Thanks for the input. This is what I suspected, and have already, as you guessed moved in that direction. I've just been struggling with the idea of moving all of the data-handling code out of the UI entirely, to the dataenvironmeent class.

>>I am writing a class that consists of an option group in a container. This option group asks the question All: Yes / No where a No answer brings up a moverlistpair form and allows the operator to select a list of values to include.
>>This option group will be the parent of a number of different children which will draw their options from a number of different sources. Up to this point the hosting form has held two arrays one for all values, and one for the selected values, but since its possible that the option group could occur more that once on a form (for instance all clients: Y/N and All Projects Y/N). I should also say that I'm using codemine which has a fully objectified data environment class.
>>My question is this: Where is the appropiate place to put an array that will be referred to by code outside the class? Does it obfuscate the code to place it in the option group?

>>TIA

>Since the selection may occur more than once on a form, I would create a class (Container) that includes your selection logic, including the All: Yes / No part, and the OptionGroup. It seems you already have this. The logical place to place the array(s) would also be in this same Container class, IMO.
