Say that I have an NSTableView with two columns, firstName and lastName. Say that some marketing hack insists that I store these combined as one string.

For the last hour, I've been trying to figure out how to bind two table columns such as this to a single string in storage, bidirectionally, using Cocoa bindings. But I keep running into a wall, trying to transform two objects into one. What's the smart way to do this?
Thanks,
Jerry Krinock


just a guess, and i haven't tried this....

bind both columns to the same entity field, but use different value transformers for each column.
