I have an assembly wherein I cannot get an exploded view to show from a sub-assembly configuration.

Assembly
---Sub-assembly
------Default configuration
------Configuration 1
------Configuration 2
---------ExplView1

I can stand alone open Sub-assembly with Config. 2 showing and see ExplView1.

If I highlight the Sub-assembly within the Assembly in the Feature Manager tree, then RMB to see the component properties, I see the 3 configs, but the ExplView1 is not in the pop-up as a subset of Config. 2. If I "Open Assembly" from the same RMB location, Sub-assembly opens with the exploded view showing...

Any ideas? Everything is loaded resolved.
