EMF.Edit - Problem with ITableItemLabelProvider [message #621504]

Hi,

i am working on a gmf-based editor and i want to display data of a model object in a table. Therefore i implemented the interfaces IStructuredItemContentProvider & ITableItemLabelProvider in my edit provider.

The code in the setInput method of the property section looks like this:

AdapterFactory af = getAdapterFactory(inputElement);
if (af != null)
{
afContentProvider.setAdapterFactory(af);
afLabelProvider.setAdapterFactory(af);

inputTableViewer.setContentProvider(afContentProvider);
inputTableViewer.setLabelProvider(afLabelProvider);
inputTableViewer.setInput(getEObject());
inputTableViewer.refresh(true);
}

The problem is now, that the methods getColumnImage & getColumnText are never called; instead the default toString is exectued; although my provider does implement the corresponding methods. I dont know why this in not working because for the Content Provider it is working. This means that getElements from IStructuredItemContentProvider is called.
Does anybody have a clue why this in not working for my ITableItemLabelProvider?

Any kind of feedback would be highly appreciated.

Greetings,
Florian

Florian,

If you used the GenModel property "Table Providers" it should generate
something that works. Did you update the factory to indicate it's a
supported type?

public LibraryItemProviderAdapterFactory()
{
supportedTypes.add(IEditingDomainItemProvider.class);
supportedTypes.add(IStructuredItemContentProvider.class);
supportedTypes.add(ITreeItemContentProvider.class);
supportedTypes.add(IItemLabelProvider.class);
supportedTypes.add(IItemPropertySource.class);
}
