Goal

Using Oracle jDeveloper (10g), the customer is trying to add a new transient column to the VO 'StructureLevelVO' seeded column name 'ActualEffort' (which is in hours) and one transient column i.e. 'ActualEffortInDays' (which will be in days format) based on the value present in 'ActualEffort' Columns.(8 hours=1 day).

While doing VO Extension in JDeveloper to achieve the above requirements, the following error is received in Attribute Mapping Window:

 "each row in the query result columns must be mapped to a unique query attribute in the Mapped Entity Columns" and "There are java errors for this object."

The issue is happening only for StructureLevelVO. All other VOs are working fine with JDeveloper. The Oracle JDeveloper support team advised that the issue is with the VO object and not related to JDeveloper tool.
