Eclipse debug mode losing style

Vaadin 6 / 7 / 8
1

With some Vaadin projects when
debugging
 under Eclipse (eclipse browser) all styling seems to disappear. As a result all page content appears left-justified on the page (Label icons do show up).

In this condition, the application is not usable and unable to effectively debug the application. Reduced to debugging via sys-outs in run mode (non-debug).

Working with:

  • Vaadin 7.1.3 (but behavior seen since 7+ - did not develop in pre-7 so not sure if it was same behavior)
  • Maven 3.0.4
  • Eclipse (juno, kepler)
  • JDK 1.6
  • Platform: macosx (10.8.4)

Once I compiled the SCSS (using: mvn vaadin:compile-theme) the debugging began to work well.
