Regarding Polymorphic View Usage Behavior -2

Hi Steve,

I tried the solution you listed in the forum post, but still the value is not coming up at the UI.
Here, want to show you the steps I did, and where I stand right now:
As show in the following figure:

I am using PolyTestTableBase1VO as my Base VO. Now I filtered the query to fetch only the records with descriminator value as ONE.
As a result I just need to add 1 subtype to the Base VO to test the pageDef changes. The descriminator value in BaseVO is null to get all the records.
In the following figure, you can see that the descriminator value in ChildVO is ONE, and its added as a subtype to Base VO in AM's data model, and the attribute value is visible in AM Tester:

The following figure shows the structure of the page, where the BaseVO is dropped to create the table, and I added the extra column to render ExtraAttr1 value.
I want to render column always so no condition is added for rendering.

The following figure shows the pageDef content, where the subtype details are added as second nodeDef:

And the following figure shows that the value is not visible:

Could you please tell me what I am missing now?

Thanks.
