When you use the Vwa.VwaPage.getPosition function in JavaScript to return the position of a page in Microsoft SharePoint Server 2010, Vwa.VwaPage.getPosition returns the same value regardless of the position of the page in the view port. The function always returns the following value:

(-viewSize.width/2, -viewSize.height/2)


Programmers can work around this issue by accessing internal objects to calculate the expected result. For example, programmers can use code that resembles the following:

var viewPosition = vwa._control._renderingArea.getViewPosition();
var viewSize = vwa._control._renderingArea.getViewSize();
var pagePosition = {};
pagePosition.x = viewPosition.x - Math.ceil(viewSize.width / 2);
pagePosition.y = viewPosition.y - Math.ceil(viewSize.height / 2);


Microsoft has confirmed that this is an issue in the Visio Services API.
