FULL PRODUCT VERSION :
java version "1.5.0_04"
ADDITIONAL OS VERSION INFORMATION :
Windows XP
Windows 2000
Windows 2003
A DESCRIPTION OF THE PROBLEM :
In a page like:
<div style='display: block'>
<applet ... >
</div>
<div style='display: none'>
<applet ...>
</div>
<div style='display: none'>
<applet ...>
</div>
When any subsequent <DIV> is shown, and the first one is hidden, the applet within the <DIV> doesn't repaint properly the first time it is shown. You still see the first applet on the screen, even though you should be seeing the second one.
I tried with both Applet and JApplet subclasses, but the behavior was the same both times.
This behavior worked in 1.4.1, but it no longer working in the latest 1.5 version.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
With the attached HTML page and Java applet code:
1) In the HTML window, click on the Applet 2 button.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When you click the Applet 2 button, you should see an applet with a label saying Second Applet.
ACTUAL -
You still see an applet with a label saying First Applet.
If you click on the "Applet 1" button and then on the "Applet 2" button again, you will see the proper applet.
