Hi!
I get a strange exception from time to time at start-up of my
application. Sometimes the same code works without problem. What does
the exception mean? I do not understand why NavPoint is not recognised
as the error-message says that NavPoint is a known entity name?
SCHWERWIEGEND [org.openide.util.RequestProcessor]
<openjpa-1.1.0-r422266:657916 nonfatal user error>
org.apache.openjpa.persistence.ArgumentException:
An error occurred while parsing the query filter "SELECT x FROM NavPoint x
WHERE x.type<>NavPointType.SystemMountain AND
x.type<>NavPointType.SystemAirfield ORDER BY x.name".
Error message: The name "NavPoint" is not a recognized entity or identifier.
Perhaps you meant NavPoint, which is a close match. Known entity names:
[NavPoint, NavPath]
