I really do not think there is any configuration you can do in the model related to you customization.
Actually for cm:name also there is nothing special in model to keep it unique.
It is just during creation of noderef it check for all the existing files and that too in particular parents only not through out the alfresco.

It also depends on how you created your custom model. Did you inherit from cmerson or cm:content or cm:folder or something like that maybe? If you did, then you already have the cm:name inherited in your type.

Hi Sradha,

Finally, you could create a unique field to your custom model? I currently have the same problem and I do not know how to solve it.

Thanks,

Hi Paul,

There isn't any XML configuration to define a unique field in custom content model. This cannot be achieved through configuration. Customization is required to get this implemented.
Here is a link to one of the forum post which suggests how to implement the unique field in custom content model. The approach is good. Take a look at it - https://forums.alfresco.com/comment/146372#comment-146372
Hope this helps.

I think what you want is a constraint. So you could use the cm:name as an example.

It may be that you need to add a new type of constraint. Off the top of my head I'd back up the constraint with a value in the attribute service.
