I'm writing a replacement for the "Generate Table Layout" button on the BizForm layout editing page, and to get all the information I want, I'd like to parse the bizform's definition. My first attempt was (roughly) this:

BizFormInfo bfi = BizFormInfoProvider.GetBizFormInfo(bizFormId);
stringToParse = bfi.Form.GetXmlDefinition();

But it turned out that if I changed the fields on the bizform (by adding or deleting a field, or any other change), the definition string contained an old version. So I changed my method to this:

BizFormInfo bfi = BizFormInfoProvider.GetBizFormInfo(bizFormId);
DataClassInfo dci = DataClassInfoProvider.GetDataClass(bfi.FormClassID);
stringToParse = dci.ClassFormDefinition;

And that works. DataClassInfo.ClassFormDefinition contains current info, while BizFormInfo.Form.GetXmlDefinition() doesn't.

Is that supposed to be the case? Or is there some method of BizFormInfo I could call which would force it to flush its cache? TouchKeys() didn't seem to do anything.
