cannot use Drag Create example

[vadirajpg]

While trying to implement Drag Create sample as shown in the ShowCase, I am unable to add DragPiece object to a HorizontalPanel.

HorizontalPanel hp = new HorizontalPanel();
hp.add(new DragPiece("cube_blue.png", "b"));

There is a runtime exception. I could see the below error message in the Browser console.
Uncaught Type error: Cannot read property "Create" of Undefined at the line - var widget = $wnd.isc[scClassName].create(config);

Img.java

protected native JavaScriptObject create()/*-{
var config = this.@com.smartgwt.client.widgets.BaseWidget::getConfig()();
var scClassName = this.@com.smartgwt.client.widgets.BaseWidget::scClassName;
var widget = $wnd.isc[scClassName].create(config);
if ($wnd.isc.keepGlobals) this.@com.smartgwt.client.widgets.BaseWidget::internalSetID(Lcom/google/gwt/core/client/JavaScriptObject;)(widget);
this.@com.smartgwt.client.widgets.BaseWidget::doInit()();
return widget;
}-*/;

It looks like you are trying to mix GWT and SmartGWT components. This won't work well in general (see FAQ) and definitely will not work for drag and drop without a lot of additional code to map between the SmartGWT and GWT drag and drop systems (which are totally separate). Use the same widgets you see in the sample instead.
