Bug 182677 Crosstab can not be converted to template item
The logic in model to check if crosstab can be converted to template report item returns false, but it should be true. The related check code is at DesignElementHandle.canTransformToTemplate().
model/org.eclipse.birt.report.model/src/org/eclipse/birt/report/model/core/ContainerContext.java
if ( focus.getElement( ).isVirtualElement( )
					|| focus.getElement( ).getExtendsName( ) != null )
				return false;
			
			ContainerContext containerInfo = this.focus;
			while ( containerInfo != null )
			{
				DesignElement container = containerInfo.getElement( );
				if ( container instanceof ListingElement
						|| container instanceof MasterPage )
				{
					List errors = container.checkContent( module, this.focus,
							defn );
					return errors.isEmpty( );
				}
				containerInfo = container.getContainerInfo( );
			}
			return retValue;
