Viewing pixel values in survey mode.

Question

Hi,
In the Develop module, the histogram displays pixel values, updating dynamically as you mouse around over the an image in the preview area. Is there a way to enable this behavior in the Library module? Specifically, I'd like to be able to compare the pixel values of two or more images displayed in survey mode. Thanks,
kobi

Here is a piece of code I use:
CREATE OR REPLACE PROCEDURE sm_list AS CURSOR emp_cursor IS
SELECT d.department_name,
e.last_name
FROM departments d,
employees e
WHERE d.department_id = e.department_id;
emp_record emp_cursor % rowtype;
BEGIN
FOR emp_record IN emp_cursor
LOOP
DBMS_OUTPUT.PUT_LINE(emp_record.last_name);
END LOOP;
END;
With this example, I agree, the smart data is null. Logged a bug. However, note that I do see values in the data tab and can modify and watch these values.
When using cursors I've been looping and then fetching into cursor records, i.e.:
FETCH emp_cursor
INTO emp_record;
emp_tab(i) := emp_record;
and then the values display in the Smart data and data tabs.
