Hello ,

I am working on content model and want to use aspect inheritance.

Below is my code  where I have inherited aspect dm:customer123 from aspect dm:customer and inherited only single property.

It execute without error but when applied inherited aspect(dm:customer123) to the content ..it displayed all the properties (dm:customername,dm:customerid,dm:customercontract )from the parent aspect where it suppose to display only single property(dm:customername).


has anyone faced such a problem … ??

is there any way to solve this problem ??


Thanks in advance !!

Ashwini,

When you define an aspect as a child of another aspect, the child aspect inherits all properties of the parent aspect. You cannot selectively inherit a subset of the parent's properties. This is also true for types.
