Error #2007 in TUIO.as about touchlib HOT 4 OPEN

This is a namespace conflict correct? flash.events.TouchEvent is a standard 
flash event 
as of the new Flex SDK beta? I fixed things by moving and renaming the whole 
package to 
"tuio.events.*"

i got that error (#2007) when tried to run my swf on a web browser from a 
server.

i think the problem is the host, although the error is thrown when i add a 
touchEvent 
listener:

try
{
    addEventListener ( TouchEvent.MOUSE_DOWN , someFunction );
}
catch ( error:Error )
{
    stageAddedTextField.text = error.message;
}

// the textfield will show: error #2007
}

I had the same issue and resolved by changing the package name from 
flash.events to TUIO.events

What is the process in changing the package name?
