GUI refresh problem in java 1.6
I'm developing a web based application using RMI Interface. Recently I have upgraded my java version from 1.4.02 to 1.6.0.07. But after that I started to have some refresh problems in GUI. Espcially on the panels that have jtable. The list on the table got lost when I open another window on it. Then all data come back when I click on the table. Nothing has been changed in the source code. Only the java is upgraded. Does anyone have any opinion about the cause and hopefully for the solution. Any idea will be very helpful.
Thanks in advance!
