Cannot apply CSS through GWT WindowBuilder editor for a multiple modules/Entrypoint application

Question

I usually use GWT WindowBuilder editor to design my GWT application UI, however I refactored my application to implement multiple modules/EntryPoint as described in my other post

Now I am getting this error "There are no CSS files referenced from modules HTML." when I click the CSS button from the Property Editor of the WindowBuilder editor.

Is there any way to fix this error.

Answer 1

If your web application files are in war folder. Make a subdirectory war/css and put your css files there. Then go to your-module.xml configuration file and declare this folder as public:

<public path="css" />

Now reload the Windows Builder Design View and automatically Windows Builder will map your css files.

Answer 2

The solution is simple,

I created a package like this:

com.mycompany.css

and put the CSS there and it works.
