Help defining a controller in Component.js

So I am following this tutorial, where all has gone well until I hit step 19.

I am following it along from within HANA Studio not the Web IDE and I have made one change in declaring the root directory.

The tutorial suggested (in step 4):
data-sap-ui-resourceroots='{ "sap.ui.demo.wt": "./" }'

I declared it as:
data-sap-ui-resourceroots='{"xsapp": "/xxxx/0RPO/XSAPPS/CD126_test/"}'

So now we have that out of the way, I believe my problem relates to how I am defining the Dialog within Controller.js. In the tutorial it starts like this:


], function (UIComponent, JSONModel, HelloDialog) {......}

My guess, is that my problem comes from line 4 above but I cannot workout what the full path refers to. I mean I know what the target is but this does not resemble my directory path which would be /xxxx/0RPO/XSAPPS/CD126_test/controller/HelloDialog.controller.js. I have also tried defining it with the full URI which looks something like:http://server:port/xxxx/0RPO/XSAPPS/CD126_test/controller/HelloDialog.controller.js and like: xsapp(which refers to the root directory)/controller/HelloDialog.

So what am I doing wrong.

    This parameter defines root path of your application. Take a look.

    data-sap-ui-resourceroots='{ "sap.ui.demo.wt": "./" }'

    Here your project path starts from sap.ui.demo.wt and to access particular controller you have to define it as


    And in your case you have specified it wrong. It’s exact syntax is.

    data-sap-ui-resourceroots='{ "<any path name>": "./" }'

    “./“ is your root folder of your app.

    Hope it’s clear.

    • What you explained was correct, it deals with declaring the root directory in the index.html. Which as I said, I have this sorted, I have made amendments to it but it still works as expected.

      My concern relates to declaring my controllers from the Component.js

      Thanks though for your input.
