Using checkboxes and/or radio buttons in a "portal context"
I'd like to be able to use a checkbox or radio button set to specify a "default" entry in a portal.
For example, I have a membership database, and in a member record, I show a portal of his/her addresses. Since each member can have multiple addresses, I'd like the user to check a box/radio button to specify which of the addresses shown in the portal is the default address for that member. Easy enough to add a checkbox field... However, I'd like this checkbox to act like radio button sets, where you can only have one checked at a time. The problem is that the context of a radio button set is a record and I want it to be the portal, so I can have one checkbox per record and have them automatically clear if I select a different record in that portal.
Thanks for any help,
