Please add to this post any common mistakes we have done during initial UI5 devleopment (add solution also if available) --> use #resolved if the solution is provided Also post any issues that beginner UI5 developers are facing --> use #problem (If someone has helped in resolving an issue, please # their first name. Ex: #anubhav ) Issue: Application doesn't load. "Sources" tab in console doesn't show sap.ui.core.js library is loaded Root cause - Bootstrapping syntax: #resolved 1) Used incorrect bootstrap source - http:// instead of https:// - "sap.ui.core.js" instead of "sap-ui-core.js" 2) Used src="/resources/sap-ui-core.js" instead of
src="https://sapui5.hana.ondemand.com/resources/sap-ui-core.js" NOTE: src="/resources/sap-ui-core.js" can still be used if "neo-app.json" file was created in the project. "neo-app.json" is auto generated when we select the option to create 'HTML5 Application Descriptor' from the project folder.
