spinner.gif not loaded from Valo theme?

In my project implementing
Vaadin 7.7.6
currently, the page loading indicator spinner.gif cannot be loaded at application startup.

Google Chrome’s Inspector (Ctrl + Shift + I) says:

Failed to load resource: the server responded with a status of 404 (Not Found)

Mouse over on missing resource spinner.gif shows me path

http://localhost:8080/my_project/VAADIN/themes/my_theme/img/spinner.gif

In
Jouni Koivuviita
tells:
“there’s a suitable spinner GIF in Valo in valo/shared/img/spinner.gif”
which I found in

vaadin-themes-7.7.6.jar I copied this .gif to my_theme’s image folder and now correctly see a loading indicator on application startup.

my_theme’s scss is based on the initial theme Valo from this Vaadin archetype:

<dependency> <groupId>com.vaadin</groupId> <artifactId>vaadin-archetype-application-example</artifactId> <version>7.6.1</version> </dependency I wonder if it is intended that I have to copy the spinner into my_project’s image folder first, or what the reason may be?

I finally got to the following conclusion:
obviously my_theme.scss, which is a copy of Valo’s styles.scss which I saved to new path my_project/VAADIN/themes/my_theme/ and extended it for our needs, is searching for images in subfolder

/img now, which explains the “missing” spinner.gif.
Such, this question may be closed.
