Validation messages not displayed for mandatory fields in child (item) entity in ABAP RAP behavior definition

[mmarkvillanueva]

Issue description

I’m working on a managed ABAP RAP BO with a header entity and an item entity.
Validations in the root entity behave correctly: custom error messages from the behavior pool appear and affected fields are highlighted in the UI.

However, validations inside the item entity do not behave as expected.
Instead of receiving the custom messages raised in the behavior pool, the UI only shows the generic message:

“Resolve data inconsistencies to save changes.”

The specific fields in the item table with errors are not highlighted either.

This has been raised on the below SAP Community forum; however, this doesn't solve this particular use case which is validation in the child entity.
https://community.sap.com/t5/technology-q-a/behavior-validation-messages-are-not-displayed/qaq-p/13761252

Another user (Robert_Schulte) reported the same issue when performing validation in a child entity, but the thread did not get an answer.

Can you provide a working sample for this use case in your documentation? Thanks!

Hi @mmarkvillanueva, thanks for your contribution. Could you point out the UI5 documentation this is referring to? That would be helpful.

Hi @mmarkvillanueva, my assumption is that you would expect to find this information somewhere under https://ui5.sap.com/#/topic/03265b0408e2432c9571d6b3feb6b1fd. If this is the case, I can pass on your request.

Hi @mmarkvillanueva, would you mind helping me out?
If your request is either development-related or not related to the SAPUI5 documentation, we have to close this issue here, and this is a topic for another communication channel.
If it is related to the SAPUI5 documentation, I assume this is an issue in the SAP Fiori elements documentation, but I would appreciate your confirmation. Thank you!

[mmarkvillanueva]

yes it's with the SAP Documentation. Can you provide the link where I can log the feedback?

[KvM2]

Yes, but which documentation? This repository is for SAPUI5, and I still assume that this is about the SAP Fiori elements documentation: https://ui5.sap.com/#/topic/03265b0408e2432c9571d6b3feb6b1fd. If this is not the case, please let us know.
