Checkbox in repeater, but default all to checked

Question

Hi, I've been over old messages trying to figure this out, but haven't found out how to do this 'so simple' thing.
I have checkboxes in a repeater that are dynamically created from a pulldown menu of options. The checkboxes are created when I click an "add" button which submits the selected option from the dropdown in the form to an update action, back to the form jsp. Basically the same page is displayed, but updated with selected documents from the dropdown which now appear as checkboxed data in a repeater.
All is well, as the checked items then go to an output page when the form submit button is pressed, and are diaplayed in another repeater on that page. What I want though is to have the checkboxes all be set to checked initially as they are created, so the user can uncheck something that was accidentally selected for submittal. I am using a hashmap to put the selected documents into, and the checkboxes in the repeater use a datasource which is a string array in the form bean. Can I set the default value to {(read the selection)} or similar? I can't get it to work. Does this all have to be a Boolean array like another post seems to allude to?
Alternativelty, what is actually desired, is to check items to be deleted instead of submitted, but that seems like much more work to make it pretty.
Thanks for any help.

Hi,
when you use an individual radio button the default check can be avoided.This can be acheived by creating three attributes.The 'Keytoselect' property must be unique for every radiobutton and the 'selectedkey' property must be a shared one.Then you can set value for 'Keytoselect' property to select a particular radiobutton.
When you want a particular radiobutton to be checked when loaded then following code can be used:
wdContext.currentContextElement().setSelected_Key_Att(wdContext.currentContextElement().setFirst_att);
