[Chameleon] How to dynamically load a widget

[Yahya Mohammad]

Hi all,
I created a custom widget and want it to show up only when a certain GET 
parameter is passed initially in the application URL. I tried changing the 
DrawPublish function like this: 

function DrawPublish()
{
	if (strtoupper($this->getVar('MYVAR')) == 'MYVALUE') {
		return $this->moButton->DrawPublish();
	} else {
		return '<!-- MYWIDGET widget hidden -->';
	}
}

This works pretty well, except that the javascript functions I defined in 
GetJavascriptFunctions still show up on the page. Is there a better way to do 
this?
