There can be one single widget inside the <g:Center> tag. You are
using two VerticalPanels inside the center tag. To solve the problem
use another verticalpanel wrap(v1+v2).

//Try the below code   corrected .xml file.

<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
        xmlns:g='urn:import:com.google.gwt.user.client.ui'>
        <g:DockLayoutPanel ui:field="dock">
             <g:north size="25">
                  <g:FlowPanel>
                      <g:Button ui:field="save">Save</g:Button>
                  </g:FlowPanel>
             </g:north>
            <g:center>
               <g:VerticalPanel ui:field="V1">
                     <g:VerticalPanel ui:field="panel1">
                           <g:Button ui:field="button1">print</
g:Button>
                           <g:Button ui:field="button2">clear</
g:Button>
                     </g:VerticalPanel>
                     <g:VerticalPanel ui:field="panel2">
                           <g:TextArea ui:field="textArea" />
                      </g:VerticalPanel>
               </g:VerticalPanel>
             </g:center>
        </g:DockLayoutPanel>
</ui:UiBinder>
