I've just started really taking advantage of the member data stuff for a new class I'm working on. It's got a little under 80 PEM's. I tend to actually make my PEM's descriptive, so they have longer names like "nTotalAmountToGoal" or "GetPriceSchedule". I've also added them to the Favorites tab so it's easy to see them (eg. they're not mixed in with the VFP methods). I just got an error when I added a new property, "The member data for this class is over 8K in size, which is too long, so the display and favorite settings won't be saved".
WTF?! Do you know how often someone is likely to run into this as soon as you really try to leverage the member data settings? I haven't even tried using this data to extend anything yet and I've already run into this.
Arg...
BTW - because of this limit, they REALLY should have shortened the tag names; the "memberdata", "favorites", "display", "method", "property", and "name" are taking up a whopping 37% of the entire XML string length.
