Bug 114903 Default values are not shown in Show Report Parameters' dialog
Description: Default values are not shown in Show Report Parameters' dialog Steps to reproduce: 1. Create several report parameters, only set default value for them. 2. Drag them to Layout 3. Preview and click Show Report Parameters button. Expected result: Default values are shown in value box, so I can modify the parameter which I want to change. Actual result: In Enter Parameters dialog, all values were empty, I just wanted to modify one parameter and found that I had to input all values.
