Summary: unable to redraw dynlayer object in IE 6.0

Initial Comment:
layer2 is a dynlayer object which is already a children of 
dynlayer object layer1. The following redraw logic does 
not work in IE 6.0

layer2.removeFromParent();	 
layer1.addChild(layer2);

Below is the error message:

Line: 51
Char: 4
Error: invalid argument
Code: 0
URL:  http://127.0.0.1/test.html

Hi.  It was Andrew (agillett) who changed Resolution to
Works for Me, before the example was supplied.  Now I see
the problem as you describe.

========
In Firefox, if reload, I get this error in the JavaScript
console:

Error: this.parent.menu.OnLoadDesktop is not a function
Source File:
file:///path/to/dynapi-3.0.0-beta2/examples/test/content.html
Line: 22

If I then hold Shift and reload, I get this JavaScript error:

Error: this.parent.menu.OnUnloadDesktop is not a function

But the page loads properly otherwise.

This indicates that something is being destroyed and then
trying to use it after it's gone.

========
In IE 6, on pressing Set Desktop, I get a different error
from the one reported.  In an alert-style popup, in addition
to the script error popup:

An error has occured in this dialog.

Error: 84
Unspecified error.

And the odd thing, the IE script error popup has no content:

Line: 
Char: 
Error: 
Code: 
URL: 

But clicking "OK" on the alert-style popup closes the IE
script error popup as well.

Reloading the page AFTER clicking Set Desktop yields the
following script error:

Line: 198
Char: 19
Error: Can't execute code from a freed script
Code: 0
URL: file:///path/to/dynapi-3.0.0-beta2/examples/test/menu.html

Followed by:

Line: 22
Char: 4
Error: Object doesn't support this property or method
Code: 0
URL:
file:///path/to/dynapi-3.0.0-beta2/examples/test/content.html

Then the page reloads just fine.

I'll have to look into it some more.

First, thanks a lot for checking this problem. 

Your test code does work. To reproduce my problem, please 
unzip my attached file and put it in "test" folder under the 
dynapi's "examples" folder. "desktop.html" is the entrance 
page. Please follow steps below to see the problem:

==========================================
Problem for IE6:

Step 1: browse page: "desktop.html" and remember what's in 
the the lower frame of the screen.

Step 2: click "Set Desktop" button to redraw the lower frame 
of the screen. You can see how the yellow layer and blue 
layer disappear.

==========================================
BTW, I just found another problem for the same code when 
running it in firefox 1.0.1. Below are the steps to reproduce 
the problem:

Step 1: browse page: "desktop.html" and remember what's in 
the upper frame of the screen.

Step 2: click the browser's "reload" button to refresh the page.
You'll see that "toolbar1" disappears

Also, let us know what specific version of DynAPI you are
using.  I did not see the problem with dynapi-3.0.0-beta2. 
So provide a complete example of the failure, and the DynAPI
version you're using.

I haven't been able to reproduce this error. My test case is
http://dynapi.sourceforge.net/releases/dynapi3x/test/006.Redraw.html

Can you supply the complete code for your example that fails?
