The lock icon in EOModeler indicates that optimistic locking is  
enabled for that attribute.

You're post is a little light on details, but I would assume that you  
are encountering an optimistic locking error when trying to save.

Optimistic locking: <http://developer.apple.com/documentation/ 
LegacyTechnologies/WebObjects/WebObjects_5/Topics/ProgrammingTopics.

EOModeler: <http://developer.apple.com/documentation/WebObjects/ 
UsingEOModeler/index.html>

Some information that might help track down your issue:

- Database type and version.
- Attribute type suffering the locking failure.
- Stack trace of the error.
