Hello Maksim,
I've updated my project gregorwolf/crudkapsel today to make use of the sap.ui.model.odata.v2.ODataModel. Unfortunately the problem still persists. The project just works fine in a desktop browser. But on my Nexus 5 with Chrome the update does not work. I've checked with chrome://inspect/#devices debugger and see that in line 152 of the Detail.controller.js:
var oData = oModel.getData(sEntityPath);
the oData after pressing the save icon does still contain the old and not the updated data. In the desktop browser the oData variable contains the updated data.
Perhaps Frederic Berg and Jan Mummenthaler could help.
Best regards
Gregor
