Hi,

We are trying to implement a properties page on one of our model objects.
The model object is implementing IAdaptable. The gett adapter code (shown
here)

public Object getAdapter(Class adapter) {
if ( adapter.equals(IPropertySource.class) )
return new PropertySourceAdapter(this);
else
return super.getAdapter(adapter);
}

I getting called but is failing with a class def not found exception.
Here is the stacktrace.

!ENTRY org.eclipse.jface 4 2 2005-10-06 16:07:58.304
!MESSAGE Problems occurred when invoking code from plug-in:
"org.eclipse.jface".
!STACK 0
java.lang.NoClassDefFoundError:
org.eclipse.ui.views.properties.IPropertySource

We have verified that the org.eclipse.ui.views plugin is included in the
project and is available, as we can load the Properties View. Has anyone
seen this issue before ?

Here are the specs on the machine

Windows XP Pro build 5.1.2600.2622
jre1.5.0_04 / 1.4.2_08
Eclipse 3.1 buildId=I20050627-1435

We already have the dependency set, and have verified that the
org.eclipse.ui.views jar file is in the plugins directory. We can load
the properties views provided by the plugin, but when we try and use
IPropertySuorce it dies with the noclassdef error.

you don't include any dependency plugin (org.eclipse.jface or like)
