Hi,
change the line:
$printouts[] = new SMWPrintRequest(SMWPrintRequest::PRINT_PROP, 'has
Connection', 'has Connection');
into:
$printouts[] = new SMWPrintRequest(SMWPrintRequest::PRINT_PROP, 'has
Connection', SMWPropertyValue::makeUserProperty('has Connection'));
That should do it.
Best regards, Stephan
