The exception is corrupting the json formatted response so when
Query.php returns there is a (likely suppressed) javascript error that
prevents Fusion from processing the selection and hence other widgets
from responding to it to load the selection.
Mike, we should be able to reproduce this with some of Jason's data.
Cheers

What response are you getting from Query.php for your maps?

We realized about the Selection widgets, and we went ahead and
included those in the ApplicationDefinition.xml files that we
used. We also noted that the selection does indeed work with the
Sheboygan maps, and as soon as you select parcels, the map
refreshes to indicate your selection, as well as the SelectionInfo
widget shows your selected objects. However, we used the included
Aqua ApplicationDefinition.xml template and only changed
the .MapDefinition files to reflect our maps instead of Sheboygan
and added our custom scripts/urls as widgets to test, and we are
having the selection issues. I even removed everything external to
the initial Aqua template except for one of our maps to load, and
the same thing occurs.
Also of note:
I used the FireBug extension to see the GET and POST commands, and
when running the Sheboygan sample, the selection command issues a
POST of .../fusion/MapGuide/php/Query.php followed by POST .../
fusion/MapGuide/php/Selection.php, whereas our maps only issue
POST of .../fusion/MapGuide/php/Query.php. I don't know if that
has anything to do with the SelectionInfo showing selected objects
for Sheboygan and not for us, or if all of these issues are just
interrelated.

Note that if you are testing with the fusion/samples/mapguide/
standard example, the SelectionPanel and SelectionInfo widgets
aren't enabled in the ApplicationDefinition.xml file as shipped.
You have to uncomment those widgets in the file. We should
probably change that so those widgets are included by default.
In RC4 with the Sheboygan map, the selection should be appearing
highlighted as soon as it is selected.

Oh, looking at your contribution to that thread, it looks like
that problem is Fusion-specific, which is different than ary's
problem (which is PostGIS-specific).
I'm seeing this Fusion selection problem myself on Windows2k3,
IIS installation.

Is that just for PostGIS, or is it happening for other feature
providers too?
Currently Tom has moved that RC4 be tagged as release, so if
this is something that is not specific to the PostGIS provider
and it is critical, you should make sure to create a ticket in
Trac with enough information (data, MGP package, operating
system, web server, which viewer you're using) to replicate the
problem.
If it is PostGIS-specific, then it likely won't be fixed in
MapGuide. Bruno Scott is doing a bunch of work on the PostGIS
provider currently, so hopfully it will be fixed through his
efforts.

I was previously having issues with selection (http://www.nabble.com/Postgis-Selection-Problem-%28additional%29-tt15466067s16610.html
) where it looked like my objects were selected, but nothing
actually was, and RC4 has made great strides to remedy this.
However, my current situation is this:
I can use the selection tool to make selections on the map. But,
they don't show up unless I click the 'Refresh Map' button. And
even then, the statusbar still shows No features selected. But
when I run our script, the output is correct and formatted
accordingly. Yet, If I make a selection programmatically like
stated in the linked post, the selection is highlighted, and the
statusbar reads {0} features selected on {1} layers, yet shows
that two layers are selected in the selection panel, wells and
blocks. And, no matter which block I select--even if the block
has nothing inside--the selection panel always shows the same
two wells selected. Also, if I make a selection with the tool, I
cannot use the 'Clear Selection' tool, but it is available when
objects are selected programmatically.
I don't know what is causing this behavior, but these are my
observations so far. If I come across anything new, I will
update here. At least the selections are working enough to use
and test our scripts, and for that, I am glad.
