Do not use Violet 0.21.1 on Eclipse!

We identified some problems with Violet 0.21.0 and Violet 0.21.1 on Eclipse. Using this two releases, you are not able to edit properties on diagram's elements. This is mainly due to the AWT-SWT Eclipse gateway. We're working on it to publish a fixed version.

Note that this releases are OK when they are used outside from Eclipse (as a standalone program, Java applet or Java Web Start)
