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
IElementDefn defn = MetaDataDictionary.getInstance( ).getElement(
					ReportDesignConstants.TEMPLATE_ELEMENT );
			if ( element instanceof TemplateElement )
				return canContainTemplateElement( module, defn );
			ContentIterator contents = new ContentIterator( module, element );
			while ( contents.hasNext( ) )
			{
				DesignElement content = (DesignElement) contents.next( );
				if ( content instanceof TemplateElement )
					return canContainTemplateElement( module, defn );
			}
			return true;
