Hello guys,
we are testing our first MDK Offline App and got two problems.
First how can we set sap-language to German? In Value Helps, Buttons and Place Holder everything appears in English. When we set the sap-language parameter in the service, default language of SAP is set to English. Where does system get this information from? We do not use SAP in English in Backend.
Second after clicking a Create Button we fire a CreateEntity to the backend. In our screen we got simple inputs, text areas and value helps. Everything works fine but the simple inputs look like they are all set to "non nullable". In the entity of course they are not set as nullable, because in normal FIORI app this is only needed for date fields and not simple strings (simple strings can be without value if not mandatory). In the normal FIORI app this works fine, but doing the same with MDK Offline App and same entity, simple inputs canot be send to backend when empty. If doing so, "canot set non-nullable" error appears for the corresponding fields in send request. Suprising this only happens in IOS phones. Android phones work fine. Where is the problem then?
Regards
Michael
