Following this guide I used to create a SAPUI5 Kapsel application that supports Kapsel OData in offline mode.
However, the Web IDE project wizard does not allow me anymore to use the Northwind test service with a write-enabled URL like this http://services.odata.org/(S(individualkey))/V2/OData/OData.svc/ - Service is unavailable.
The service is unavailable because the URL is converted to lowercase, manually changing the URL called by Web IDE successfully returns metadata as expected, notice the upper-case S: https://webide-accountid.dispatcher.hana.ondemand.com/destinations/Northwind/(S(individualkey))/v2/odata/odata.svc/$metadata?format=xml
So the Web IDE wizard fails to access the test service and I have to create the project manually or use another service first. Maybe there is a bug?
