I have done the following for changing the button text of 'Open Task' button.
Created i18n folder and file in the extension project
Given the new button text in the i18n property file
Also given the reference in the Component.js file. The extension project is deployed but text is not changed in the fiori app,
Just wondering whether implementing the hook method 'extHookChangeFooterButtons' of controller 'S3.controller.js' will help in this case?
Thanks
Vinod
