AdapterFactoryLabelProvider doesnt work in TableViewer [message #418591]

Hi,
i am trying to set up a table containing EObject instances:

TableViewer viewer = new TableViewer(myTable);
//viewer.setLabelProvider(new AdapterFactoryLabelProvider(new
MyModelItemProviderAdapterFactory()));
viewer.add(myEObjectList.toArray());

If I use this without a LableProvider the rows are created i can see the
standard toString representations of the EObjects. But if i use the
Labelprovider Second line in the snippet), the rows remain white. I use
the same LabelProvider for a treeview, where it works fine:

public class LabelProvider extends AdapterFactoryLabelProvider implements
ILabelProvider {

public LabelProvider() {
super(new ModelItemProviderAdapterFactory());
}
}

Thanks for any help.

Did you set the content provider? I guess not, but that's kind of expected.

Does your model support column label providers? In Eclipse 2.4 there's
new support for populating a column viewer based on some property of the
object. Which version are you using?

No the list that i am providing is a list of referenced EObjects. So the
standard Content Provider should not work.

Yes it does...

Jonas,

I'm not sure what to suggest. Setting a breakpoints in the label
providers getColumText method will maybe help track down where things
are going astray...

Hi
I finally found the problem:
1. I had to turn on "Create column provider" in genModel
2. Set the lableprovider before populating the table!

Anyway, thanks Ed!
