History

#1 Updated by Daniel Crawl about 10 years ago

I'm getting another exception in NamedObjId that looks related. This one can be reproduced by opening demos/getting-started/06-WebServicesAndDataTransformation.xml, double clicking on Web Service Actor, then changing the method name. (Make sure your WebService actor source is updated).

#2 Updated by Daniel Crawl about 10 years ago

Fixed. There were two bugs: dereferencing a null container, and sometimes the referral list attribute was being created without a name.

#3 Updated by Redmine Admin over 6 years ago

Original Bugzilla ID was 4199
