That looks familiar. Pierre and I fixed a bug in this a while back. Are you using the current (i.e. up to date) ones from Houdah frameworks?

Hello All,

I am finally getting the chance to use the QualifierAdditions from Pierre Bernard (thanks Pierre!). I am using the following code that generates a NullPointerException. Can anyone see what I have done wrong?

I am trying to show all Artifacts that have not been specified as "favourites".



public EOFetchSpecification getPubliclyDisplayed() {

EOQualifier q1 = new EOKeyValueQualifier( "userName", EOQualifier.QualifierOperatorEqual, applicationUser.userName());
ExistsInRelationshipQualifier q2 = new ExistsInRelationshipQualifier("applicationUsers", q1);
// the inverse
EONotQualifier notq2 = new EONotQualifier(q2);

// EOQualifier q3 = new EOAndQualifier( new NSArray( new Object[] { q1, notq2 } ) );
EOFetchSpecification fs = new EOFetchSpecification( "Artifact", notq2, null );

return fs;
}
