I have a tomcat based web application. It is mainly applet oriented.
The problem is with one of my applet which is having combo box placed in it (JComboBox). ToolTip text is set on that control. While running the application and moving the mouse over the control, I am getting the following error stack.

java.lang.Error: Destination component not connected to component tree hierarchy

Is it a bug with Java itself or I have to do anything to fix this.

Please help me out in this issue ???
