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/command/TemplateCommand.java
private void createTemplateFromDesignElement( TemplateElement template,
			DesignElement base )
	{
		assert base instanceof ReportItem || base instanceof SimpleDataSet;
		assert template != null;
		assert module instanceof ReportDesign;
		
		
		try
		{
			TemplateParameterDefinition templateParam = new TemplateParameterDefinition( );
			module.makeUniqueName( templateParam );
			
			PropertyCommand propertyCmd = new PropertyCommand( module,
					templateParam );
			if ( base instanceof SimpleDataSet )
				propertyCmd.setProperty(
						ITemplateParameterDefinitionModel.ALLOWED_TYPE_PROP,
						DesignChoiceConstants.TEMPLATE_ELEMENT_TYPE_DATA_SET );
			else
				propertyCmd.setProperty(
						ITemplateParameterDefinitionModel.ALLOWED_TYPE_PROP,
						base.getElementName( ) );
			ContainerSlot defaultSlot = templateParam
					.getSlot( ITemplateParameterDefinitionModel.DEFAULT_SLOT );
			assert defaultSlot != null;
			
			DesignElement defaultElement = null;
			defaultElement = (DesignElement) base
					.doClone( CopyForTemplatePolicy.getInstance( ) );
