I created a new Eclipse RCP project (based on the with a View template). If I open the new View in the Design tab I receive the following error:

org.eclipse.wb.internal.core.utils.exception.DesignerException: 103 (Unknown GUI toolkit). test.View
at org.eclipse.wb.internal.core.parser.JavaInfoParser.prepareParseContext(JavaInfoParser.java:1198)

I avoid the full Stacktrace, if you need it please let me know.

Any advice what could be causing this? Im using Eclipse 3.7.

Best regards, Lars

I tried this and it worked just fine. Based on the error, there are two possible causes that come to mind:

1) The project is not configure properly and has a classpath issue of some sort, or

2) WindowBuilder is not configured to edit SWT/RCP files (e.g., no SWT Designer installed).

Thanks Eric for the reply, I used the Indigo update site and only installed all package s with "WindowBuilder". After installing SWT Designer everything works again.

Thanks again.

Good. Everything labelled "WindowBuilder" is the core engine, so you need support for at least one UI toolkit (Swing, SWT, etc.) in order to do anything useful.
