Bug in Odata Backend for Annotations

[moritz_ruff2]

Hello Everybody,

I've tried to use the "Smart"-Controls in UI5. For this task I developed a own Odata-Service via SEGW an followed following Tutorial: https://blogs.sap.com/2016/01/28/smart-table-backend-and-frontend-example

Unfortunally my Gateway seems to create "wrong"-Metadata.

This is the syntax the smarttable is expecting (found in the API):

This is what my Gateway delivers:

I found no possibility to change the Property-name in the SEGW.
Do you have any suggestions?

Thank you and best regards
Moritz Ruff

Hi Moritz,

The reason is probably that your Service Builder has an older version which didn’t support the data type (Edm.PrimitiveType) of the property. Please implement OSS note 2323443 - Edm.PrimitiveType Ignored while Importing a Vocabulary File.

Yellappa.

Thank yu for your input. We will implement the note and report back if it works.

HI Moritz

I got the same error. The generated ODATA is shown below.

Did you solve this problem?

Hi,

unfortunally we did not. We are currently trying to use SmartControls in an other project on newer GW-Server release but did not succeed so far.
I will report back if we find a solution...

I'am looking forward to the TechEd in Barcelona this year, so maybe someone from the SAP Team can guide me through the process....

Best regards
Moritz

Hi Moritz,

you can try out to create the annotations using code based implementation as I have described in my blog.

Hello ,

Did you try using the vocabulary chosen in step 9 on the quoted blog?(DataFieldForAnnotation)

BR.

Yes, this was the first one I tried. Later (searching for an solution) I changed to DataField because in the Mockserver.xml in UI5 Explored this annotations-type is used.
