Bound Table not updated after createEntry on ODataModelv2 with deferred group

Prerequisites:

• An XML view with a sap.m.Table bound to an entity set of a ODataModel v2.
• Two-way-binding activated
• Deferred group = ‘groupId’
• Change set = ‘changeSetId’

Reproduction steps:

1. Add a new entity to the OData model using oModel.createEntry({groupId: 'groupId', properties: ...})

What is the expected result?

• The bound table should show the newly created entry.

What happens instead?

• The bound table does not show the newly created entry.

I can see in the ODataModel that the entry exists with a local id and properties are set correctly. But my table is not updated to reflect the data. Only after calling oModel.submitChanges() on the ODataModel, which goes to the backend OData service, these changes will show up in the table.

Plus one. We are having the exact same problem in our development right now, and searching through SAP Blogs, questions and archives show that several people have been facing this for years. Having to throw data from ODataModel to JSONModel just to be able to do these operations feels wrong.

Hi @one-github , @lucasheim , @rauar and @i328935 ,

the functionality you request is available with the OData V4 Model, please see API documentation: sap.ui.model.odata.v4.ODataListBinding.create. In case your service can be exposed also as OData V4 and all required features are available with OData V4 (see the restriction at the beginning of the documentation on the OData V4 Model) I recommend to go with the OData V4 Model.

As to enhancing the OData V2 Model, I have rather bad news. The enhancement will be rather complicated and thus time consuming. In the next months, probably the whole year, we would not have time to work on this requirement.

Best regards Mathias.
