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.

private void createLabel( Composite parent, String content )
	{
		Label label = new Label( parent, SWT.NONE );
		if ( content != null )
		{
			label.setText( content );
		}
		setLabelLayoutData( label );
	}
	private void setLabelLayoutData( Label label )
	{
		GridData gd = new GridData( );
		if ( label.getText( ).equals( LABEL_VALUES ) )
		{
			gd.verticalAlignment = GridData.BEGINNING;
		}
		label.setLayoutData( gd );
	}
	private void addCheckBoxListener( final Button checkBox, final String key )
	{
		checkBox.addSelectionListener( new SelectionAdapter( ) {
			public void widgetSelected( SelectionEvent e )
			{
				checkBoxChange( checkBox, key );
			}
		} );
	}
