Newbie Warning...

I have a DTL which accepts HL7 2.3:ORU_R01 And Transforms to Custom Request Target

the target request contains  an array of a custom class named OBXobj with some %string properties which  Extends (%RegisteredObject, %XML.Adaptor)

in the DTL i have a for each loop which should copy OBX segments to the the request.

the DTL test tools works and builds a XML with the OBX info.

when running the Production i get NULL in the Object.

see attached images

1. Test

2. Message sent.

3. Transformation

Whats my problem?

Thanks!
