Join results are misaligned after no matching record found in secondary data

[ronnielouie]

Join a primary feature source to secondary data, where there is not necessarily a matching secondary record. Inspect the join results via walking the feature reader that is returned from the SelectFeatures() call. Notice that the joined data no longer matches the primary record after a corresponding secondary one cannot be found.

This is best illustrated below:

Primary join key:

AB

BC

MB

NS

NF

ON

QC

YT

Secondary join key:

AB

BC

MB

NS

NL

ON

QC

YT

The result of the join is

Primary_key	Secondary_key
AB	AB
BC	BC
MB	MB
NS	NS
NF	ON
ON	QC
QC	YT
YT	(null)

The correct result should be

Primary_key	Secondary_key
AB	AB
BC	BC
MB	MB
NS	NS
NF	(null)
ON	ON
QC	QC
YT	YT
