Adding custom css to existing theme is not working 8.1.1.11.5

Hi,

I have an Applet PR with styles defined in a css file.

I followed the below steps to add the custom css to the existing theme.

But I am not able to see the changes. It works fine if I add the styles in vanila "theme-gray.css" file.

• Created a  custom CSS “my-style.css”  and placed in the below folder

     \Siebel\8.1\Client_1\PUBLIC\enu\FILES\custom

•     Edited the theme.js file that resides in the folder:   scripts\siebel\custom\ as follows

              

SiebelApp.ThemeManager.addResource(
    "GRAY_ACCORDION",
    {
       css : {

      "new_360style" :"files/custom/my-style.css"
    }
    }
);

• Registered theme.js under application desktop platform  from manifest admin.
