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.
