[RAP E4]Image can't be seen in a treeviewer [message #1731951]

Hi,
I created a treeviewer and set label provider like this:
treeViewer.setLabelProvider(new ViewLabelProvider());
class ViewLabelProvider extends LabelProvider {

@Override
public Image getImage(Object element) {
return PlatformUI.getWorkbench().getSharedImages().getImage(ISharedImages.IMG_OBJ_ELEMENT);
}
}

After I runned the application the label can be seen but the image cannot.
Please help, thanks.
PS: The source code is in ProjectManagementPart.java

You should not have access to PlatformUI.getWorkbench() in an e4
application. RAP e4 does not support mixed mode like Eclipse 4 on the
desktop does, so you need to remove all references to the 3.x APIs (best
would be to remove them from your target!)
