FACT(s) (Environment):
OpenEdge 10.1B
SYMPTOM(s):
Invoking WRITE-XML on ProDataSet
DataSet obtained by calling GET-CHANGES on existing DataSet which has had changes made to it
Output from WRITE-XML shows no data
CAUSE:
The original DataSet was defined with multiple NESTED relationships and the changes made to the DataSet were made to tables other than the top-level table. All other tables had NESTED relationships underneath this table so when WRITE-XML was invoked it respected the defined relationships and consequently saw that the top-level table was not changed and ended up writing nothing out.
FIX:
To force WRITE-XML to write out all changes you must turn off the NESTED attribute for the relationships prior to invoking WRITE-XML. This can be accomplished as follows:
SomeChangeDataSet:CREATE-LIKE(SomeOriginalDataSet).
DO iCount = 1 TO SomeChangeDataSet:NUM-RELATIONS:
SomeChangeDataSet:GET-RELATION(iCount):NESTED = FALSE.
END.
SomeChangeDataSet:GET-CHANGES(SomeOriginalDataSet).
/* Now You Can Invoked WRITE-XML And Get What You Expect */
