I am using a web application that build on java applet there is Jtree Object when I using the Property tool to get the wItemCount & wFocus there is an error - Error: An error occurred. ...
I am guessing that you have mapped your tree control to the standard Swing JTree control by using the Object Mapping feature. The problem is that your tree control is not derived from the JTree control and, therefore, is incompatible with it.
Please let me know exactly what tree control you have. Tell me the value of its 'JavaFullClassName' property.
