I use this code to disable all ui components. All workes eccept for one table. Putting a Breakpoint at the end of the function and checkig the Enable attribute of that table showes that it is 'off'. When I resize the window the display updates and the table shows grayed.

The same thing happens after I enable all the ui components. I tried to refresh the figure, I also tried to call figure(), none worked. Any idea what might cause the problem and how can I fix it?

        function DisableApp(app, hExceptFor)
            Child = findall(app.MyApp);
            N = length(Child);  
            for i= 1 : N
                if isprop(Child(i),'Enable')
                    set(Child(i), 'Enable', 'off');
                end
            end
            if nargin == 2
                M = length(hExceptFor);
                for i= 1 : M
                    if isprop(hExceptFor(i),'Enable')
                        set(hExceptFor(i), 'Enable', 'on');
                    end
                end
            end
        end

First, this is not the best approach to disabling all components. Two alternatives that are much simpler and offer easier control are,

Create a uipanel that contains all of the app components you want to toggle on/off. Then, just toggle the uipanel's enable property.
Use a uiprogressbar with the indeterminate option to disable the entire app until progress is resummed programmatically or manually.

About the problem with the uitable, it's not clear what you're seeing vs what you expect to happen. Maybe a screenshot would help. If you want the table to completely disappear, set its Visible property rather than its Enable property.
