When i create a new JFrame or Swing component and switch it to Design mode, then the eclipse will show the error Message "java.lang.Error: Cannot call invokeAndWait from the event dispatcher thread". So what is the problem to make this error?

When i create a new JFrame or Swing component and switch it to Design mode, then the eclipse will show the error Message "java.lang.Error: Cannot call invokeAndWait from the event dispatcher thread". So what is the problem to make this error?

Try this with the latest v3.0.1 build.
