[Name] dropListener [Type] javax.el.MethodExpression [Supports EL?] Only EL [Description] 
A method reference to a callback with the signature oracle.adf.view.rich.dnd.DnDAction method(oracle.adf.view.rich.event.DropEvent dropEvent) called when a drop occurs on the component. Since the panelDashboard will automatically adjust the positions of its children in the browser, this method should return DnDAction.NONE if your handler is successful in adjusting the position of the reordered children since this will cause the panelDashboard to be left as is. If you return DnDAction.MOVE, the panelDashboard will be redrawn. You may wish to use org.apache.myfaces.trinidad.change.ReorderChildrenComponentChange and ChangeManager().addComponentChange() if you wish to preserve a new ordering of the children. Ideally, you should use an MDS ChangeManager to persist the change longer than the user's session so that the use does not have to repeatedly make the same reorder gesture every time your application is used. The dropEvent.getDropSiteIndex() method will give you the location that the user desires the dragged component to end up at. Use dropEvent.getTransferable().getData(DataFlavor.UICOMPONENT_FLAVOR) to get the dragged component.
