
> Issue Type: Bug
> Components: Core Library
> Affects Versions: 4.1.1, 4.2.B1
> Reporter: Nikita Timofeev
> Assignee: Nikita Timofeev
> Priority: Minor
> Fix For: 4.2.B2
>
>
> Path like {{db:year}} causes expression parser to fail even if this is a
> normal DB attribute name.
> There's no workaround for this, if you need to parse expression from string.
> Fix would be to allow such names for explicit path syntax (i.e. for {{obj:}},
> {{db:}}, {{dbid:}} and {{enum:}}). If needed this could be added to the
> simple object path as well at the cost of some performance degradation.
