From some googling it appears that, at least in the release candidate for NET2 this was a known bug; only binding to Data Sources lets those dictionaries be populated. | | From some googling it appears that, at least in the release candidate for NET2 this was a known bug; only binding to Data Sources | lets those dictionaries be populated. 2) I think it's weird that the "value" capability is tied to the parameters collection.
