ShowPageMap error when I try to open an object page: "Can not open page - please check source code"

Hello Experts,

For a customer project, we are using BTP with SAP Business Application Studio and OData V2.

• We generate an SAP Fiori elements application based on the SAP Fiori List Report and Object Page floorplans
• We have a table with multiple views. I am able to open with Show Page Map the object page from first view of the table, but when I try to set the property useIconTabBar true for the object page from the second view, I get the error: "Can not open page - please check source code".

Do you have any idea how to pursue further with this issue?

Thanks for any help,

Ioana
