RapidClipse UI Designer Error

I am new to RapidClipse IDE as my organization requested that I study and develop with it. After having installed version 2.3.1 windows edition, I created a project but the UI designer is showing an error and the widget palette is not showing anything. Below you can find the full stacktrace:

I have been able to solve this. Its probably a bug from the developers of RapidClipse. this is what i did:

The UI Libraries to display the designer and the pallette does not download when you create the project, so you will have to download the following:

  1. xdev-server-aa
  2. xdev-server-ui

from maven repository and include them in your library path. then you right click the project select maven and update project. Restart the RapidClipse IDE
