I got little confused with your statement "The issue is even though we have added 2 to 3 cases that are appended a page lists in the D Page, only one page list is being show under pyWorkpage"

Do you mean to say that, each case is added as an entry in data page which is subsequently referred to a page list under "pyWorkPage"? And this page list isn't getting updated during runtime?0

As per my knowledge, there is some discrepancy in the design. Data Page is loaded periodically or at reference. In your case, both these refresh strategy would be useless. Because, neither the case would be added periodically nor "Reload once interaction" will work, as no reference is made to update the data page content thus it's available in the page list under pyWorkPage.

Could you elaborate on your business requirement along with screen-shot for better understanding?

Any idea?

If you are using Refer to a datapage in property (which is of type page), then pyWorkPage should also show the latest data page values.

what is the refresh strategy of your data page? pyWorkPage and datapage you are verifying, are both in same thread?

It is editable thread level data Page. And the structure is list which is same as that of property and both Data Page, pyWorkPage are in same thread scope.

Data page should have results in the form of pxResults, each pxResult will be mapped to page list property.

Also can you try making the data page read only once and test this.

"Data page should have results in the form of pxResults, each pxResult will be mapped to page list property." yes it is like that. We can't test it by changing to ReadOnly as the application flow will fail.
