PageContainer.selectChild's second argument never used

[guest]

​PageContainer's selectChild(/*Widget*/ page, /*Widget*/ callingWidget) method never uses the second argument to the call as far as I can tell. It just assigns callingWidget to this.correspondingPageButton, and this.correspondingPageButton is seemingly never used again in the code.

	selectChild: function(/*Widget*/ page, /*Widget*/ callingWidget){
		// summary
		//	Show the given widget (which must be one of my children)
		page = dojo.widget.byId(page);
		this.correspondingPageButton = callingWidget;

		// Deselect old page and select new one
		if(this.selectedChildWidget){
			this._hideChild(this.selectedChildWidget);
		}
		this.selectedChildWidget = page;
		this.selectedChild = page.widgetId;
		this._showChild(page);
		page.isFirstChild = (page == this.children[0]);
		page.isLastChild = (page == this.children[this.children.length-1]);
		dojo.event.topic.publish(this.widgetId+"-selectChild", page);
	},

Just wondering why there's a second argument if it does nothing. For future use? Intended for inclusion in the published events?

Drat, looks like I missed tacking rhys@… as the email for that ticket.

(In [8814]) Remove unused parameter from selectChild(). Fixes #2763.
