Master/Details Block not refreshing after delete [message #308788]

Hi all,
Can anyone let me know why am facing a problem stated below,

I have a Master/Details block , there is treeviewer that displays the
EMF model and there is details section that displays the Properties of
the selected model .

I have context menu that displays the New with the allowed child of the
Model element displayed in the Tree and other default context menus like
delete , undo etc.,

When i choose the model element its displaying the data correctly on my
details page. Now the issue starts when I right click selected model and
click delete , my model element in the Tree Viewer is deleted where in
my Details page still remains with the old data ?

Can anyone help how to over come that and make my details page disappear
once i delete the Model Element in the Tree .

I reffered to org.eclipse.pde.ui , but they had used the
IDetailsPageProvider , wherein I have a details page per master part.

Thanks.

Kamesh,

I assume that your details page responds to selection and that deleting
an object should cause a new selection so that new selection should
cause the details view to update. Note that in the generated EMF
editor, the command stack listener refreshes the properties view, so
maybe that's what you need to do:

commandStack.addCommandStackListener
(new CommandStackListener()
{
public void commandStackChanged(final EventObject event)
{
getContainer().getDisplay().asyncExec
(new Runnable()
{
public void run()
{
firePropertyChange(IEditorPart.PROP_DIRTY);

// Try to select the affected objects.
//
Command mostRecentCommand =
((CommandStack)event.getSource()).getMostRecentCommand();
if (mostRecentCommand != null)
{

setSelectionToViewer(mostRecentCommand.getAffectedObjects()) ;
}
* if (propertySheetPage != null &&
!propertySheetPage.getControl().isDisposed())
{
propertySheetPage.refresh();
}*
}
});
}
});
