Everytime there is an update this issue pops up and its very frustration . Th work around is create a new panel copy paste all the code for each and every panel class i ever created ! As the project grows its becoming a worse ! Loosing precious production hours . Cry for help !

A NoClassDefFoundError like that means that the product is not installed properly. Maybe you encountered an incomplete/partial update or some other problem.

Updating to the latest build on the Eclipse WIndowBuilder download page is the correct course of action. The "workaround" you describe won't actually do anything. You could just as easily open the class with a different editor to have the same effect with a lot less work. That workaround certainly won't make that exception go away if it is present. Only a full update or reinstall will do that.

Hi Eric , thank you for the response.
My previous procedure as you mentioned didn't work but something u mention i kinda did go ahead with . I uninstalled the plugin and all the dependencies and reinstalled an older version of the same plugin and it WORKED ! I work with 2 copies of the same IDE just to test out new plugins and sync my repositories for various reason like this and it worked on both my copies . Just to be on the safe side i did removed the update for this plug in one of my IDE copies to test it further .

One thing I don't understand is that when installing a fresh copy of WindowBuilder Pro, it installs 1.5.0 (Except for the GWT tools, which are up to date at 2.6.0). Doing an update right after the installation and it goes to 1.5.2 (Except for WindowBuilder CSS Support thatstays on 1.5.0)

1.5.2 is not working for me actually. On the design view, it goes to 4 different error msgs, each of them when I click on the reparse button. The 4th one stays

WindowBuilder encountered unexpected internal error.

This could be caused by a WindowBuilder bug or by a misconfiguration issue, conflict, partial update, etc.

If you are installing WB 1.5.0, that it is far from "fresh". That is pretty old at this point. You should always install the latest WB build from the WB download page. Anything else will be quite "stale" at this point.

A NoClassDefFoundError means that you are not installing all of WB 1.5.2. You should *not* try to do an update from 1.5.0 as that will only update the plugins from 1.5.0 and will not install any of the necessary code from 1.5.2.

Thk Eric, it worked fine. I was using the google page (developers.google.com/java-dev-tools/download-wbpro) instead of the Eclipse one (http://www.eclipse.org/windowbuilder/download.php).

But still weird. If I use the URL link for the update, it installs 1.5.1. It I download the JAR files (to install locally), it installs 1.5.2.

But doing an update after the URL link installation brought it to 1.5.2. So, all good.

I had the same problem and kept getting errors even after updating the Window Builder plugin to 1.6.0. (Got it from here http://www.eclipse.org/windowbuilder/download.php)

After some research, I found out that the GWT Designer version was 2.6.0 while the GWT Designer Core and GWT Designer Editor versions were 3.1.2, so I have uninstalled the GWT Editor plugin and installed the GWT Designer GPE which had the version 3.1.2 available, and this worked.

Hope this helps.

Btw, I'm using Eclipse Indigo.
