Hi,
It's possible that the "Delete" operation actually triggers several commands in your case, e.g. one for the deletion of the element and refresh of the diagram, and then someone reacts to the deletion with another change.
In this case your "Undo" would only apply to the second command and not to the deletion.
This might depend on the actual modeler you use if it does some non-standard things.
I just tested the basic scenarion on Ecore Tools (which is based on Sirius), and it works with a single Ctrl-Z.
After you've deleted the element, look at the "Edit" menu in the window's menu bar. It should mention "Undo Delete element (Ctrl-Z)". If it does not, then something has executed another command in reaction to the delete, and you may need several "Undo" operations to actually undo the delete.

Dear Pierre-Charles:
Thank you for your quick reply. According to your hint, I found the problem is in RCP. In RCP application, I create "Edit" menu through Extensions.
<menu
label="Edit">
<command
commandId="org.eclipse.ui.edit.undo"
id="undo"
label="Undo"
style="push">
</command>
<command
commandId="org.eclipse.ui.edit.redo"
label="Redo"
style="push">
</command>
I guess I missing something in code. If realize "Edit" menu in code ApplicationActionBarAdvisor:
@Override
protected void makeActions(IWorkbenchWindow window) {
undo = ActionFactory.UNDO.create(window);
redo = ActionFactory.REDO.create(window);
}
@Override
protected void fillMenuBar(IMenuManager menuBar) {
editMenu = new MenuManager("&Edit", IWorkbenchActionConstants.M_EDIT);
menuBar.insertAfter("file", editMenu);
editMenu.add(undo);
editMenu.add(redo);
}
Undo can works correctly.
