Observer Port Links are gone

I created an Observer in a Simulink test harness and mapped signals to Observer Ports. Then I saved and closed the test harness and the Observer. When I reopened the test harness from Test Manager and clicked "Manage Observer" in the Observer model, previously linked signals to the Obersver Ports are not there anymore. Note that the Simulink test harness model is not detached from the main model (i.e., internally saved inside the main model). The links of the Observer Ports are preserved when created from a detached (or separated) harness model. Any insights would be appreciated.

Hi Jung Soon,

Apologies for the delay in answering this question. This is a known issue and a fix is available for R2022b and beyond. If you are on an earlier version, you can work around this issue by using externally saved test harnesses.

Regards,

Krishna
