Bug 177439 Need an easy way to determine default value for a dynamic parameter
Currently, I have to bring up the data set editor, preview the results in the data set and make a mental note of the value to use for a report parameter that depends on a data set. It would be nice to have a drop down on the default value field, such as <Select value> which when selected queries the data set and presents me with a list to select from.

			controlTypeChooser.setItems( choices );

			{
				controlTypeChooser.setText( getInputControlDisplayName( ) );
			}

			{
				int index = controlTypeChooser.indexOf( originalSelection );
				if ( index == -1 )
				{
					
					controlTypeChooser.select( 0 );
					return true;
				}
				controlTypeChooser.setText( originalSelection );
			}
