All,

<div class="">I wonder if it wouldn’t be prudent to include data from more than one projection in order to insure that all reprojection conversions are working.

Just as an overall comment, there are 2 very distinct user groups for the demo - people who only care about Web Mercator stuff working, and people who are trying to work in a local projection.<br class="">
<br class="">
</div>
What we have in the demo is working pretty well for the first group, and it is a bit unfriendly to beginners in the second group, as projections show up in multiple places where beginners are likely to run into trouble (e.g. even setting up your zoom levels
in the Mapbook.xml). It's compounded if a user runs into a bug, and doesn't know it's a bug.<br class="">
<br class="">
</div>
Probably worth a review of the docs to see how we might improve in this area...<br class="">

Just by looking at the code in Github I see that there is still no re-projection of the extent before the query call, so i expect that is is still broken (but I will try v2.8). Now that I'm getting results back I ran into the "zoom to results" bug you've
referenced, so that saved me some time. Thanks!<br class="">
<br class="">
Personally, I think the parcel data in our demo should be in EPSG:4326 so we can discover these problems in our testing before release.<br class="">

There was a bug that was fixed recently that may relate:<br class="">

You could try grabbing the relevant changes to query.php:<br class="">

<br class="">
</div>
Or you could try a 2.8 install to see if the same problem is present (before filing a new issue...).<br class="">

Hi Developers (and others),<br class="">
<br class="">
While debugging a user's problem with using his data with query.php, I see that line 376 in github (or line 420-ish in GM 2.7.1):<br class="">
<br class="">
$ext = $queryLayer->getExtent();<br class="">
<br class="">
then the layer's extent is used for the query a little later:<br class="">
<br class="">
$queryLayer->queryByRect($ext);<br class="">
<br class="">
This fails to find any features since in my case the coordinate systems of the map and layer are different, and the queryByrect must be done using a rectangle in the MAP's SRS not the LAYER's SRS. I did a little hack to re-project the extent just before the
queryByRect:<br class="">
<br class="">
// re-project the layer's extent into the map SRS for querying:<br class="">
$map_projection_def = $map->getProjection();<br class="">
$map_projection_obj = ms_newProjectionObj($map_projection_def);<br class="">
<br class="">
if($queryLayer->getProjection() != NULL) {<br class="">
$projection = $queryLayer->getProjection();<br class="">
}<br class="">
if($projection != NULL) {<br class="">
# reproject the query shape as available.<br class="">
$projection = ms_newProjectionObj($projection);<br class="">
}<br class="">
if($projection) {<br class="">
$ext->project($projection, $map_projection_obj);<br class="">
}<br class="">
if($DEBUG) {<br class="">
error_log(implode(',', array($ext->minx,$ext->miny,$ext->maxx,$ext->maxy)));<br class="">
error_log("<br/>extent for query in map SRS.<br/>");<br class="">
}<br class="">
<br class="">
I thought I would get comments before filing an Issue.<br class="">
<br class="">
So any comments?<span class=""><font color="#888888" class=""><br class="">
