Bug 148761 Unable to copy a report item from template to report
Steps: 1. Create a template, add a Text item "t1" or others 2. Create template item using "t1" 3. Double click the template item and we get a report item again. 4. We copy the item, paste to another report file. Expected: the text item can be copied. Actual result: Nothing happened, not copied and no error msg.

* resolved reference points to an the "target" element itself. An unresolved
 * reference gives only the name of the target element, and the element itself
 * may or may not exist. This allows the model to handle designs that refer to
 * template elements that have since been removed or renamed.
 * <p>
 * Elements that contain properties of this type must provide code to perform
 * semantic checks on the reference property. This is done to avoid the need to
 * search the property list to find any properties that are of this type.
 * <p>
 * The reference value are stored as an <code>ElementRefValue</code>
 * 
 * @see ElementRefValue
