Design view not opening

my vaadin eclipse plugin is not working. If i trigger the “Design” tab the CustomComponent is not loading in the View. Theres just this spinning-red-wheel(progress indicator) and a blank page.I tried to install different kind of eclipse versions. Also different xulrunner versions. Just created a fresh Vaadin 7 Project using the wizard. Everything works fine instead of the Visual Designer.
There are no further informations in Eclipse Error Log! Just the “normal” XULRunner Debug Message. Can you help me?
Windows 7 64 bit
jdk1.7 64 bit
Eclipse Kepler 4.3.1
Vaadin 7.1.8

Thank you!

Wich version of XULRunner do you have installed on your system?
→ Is XULRunner registered?

Have you changed someting in the sourcecode of the class before opening it in the designertab?

Is this a problem existing on many classes or just one class?


i have installed Mozilla XULrunner directly in my eclipse folder and put “-Dorg.eclipse.swt.browser.XULRunnerPath=xulrunner” at the end of my eclipse.ini. The problem exists in every class i create with the wizard - even totally fresh created VAADIN 7 projects.
At this moment i create my uis on my own… its not the “org.eclipse.core.runtime.CoreException: Failed to find or parse visually editable class” exception you get when yo manipulate code that is annotated with “@AutoGenerated”.


I’ve got similar issue, however the design-tap or the file name isn’t showing at all when I open with the Vaadin Editor. Like this:


Hello Matias,

take a look at your Error log when you open the Vaadin Editor.
To get the Error log View in eclipse:
go Window->Show View->Other->Error log


Yeah there are two exceptions:

Unable to create class ‘org.eclipse.ui.internal.e4.compatibility.CompatibilityEditor’ from bundle ‘692’

org.eclipse.e4.core.di.InjectionException: java.lang.UnsatisfiedLinkError: org.eclipse.swt.internal.mozilla.init.XPCOMInit.GREVersionRange_sizeof()I

Thanks a lot, that seems to work for me. Still complains about not finding the XULRunner though.

Hope you’ll get it fixed as well.
