I am not sure if my issue is with qx.bom.element.Attribute.set() or that the HTML element that I am trying to update is in HTML that is in a qx.ui.basic.Label that is in a popup window? Basically, I have a series of wizard windows that get their content from HTML pages on disk. When using the pages there is some updating of elements I need to do, but no matter how I try and change the values of a div, the screen does not show the change. If you query the DOM, the change is made but not displayed. How can I force the change to be displayed?
