Troubleshooting
Since all logic runs in ABAP, you can debug everything in the ABAP environment. Set an external breakpoint, because HTTP calls abap2UI5 apps externally.
Backend
Set a breakpoint in your abap2UI5 app to debug the code. Check that the XML view builds correctly and that all events fire on the backend as expected.
Frontend
On the frontend, abap2UI5 behaves like a standard UI5 app, so the usual tools and debugging features work.
Debugging Tools
Press Ctrl+F12 to open the built-in debugging tools of abap2UI5:
From here you can review the XML View and check the Data Model bound to the view.
UI5 Inspector
Another option: the SAP default debugging tool, the UI5 Inspector.
Issues
If your code looks correct but you suspect a bug in the abap2UI5 framework, build a minimal sample that reproduces the bug and open an issue on the abap2UI5 repository — we'll investigate and fix it.
