When the child controls of Panel control be activated or inactivated, the Panel control will always re-draw the child controls, and do not call the child controls's draw method to generate the DOM element of the control.
So we can not add some controls with complex UI to the Panel control, such as MapTypeControl. See the ticket #2421 <http://trac.openlayers.org/ticket/2421> Li XinGang EMail: slinav...@gmail.com Blog: avlee.cnblogs.com Site: www.mapboost.org
