Here is an idea which seems to work, but needs more evaluation. What if you
named the form object with the property path in the form data? Even if periods
are not allowed (they seem to be), another character could be used. I think the
maximum length of an object name is 255 characters which should be plenty.
Here is an example. I created a form with one in input and the object method
below. The form object name is "some.property.path" and the expression is
Form.some.property.path.
Case of
: (Form event code=On Load)
Form.some:=New object
Form.some.property:=New object
Form.some.property.path:="TEST 123"
: (Form event code=On Data Change)
C_TEXT($name)
C_COLLECTION($cPath)
C_OBJECT($object)
$name:=OBJECT Get name(Object current)
$cPath:=Split string($name;".")
$object:=Form
For each ($name;$cPath.slice(0;-1)) //All except last element to get the
object.
$object:=$object[$name]
End for each
$name:=$cPath.pop()
$object[$name]:=Uppercase($object[$name])
End case
