Dynamic List of Checkboxes and their Default Values

Question

Hello,
I have spent more than five hours feebly attempting to figure out how to make a dynamic list of checkboxes (using an LOV) adhere to the values in the database which those checkboxes represent. The LOV itself works; I can get a nice list of checkboxes with the appropriate names, but I can't get HTML DB to check the boxes that have a value of 'Y' in the database. The code for my LOV follows:
SELECT mesg_name n, mesg_id r
FROM notifications
WHERE mesg_id = (SELECT mesg_id
                  FROM subscriptions
                  WHERE upper(network_id) = upper(:APP_USER))Since this is a dynamic list of checkboxes, I obviously cannot use the "Label" property to set the labels of each checkbox. That is what n is in the query above. r is the unique ID of the message (a varchar2) that I will need to pass back to the program after the page is submitted by the user for processing. I cannot take up the value field of the checkbox with a "Y" or something as equally vague. The ID of the subscription that the user is subscribing to or unsubscribing to must be passed back to the program so the appropriate modifications to the database table can be made.
I would most appreciate it if anyone could lend assistance.
Thank you,

Marc,
I think I see what you're trying to do. You'll have to separate process that renders the LOV as a series of check boxes from the process that sets the checked values for each user.
Before the LOV is rendered on a page, make sure you set the session state value of the LOV item to a colon separated set of IDs based on your query:
SELECT mesg_id
FROM subscriptions
WHERE upper(network_id) = upper(:APP_USER)
If you have trouble, let me know, I'll try to come up with an example.
