Re: [eclipselink-users] NPE when updating entity where only @Element-collection has changed
I have no idea (I'm just an EclipseLink user like you and never used it with PostgreSQL), but... what if you compare the same buildCallWithReturning implementation on another SQLPlatform (MySQL or such)? Would it throw NPE as well if sqlCall is null?
You may understand if the problem is in the PostgreSQLPlatform or in the fact that sqlCall is null...

Hi.
 
I'm getting bitten by this again, using EL-2.6.2. No hints of what might cause this?
 
Thanks.

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.
