Eclipse Plugin (Visual Editor) install failure

I was trying to install version of it. Unfortunately I was getting error during install with following msg:

An error occurred during the org.eclipse.equinox.internal.provisional.p2.engine.phases.CheckTrust phase.
session context was: (profile=epp.package.jee, phase=org.eclipse.equinox.internal.provisional.p2.engine.phases.CheckTrust, operand=null → [R]
com.vaadin.wysiwyg.eclipse, action=).
Failed to prepare partial IU: [R]

Is anyone else facing the same issue? Is there a way to disable the eclipse plugin validation? I assume checktrust phase validates something about the plugin.

Thanks in advance,

When using the Eclipse update manager (Galileo and Helios M6), I see a warning dialog asking about installing unsigned plugins. By accepting to do so, the plugin is installed. If you are installing the plugin in some other way via p2, you should check its documentation.

Note that the visual editor plugin is at an experimental stage.
There is now some work in progress on it, stay tuned for a new version in the near future.
