[mapguide-users] Fusion 2.6 (AIMS 2015) ZoomToSelection Problem

[Jackie Ng]

I think the problem is that the QueryFeatureProperties() API which v2.6
QUERYMAPFEATURES currently uses to assemble the response does not seem to
produce the same expected set of data as QueryFeatures() even though we pass
the same set of parameters to both.

I've been testing on the Sheboygan map where Parcels and Trees are
selectable, and I've been getting cases where selecting a parcel gives me a
selected parcel image, but no attributes because QUERYMAPFEATURES was
fetching the attributes of a selected tree and vice versa.

Rather than try to bash an existing QueryFeatureProperties API into shape
with a metaphorical hammer to make it do something I'm starting to think it
wasn't originally designed for, I've tried to write the feature attributes
into XML response directly from the MgSelection of the MgFeatureInformation
we get. This is proving to be a more reliable approach, and I don't get the
symptoms that I have been getting before.

The patch is here (http://trac.osgeo.org/mapguide/ticket/2459). I've
submitted to -internals for review. It will land in trunk/2.6 by the end of
the week if the patch is okay and/or nobody has made any comments by then.
