Extended attribute default value using template

Hi all

Extended attribute is created for the entity meta class. Is not computed and has a list of values that is using a GTL template for list all Packages of that model. As default value it is needed to have a value of the parent package i create another GTL template and gave just one value hardcoded there (Customer). I selected checkbox Template and call the template like this %Code% lets assume that this is GTL template that i created.

When i create new entity i get in the Package (Subject Area) propertie for the entity %Code% as i didnt selected check box

Can somebody help me here please

thanks a lot
