Parable of David's Multi-coloured Checkboxes

Hi Chuck,
Thanks for the reply. The only table is a list of variables to hold
checkbox values.
T_Group
------------
pk id integer
member integer
isHappy integer
isFull integer
etc.
The labels are in html.
I guess what I am asking is where I can apply logic to the checkbox
bindings to make them correlate to a string binding? The label needs
to point to a variable value, not a value, if that makes sense.
Not at all, really.
i.e. for variable "member" display string related to member "The
group allows membership"
for variable "isHappy" display string related to isHappy "The group
is a happy group"
Please don't give me grief for my "parable" variables ;-)
Me? I would never do that!
I was thinking of something like a LabelledCheckbox component:
<wo:LabelledCheckbox name = "member" eo = "$aGroup" />
which would generate:
<wo:checkbox name = "member" value = "1" selection = "$selection" />
<wo:string value="$label" />
value comes from eo.valueForKey(valueForBinding("name")))
selection/setSelection wrap
eo.valueForKey(valueForBinding("name"))) /
eo.setValueForKey(newValue, valueForBinding("name")))
label finds the entity for T_Group, gets
entity.attributeNamed(valueForBinding("name")) and then pulls the
label text out of attribute.userInfo().valueForKey("label") if you
want it from the EOModel or uses
labelEO.valueForKey(valueForBinding("name"))) if you want it in the
database.
Is that making any sense?

Hi all,
I have a form with many wo:checkboxes. I would like to store the
labels for the checkboxes in the database instead of hardcoding
them in the html. Is there a way I can tie a specific checkbox to
a unique value in a table of labels? For example:
<wo:checkbox name = "member" value = "1" selection =
"$aGroup.member" /> <wo:string value= ??? />
I think you would want a custom component that contained this or
maybe the entire radio group? The component would have the logic to
find the label. I can't be more specific without knowing your
database setup.
