Public members vs. Parm methods on classes extending SysAttribute in AX 7

I thought I did the right thing when I changed attribute classes that I moved into AX 7 from AX 2012, so they had public members instead of Parm methods.

Well, don't do that. As it turns out the attribute framework is looking for the Parm methods when trying to apply the member values. If you don't have them, the values are not being set.

Hopefully this information can save you an hour or so of tedious debugging.
