Same problem here, also need help.
Another problem with CloudShare, that my SAPUI5 runtime is not installed by default(or at least, not activated).
Fresh install of HANA environment and:
Error 404: hanacloud:8000/sap/ui5/1/resources/sap-ui-core.js
However, ui5 package is in the repository. I have tried "Redeploy" and "Activate", nothing helps.
The missing runtime leads to blank pages in formLogin and both web IDEs.
Thanks for taking a look.
