Might you add a new feature to wwBusiness, with a option flag, so that after a Load() it would iterate over all the string properties and do Alltrim() to them.
Is it reasonable to have to bus object framework clean up the BO (trim the whitespace) like this? I mean, are there time when you’d WANT this messy whitespace on the end?
At least by having an option flag, each user of the framework could opt-in to this feature.
