I am wanting to use RE Exports for Export profiles in IOM, but it doesn't like it when you want to add/remove columns in the Export and then try to refresh the profile mapping.It causes an error.

Steps to follow:
1) Create Export Profile that uses RE Export.
2) Modify RE Export to add a column.
3) Go back to Export Profile, and refresh the source using RE Export > Match existing fields by name. And you get this error:
"There was an error showing the source configuration: Object Reference not set to an instance of an object"

No updates happen to the profile, you have to rebuild the profile from scratch. I attempted to Copy the profile and have it use the RE Export, but I get the same error.

When i originally copied the profile from an RE Query to use an RE Export, it allowed me to change the source from Query to Export...but it did NOT map by Field Name with the Source and Connector Field. The column names were the same in the Source, Connector Field in the Query and the Export. I even changed the name in the Export to match what the Connector field name is...and it was not able to match and adjust the mapping.

Can you improve the mapping process for RE Export?
