FULL PRODUCT VERSION :
java version "1.5.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b32c)
Java HotSpot(TM) Client VM (build 1.5.0-beta-b32c, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Windows 2000 5.00.2195 Service Pack 4
A DESCRIPTION OF THE PROBLEM :
This scenario has not worked since 1.3....
I load an applet in a frame and upon submission by the user, the applet does the following to show a new document:
UrlOnError = false;
try{
userUrl = new URL(getCodeBase().toString() + "new.cgi?" + Key);
}
// You MUST try-catch this method.
// If it is still wrong then we'll show an error message too.
catch (Exception e){
UrlOnError = true;
}
getAppletContext().showDocument(userUrl,"_self");
In 1.5, the URL replaces "_top" instead of "_self"
REPRODUCIBLE TEST CASE :
-------------------Frame1.html-------------------
<HTML><HEAD></HEAD><BODY>
<center>Compiled under 1.5.0 on Windows 2K<br/>
Frame 2's applet resides in a DIV and Frame 3's applet resides in the document body.<br/>
<b>For Internet Explorer 6.0 Running 1.5.0:</b><br/>
When we perform a <b>getAppletContext().showDocument(userUrl,"_self")</b> on Frame 2, _top gets replaced.<br/>
Frame 3 works properly only from the document body.<br/>
<b>For Internet Explorer 6.0 Running MS VM:</b><br/>
Response is as expected on both frames: Frame 2 acts just like Frame 3.<br/>
<b>For Netscape 7.2 Running 1.5.0:</b><br/>
Absolutely no response from the button clicks!<br/>
</center>
</BODY></HTML>
-------------------Frame2.html-------------------
<HTML><HEAD></HEAD>
<SCRIPT LANGUAGE="JavaScript">
function doApp(){
v='<center><br/>FRAME 2<br/>Click the button and this frame <b>incorrectly</b> refreshes to "_top" instead of "_self" <b>ALWAYS</b>.<br/>'
v+='This applet resides in a <b>DIV</b>.<br/><br/>'
v+='<applet code="testShowdoc.class" width=500 height=120 >'
v+='<param name=newURL value=frame2>'
v+='</applet></center>';
document.getElementById('div02').innerHTML = v;
}

userUrl = new URL(getCodeBase().toString() + "Frame2.html");

}
}
Load an applet in a frame and
getAppletContext().showDocument(userUrl,"_self");
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expected that the frame would be the target of the URL and not _top.
ACTUAL -
_top became the target and the browser's top frame was replaced with
the response of the url.
REPRODUCIBILITY :
This bug can be reproduced always.
