show popup instead of creating new one in html dom

[smerny]

i have the following code:

	if(!helpPopup){
	    var helpPopup = new Ext.Panel({
	    	id: 'helpPopup',
			floating: params.floating,
			modal: params.modal,
			centered: params.centered,
			width: params.width,
			height: params.height,
			styleHtmlContent: params.styleHtmlContent,
			scroll: params.scroll,
			html: params.html,
			dockedItems: [{
			      dock: 'top',
			      xtype: 'toolbar',
			      title: params.title
			}]
		});
	}
	    
	helpPopup.show('pop');

i was expecting it to create the popup only if it hadn't previously done so... instead, everytime i close/reopen it is creating a new helpPopup div in the dom. how do i stop this?

nevermind, fixed it this way..

Demo = new Ext.Application({....

	if(!Demo.helpPopup){
	    Demo.helpPopup = new Ext.Panel({
	    	id: 'helpPopup',
			floating: params.floating,
			modal: params.modal,
			centered: params.centered,
			width: params.width,
			height: params.height,
			styleHtmlContent: params.styleHtmlContent,
			scroll: params.scroll,
			html: params.html,
			dockedItems: [{
			      dock: 'top',
			      xtype: 'toolbar',
			      title: params.title
			}]
		});
	}
	    
	Demo.helpPopup.show('pop');
