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

	 * based on the given content element and add it to the report design first.
	 * Then, let the created template element refer the added template parameter
	 * definition.

	 * @param base
