[eclipselink-users] NPE when updating entity where only @Element-collect

[Andreas Joseph Krogh <andreas@xxxxxxxxxx>]

Hi all.

 

I'm using EL-2.5.2 with PostgreSQL

 

I have one entity where the only field changed is an @ElementCollection, this results in the following code-path:

 

SQLUpdateStatement.buildCallWithoutReturning, line 64:

 

if (fieldsForTable.isEmpty()) {
    return null;
}

 

Then null is returned and assigned to the sqlCall-variable in SQLModifyStatement.buildCall:

 

public DatabaseCall buildCall(AbstractSession session) {
    SQLCall sqlCall = buildCallWithoutReturning(session); // null is returned here
    if ((getReturnFields() == null) || getReturnFields().isEmpty()) {
        return sqlCall;
    } else {
        return session.getPlatform().buildCallWithReturning(sqlCall, getReturnFields());
    }
}

 

Using the PostgreSQLPlatform, this is what happens:

 

public DatabaseCall buildCallWithReturning(SQLCall sqlCall, Vector returnFields) {
    SQLCall call = new SQLCall();
    call.setParameters(sqlCall.getParameters()); // BOOM NPE !!!!!!!!!!

 

Has anyone else seen or been bitten by this?

 

Thanks.
