Dynamic DataSets (Oh joy weird bug)

[ForEachInvoiceDelete]

One of our developers has been messing about for me testing some dynamic dataset stuff and came across something weird.

If you use an input/output dataset handle, when it comes back out on the output, its stripped all the data relations!

I have had a look and i am also stumped! Anyone else came across this or can point me at something silly in the code?

Running an internal procedure to do data relations using an input/output dataset handle. (I sincerely apologize for the craptastic nature of this code, its play around stuff and would never be in production in this state)

/* running this internal procedure */
RUN AddRelationnested(INPUT 2, 
                INPUT 3,
                INPUT keyfields,
                INPUT-OUTPUT DATASET-HANDLE hResultSet).   

hResultSet:write-xml("file", "/home/iSAMS/Dev/CodeJason/TestXML.XML").  /* XML is not nested, cus progress decided that using input-output can strip out data-relations... */

PROCEDURE AddRelationnested:
    
    DEFINE INPUT PARAMETER ipParentbuff AS INT    NO-UNDO.
    DEFINE INPUT PARAMETER ipChildbuff  AS INT    NO-UNDO.
    DEFINE INPUT PARAMETER ipKeyFields  AS CHARACTER NO-UNDO.
    DEFINE INPUT-OUTPUT PARAMETER DATASET-HANDLE ophResultSet.

    DEFINE VARIABLE PARENT1 AS HANDLE.
    DEFINE VARIABLE child AS HANDLE.
    DEFINE VARIABLE intcnt AS INTEGER.
    DEFINE VARIABLE hBuffer        AS HANDLE NO-UNDO EXTENT 40.
        
            DO intcnt = 1 TO ophResultSet:NUM-BUFFERS:
       hBuffer[intcnt] = ophResultSet:GET-BUFFER-HANDLE(intcnt).
        MESSAGE "NAMES" intcnt hBuffer[intcnt]:NAME.  
        
        IF hBuffer[intcnt]:NAME = "someparenttable" THEN ASSIGN parent1 = hBuffer[intcnt].
         IF hBuffer[intcnt]:NAME = "somechildtable" THEN ASSIGN child = hBuffer[intcnt].
         
         END.
        
        MESSAGE "JASE" "," ipkeyfields "," parent1:name "," child:name VIEW-AS ALERT-BOX.

        
        ophResultSet:ADD-RELATION(parent1,
                                  child,
                                  ipkeyfields,FALSE,TRUE,TRUE,FALSE,FALSE). 
                                      
  //  END.
  

     //ophResultSet:NESTED = TRUE.   
     
     ophResultSet:write-xml("file", "/home/iSAMS/Dev/CodeJason/TestXMLCRinclude.XML"). /* Here the XML is nested nicely as i hoped */

END PROCEDURE.

What happens if you use a "BIND" or "BY-VALUE" option on the INPUT-OUTPUT Parameter?
DEFINE INPUT-OUTPUT PARAMETER DATASET-HANDLE ophResultSet.
