Load the included the following html Firefox, click button ‘Init Child’ more than 2 times, click on the ‘Back’ on the tool bar once, then clicks either ‘Call Child’ or ‘Call Child’ cause firefox to issue ‘Permisson denied to get property Window.func’ exception.
Please not, if the the 'Back' button had not been clicked, both function calls (either from parent to child or child to parent) would work.
the test html:
<html>
<head>
<script type='text/javascript'>
var count=0;
function initchild() {
count++;
var iframeWin = frames['iFrame'];
var iframeDoc = iframeWin.document;
var newDoc=iframeDoc.open("text/html")
var txt = "<html><head>";
txt += "<script type='text/javascript'>";
txt += "function func() {alert('called from parent "+count+"');}";
txt += "function callParent() {parent.func("+count+");}";
txt += "<\/script>";
txt += "</head>";
txt += "<body>";
txt += "<input type='button' onclick='callParent()' value='Call Parnet" +count+"'>";
txt += "</body></html>";
newDoc.write(txt);
newDoc.close();
}
function func(c) {
alert("called from child "+c);
}
function callchild() {
var iframeWin = frames['iFrame'];
iframeWin.func();
}
</script>
</head>
<body>
<iframe id='iFrame' name='iFrame'></iframe>
<br /><br />
<input type='button' onclick='initchild()' value='Init Child'>
<br /><br />
<input type='button' onclick='callchild()' value='Call Child'>
</body>
</html>
I try the same html in IE (version 6.0.2600.0000.xpclient.010817-1148), everything works fine.
Reproducible: Always
Steps to Reproduce:
1. copy the test html text to a file
2. load the file to Firefox
3. click the 'Init Child' button twice
4. click the 'Back' button once
5. open the 'Javascript Console' from the 'Tools' menu
6. click on the 'Call Child' button, the console should show 'uncaught exception: Permisson denied to get property Window.func'
7. click on the 'Call Parent1' button, the console should show 'uncaught exception: Permisson denied to get property Window.func' again.
