I have a custom transformer. One of the incoming attribute values contains a comma separated list of strings. As soon as the record passes through any subsequent transformer, the value is set to null.
Here is the incoming data with WOTEMPALTEIDs as the value that's getting dropped.
After passing through any transformer (AttributeManager in this example), WOTEMPLATEIDs values are dropped to null. The other values are unchanged.
Thanks
