Details
When a drawing sheet from NX10 with smart Lightweight views is opened in NX12, all drawing views are out of date.
When changing the representation style of the view, all leader lines will loose the connection and will be displayed brown.
A change between the lightweight and exact representation will lead to this loss of connection. In NX10 the connections will not be lost when changing the representation.
Solution
The behavior in NX12 is working as designed.
As of NX11, when smooth edges is off in smart lightweight views, they are no longer processed in the view. This is a deviation from exact views which improves performance. The annotations in the exact views are on smooth edges which are no longer visible in the view, so they are going retained.
There are two Workarounds:
Workaround 1: Turn on smooth edges for the view, which will re-awaken the dimension and either hide or apply view dependent erasures on any unwanted smooth edge curves
Workaround 2: Another option is to associate the annotations to non-smooth edges or model faces so they don't go retained when converted.
