Source Fields Never Load in Update/Insert Block
I am creating a mapping between a MySQL database (source) and Microsoft Dynamics (target). When I open up the Update/Insert Block to map the fields, I get loading messages for both the source and target fields but I only ever see the target fields. The source fields are not displayed. I know that I can access the source as I have tested the connection and the data appear in the Preview of the Query Block. Any help would be appreciated. Thanks.
