Hi Axel,
I found this code snippet in a template (I don´t use it anymore because I set the i18n model in my manifest.json file):
// Always use absolute paths relative to our own component
// (relative paths will fail if running in the Fiori Launchpad)
var oRootPath = jQuery.sap.getModulePath("test_hanatrial.mockdata");
// Set i18n model
var i18nModel = new sap.ui.model.resource.ResourceModel({ bundleUrl: [oRootPath, mConfig.resourceBundle].join("/")
});Please try this (of course adapted to your environment / paths). I guess the issue is related to wrong path.
Best regards,
Sebastian
