title: GWT Accessing Widget Methods without knowing the name of the Widget
body: <p>This may have been asked before but I have no idea how to word it to search for it.</p>
  
  <p>I have a composite widget that has methods to update some of the widgets that make up the composite widget. When I add this composite widget to my panel I use a do while loop to pull data from an XML file and populate the composite data. When I instantiate the object each time to add the data it has a scope local to the do-while loop and I cannot call methods to update the data in the composite widget later on. Is there maybe a way to make an array of these composite widgets or another solution to be able to access the Widget?</p>
