Error while selecting entity

Question

Hi
I keep getting the "JBO-26080: Error while selecting entity for Units" error. Below is the query in my View Object. If I remove the Units(Enitty) from the query it works fine but I need to have that in the query. This error occurs only when I do "Reset" on the screen which in turn calls "getSearchProgramView().getCurrentRow().refresh(Row.REFRESH_WITH_DB_FORGET_CHANGES);"
Can some one explain how to get rid of this problem? When I run the query in TOAD it works fine.
SELECT Programs.PROGRAM_ID,
Programs.CATEGORY,
Programs.NAME,
Programs.PROGRAM_COORDINATOR_ID,
Programs.PROGRAM_ASSISTANT_ID,
Programs.MANAGING_UNIT_ABBR,
Programs.CREATED_BY,
Programs.CREATED_DATE,
Programs.LAST_UPDATED_BY,
Programs.LAST_UPDATED_DATE,
Persons.PERSON_ID,
Persons.USER_NAME,
Persons.FIRST_NAME,
Persons.LAST_NAME,
Persons1.PERSON_ID AS PERSON_ID1,
Persons1.USER_NAME AS USER_NAME1,
Persons1.FIRST_NAME AS FIRST_NAME1,
Persons1.LAST_NAME AS LAST_NAME1,
Categories.NAME AS NAME2,
Categories.CODE AS CODE1,
Units.DESCRIPTION,
Units.CODE
FROM PROGRAMS Programs, PERSONS Persons, PERSONS Persons1, CATEGORIES Categories, UNITS Units
WHERE ((Programs.PROGRAM_COORDINATOR_ID = Persons.PERSON_ID(+))
AND (Programs.PROGRAM_ASSISTANT_ID = Persons1.PERSON_ID(+))
AND (Programs.CATEGORY = Categories.CODE(+))
AND (Programs.MANAGING_UNIT_ABBR = Units.CODE(+)))
Thanks

Hi,
for those who have encountered the same problem as me, you should check that the table name sql query is of the form Name_Schema.Name_Table.
For this right click on the entity in the workspace> edit entity> Database Objects> Schema Objects and add the schema name before table name( Name_Schema.Name_Table).
thanks,
