Hi all ,
I have defined my Label Decorator based on the object type

<extension
point="org.eclipse.ui.decorators">
<decorator
adaptable="false"
class="com.rse.sevices.files.eom.decorators.LockedOnly"
id="com.rse.sevices.files.eom.decorators.LockedOnly"
label="ELocker Decorator"
lightweight="true"
location="BOTTOM_RIGHT"
state="true">
<enablement>

<objectClass
name="com.rse.sevices.files.eom.EOMHostFile">
</objectClass>

</enablement>
</decorator>
</extension>

I have got two views in my plug-in ... a treeviewer and a tableviewer

For both views I do:

---<tree>---
IWorkbench workbench = getSite().getWorkbenchWindow().getWorkbench();
viewer.setLabelProvider(new DecoratingLabelProvider (new
NavigatorViewLabelProvider(), workbench.getDecoratorManager()));

---<table>---
viewer.setLabelProvider(new DecoratingLabelProvider (new
FolderExplorerLabelProvider (), workbench.getDecoratorManager()));

now the TreeViewer Label provider extends LabelProvider and in the get image
I do use the

Image decorated = decorator.decorateImage(image, element);
if (decorated != null)
return decorated;

to get the decorated image ... FINE ... WORKS!!!

THE PROBLEM IS IN THE TABLE VIEWER ...

public class FolderExplorerLabelProvider extends LabelProvider implements
ITableLabelProvider
I had to extends using LabelProvider to use the decorating label provider
(as I found in a few table viewer example) ...
But when it comes to rendering the table ... the getText is called instead
of the

getColumnText(Object element, int columnIndex)

what am I doing wrong?

Thanks

note: if I set the table label provider directly to the
FolderExplorerLabelProvider everything works fine (with no decorator)
