[Chameleon] Query and LegendTemplate Questions

[Jennifer Zeisloft]

Hello All,

I believe these are largely Chameleon questions, but may also have a
bit to do with MapServer mapfiles.  I've searched both documentation
and past archives of both list-servs but have been unable to figure
this one out on my own.  I really appreciate any help that is offered.
 Thank you in advance!!

Firstly, I would like to identify features in a polygon layer using
the Query widget.  I have been able to accomplish this with a query
template that accesses the .dbf file of the polygon layer, and with a
QUERY type layer in the mapfile.  However, I would like to combine the
polygon and query layers into a single layer in the chameleon legend
so that when a polygon layer is active, it is queryable.  I am sure
this is possible, but my understanding is that a QUERY layer does not
draw anything and a POLYGON layer cannot also be a QUERY layer.

Also, I am wondering how this relates to the Layer Info popup window
that appears when a layer in the legend is clicked.  A category in
this window is "queryable?" and has always shown "no".  The query
layer does not bring up a Layer Info window - I think because the
layer has no "NAME" - and giving this layer a name results in an error
message:

Warning: [MapServer Error]: getString(): Parsing error near
(query):(line 139) in
C:\ms4w\apps\chameleon\htdocs\common\wrapper\map_session.php on line
215

Warning: Failed to open map file

Fatal error: Call to a member function on a non-object in
C:\ms4w\apps\chameleon\htdocs\widgets\KeyMapDHTML\KeyMapDHTML.widget.php
on line 108

Is there a way to resolve this?

Secondly, it seems to me that the html for each query results popup
window is generated automatically as a temp file and that it is
generated as the result of a combination of popup.php, popup.css,
queryresults.phtml, and query.widget.php files.  I would rather not
delve into php at this point - is there a way for a non-programmer to
change the format of the query results popup window?  For example, I
would like to have a vertical rather than horizontal display of the
results, and perhaps be able to modify the title of the popup window.

Thank you again for your help!

Just in case, here is the relevant code from the mapfile:
