My apologies for asking a JFace question in the SWT group, but I don't see
a JFace group listed in the categories on the eclipse.org website.

I am trying to use a ListViewer in a Dialog. To this end I am looking at
the SectionsDialog source in the readmetool example source. My platform
is Windows 2000, and the source of my dialog class is as follows:

public class OpenPatientDialog
//extends ViewPart
extends Dialog
implements
SelectionListener {
protected IAdaptable input; // test only, remove later
public OpenPatientDialog(Shell arg0, String title) {
super(arg0);
m_title = title;
}
...
protected Control createDialogArea(Composite parent) {

...
// following is functionally verbatim from the example
List list = new List(grp, SWT.BORDER);
GridData data = new GridData(GridData.FILL_BOTH);
list.setLayoutData(data);
ListViewer viewer = new ListViewer(list);
viewer.setContentProvider(new WorkbenchContentProvider());
viewer.setLabelProvider(new WorkbenchLabelProvider());
viewer.setInput(input);
...
}
...
}

At runtime, the error I get is the following:

Unhandled event loop exception
Reason:
org/eclipse/ui/model/WorkbenchContentProvider

The code I have above is functionally the same as the example, meaning the
only change is the names of some of the variables (like the name of the
composite used to create the List object).

Any ideas?

jface questions should be asked on the eclipse.platform newsgroup.
