Why does UIWAIT throw a warning message when used with Popup menu?

UIWAIT does not seem to properly handle popup menus that are defined using the “|” separator.

The following code is used to declare strings in a popup menu:

v = 'Menu Item 1|Menu Item 2';

set(handles.ActiveSelector, 'String', v);

The following warning is obtained when UIWAIT is used with the above popup menu (that is defined using the “|” separator):

 Warning: popupmenu control requires that Value be an integer within String range

 Control will not be rendered until all of its parameter values are valid.

There is a bug in MATLAB 7.0.4 (R14SP2) in the way the popup menu string is parsed prior to rendering this UI control in a Java figure.

To work around this issue, use cell arrays to declare strings in the popup menus.

Declare the strings for the popup menu using the following syntax

v = {'Menu Item 1','Menu Item 2'};

which does not result in an error.
