Re: Gwt Binder problem.

DockLayoutPanel center element holds only one panel. Wrap your
veritcalpanels in another verticalpanel. See the sample below.

//corrected code .xml file.

<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'>
<g:DockLayoutPanel>
<g:north size="25">
<g:FlowPanel>
<g:Label>Good</g:Label>
</g:FlowPanel>
</g:north>
<g:center>
<g:VerticalPanel ui:field="v">
<g:VerticalPanel ui:field="panel1">
<g:Button ui:field="button1">North</g:Button>
<g:Button ui:field="button2">South</g:Button>
</g:VerticalPanel>
<g:VerticalPanel ui:field="panel2">
<g:TextArea ui:field="greenText" />
</g:VerticalPanel>
</g:VerticalPanel>
</g:center>
</g:DockLayoutPanel>
</ui:UiBinder>
