Uibinder for drag and drop

[lmcadory]

Hopefully this isn't a dumb question.

I wanted to know how to use droptarget with uibinder? I'm trying to combine the borderlayout uibinder example with the basic dnd example. I trying to place the dragable items to the center layout and make the west layout the droptarget. I'm very new to uibinder and am having trouble. I imported the package the holds DropTarget and just added it under the west layout under the SimpleContainer like so:

<container:SimpleContainer>
   <container:child layoutData="{outerData}">
     <container:BorderLayoutContainer ui:field="con" borders="true">
       <container:north layoutData="{northData}">
         <gxt:ContentPanel />
       </container:north>
       <container:west layoutData="{westData}">
         <dnd:DropTarget /> 
         <gxt:ContentPanel />
       </container:west>
       <container:center layoutData="{centerData}">
         <gxt:ContentPanel headingText="BorderLayout UiBinder Example" resize="false">
           <g:FlexTable />
         </gxt:ContentPanel>
       </container:center>
       <container:east layoutData="{eastData}">
         <gxt:ContentPanel />
       </container:east>
       <container:south layoutData="{southData}">
         <gxt:ContentPanel />
       </container:south>
     </container:BorderLayoutContainer>
   </container:child>
 </container:SimpleContainer>

When I run it, it doesn't build anything. Is it even possible to use droptarget in uibinder?

I figured it out. I had to had another container, one for the source and one for the droptarget. I removed the DropTarget from the container. That didn't do anything.
