User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7b) Gecko/20040323 Firefox/0.8.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7b) Gecko/20040323 Firefox/0.8.0+

I've asked it here before:
http://groups.google.com/groups?dq=&hl=en&lr=&ie=UTF-8&oe=UTF-8&threadm=Qzybc.11361%24Y22.123711%40zonnet-reader-1&prev=/groups%3Fhl%3Den%26lr%3D%26ie%3DUTF-8%26oe%3DUTF-8%26group%3Dnetscape.public.mozilla.qa.editor

This returns true to me:
textarea.controllers.getControllerForCommand('cmd_insertText').supportsCommand("cmd_insertText");

But when I try to use it:
textarea.controllers.getControllerForCommand('cmd_insertText').doCommand('cmd_insertText','hallo');


I get an NS_ERROR_NOT_IMPLEMENTED back.

It seems like this is the source that's causing the trouble:
http://lxr.mozilla.org/seamonkey/source/editor/libeditor/base/nsEditorCommands.cpp#711



Reproducible: Always
Steps to Reproduce:
1. Tried to use doCommand('cmd_insertText','hallo');
2.
3.

Actual Results:  
I got an NS_ERROR_NOT_IMPLEMENTED back.
 

Expected Results:  
It should work (preferrably) or the supportsCommand("cmd_insertText") should
return false.

Attachment: Small testcase to show the problem

Click on the two buttons.
You should click yes on the security warning.
After clicking the first button, you get returned 'true'.
But after clicking the second button, you get an error in the javascript
console.

The testcase needs to be downloaded and tested locally to see the bug.
