[Mapserver-users] itemnquery and [shpext]

[Steve Lime]

I'm wondering if the code to convert a shape from the ESRI API format to

the MapServer format isn't updating the shape extent. Can you get to 
the shape properties via the other query mechanisms or are they all
busted? 
(The error message makes sense based on the extent values.) I'll check
the SDE source now...

Dear List,
Maybe this is simple, cause I'm missing something. Maybe not. What I'm

trying to do is to make a simple itemnquery (item/value) get the
results 
and zoom the map to the extent of the result shapes. So what I thought
I 
do is simply place [shpext] in my template file to get the extent and 
use this for creating the new map. Work fine except for the fact that 
the only thing I get back for [shpext] is '-1 -1 -1 -1'. Same for 
[shpmid] or any other extent related informationen about the shape. If
I 
place mapext=[shapes] in my request (just to give it a shoot) mapserver

tells me that it's not possible to generate a valid mapextent from 
selected shapes.

Here is the setting

-qlayer is of polygon type.
-Datasource is SDE (8.2)
-Mapserver is 3.6.1

and here is my request:

http://mymachine/cgi-bin/mapserv? 
map=/var/apache/htdocs/project/myMap.map
&mode=itemnquery
&qLayer=myLayer
&map_myLayer_filter="ITEM='VALUE'"
&map_myLayer_data=SDEUSER.SDETABALE,SHAPE
&map_myLayer_header=templates/searchheader.html
&map_myLayer_template=templates/search.html
&map_myLayer_footer=templates/searchcellfooter.html

Any hint is appreciated.
regards
Oliver
