I have attempted to tweak my ‘User’ entity at
‘Application.finishInitialization()’,
But when the app tries to get a User object, it blows up:
ERROR er.extensions.eof.ERXEntityClassDescription - Unable to register
descriptions for class: class com.es.eo.User
RuntimeException: Dummy
at
er.extensions.eof.ERXEntityClassDescription$Factory.registerDescriptionForClass(ERXEntityClassDescription.java:615)
at
er.extensions.eof.ERXEntityClassDescription$Factory.classDescriptionNeededForClass(ERXEntityClassDescription.java:392)
The smallest change that causes the error above is:
---
EOEditingContext tmpEc = ERXEC.newEditingContext();
EOEntity entity = EOUtilities.entityNamed(tmpEc, "User");
entity.setClassName("com.es.eo.User"); // changed from 'com.mg.users.eo.User'
---
I guess I need to re-initialise or register something, but I am not sure what
exactly.
Thanks,
Mark
