Problem : After setting the tag data-sap-ui-resourceroots the UI5 loading stops with the error “JSON.parse: unexpected end of data …”
Reason : Spring boot thymeleaf view formatter changes single quotes to double quotes, thus braking the valid JSON format of the tag.
<script src="/resources/sap-ui-core.js" id="sap-ui-bootstrap" data-sap-ui-theme="sap_belize" data-sap-ui-libs="sap.m" data-sap-ui-compatVersion="edge" data-sap-ui-preload="async" data-sap-ui-resourceroots="{"demo":"uidemo"}">
<!-- note the stupid double quotes in the json at the end of above line -->
<!-- this was originally single quotes - '{"demo":"uidemo"}' -->Fix :
- Make the landing page a static HTML instead of a view template (move from templates folder to static, in Spring boot).
- OR
- Move to Velocity or JSP formatters
