Before beating your head against the wall, which can hurt you, try to enable 
debug mode in MapServer and have a look to the log. MapServer can give 
interesting information about what he is doing before the "premature end of 
script".

Hope it helps you.

Re: [mapserver-users] [Cluster:FeatureCount] is string?

2013-09-13 Thread Lime, Steve D (MNIT)

Really need Tamas to comment on the clustering specifics but to clarify, 
MapServer stores all attributes as strings. Then they are cast as necessary 
when referenced in an expression.

Subject: [mapserver-users] [Cluster:FeatureCount] is string?

Hi,

I wonder if the [Cluster:FeatureCount] value is a string?
I have a mapfile with three classes like

> EXPRESSION "1"
> EXPRESSION (("[Cluster:FeatureCount]" > "1") and 
> ("[Cluster:FeatureCount]" < "51") EXPRESSION ("[Cluster:FeatureCount]" 
> > "50" )

As result I get mixed symbols, each feature that has a cluster:featurecount 
beginning with 2,3,4,or 5 is symbololized with the styel of the 2nd class (even 
101 or 455) and each feature that has a cluster:featurecount beginning with 
6,7,8,or 9 is symbololized with the styel of the 3. class (even 7 or 9).
An Expression like
> EXPRESSION ("[Cluster:FeatureCount]" > 50 )
(no quotes) does not work.

For a better understanding, here is the resulting image:
http://mapmedia.de/tmp/mapserv.png)

Furthermore it is not posible to calculate with it, sth. like
> SIZE [Cluster:FeatureCount] / 10
does not work.

Thats why I think mapserver treats featurecount as string.
Or am I doing it wrong?

Re: [mapserver-users] Labels stopped working after update

2013-09-13 Thread Lime, Steve D (MNIT)

Depends on how big of a jump in version you made. 6.2 now features multiple 
labels per class. I think you need to do something like:

$label  = $oAirportsClass->getLabel(0);
$label->color->setRGB(0,0,0);
$label->set("font", "verdana");
$label->set("size", MS_LARGE);
$label->set("position", MS_AUTO);
$label->set("antialias", MS_TRUE);

Here are the POST queries output by OpenLayers and the wfs part of the mapfile

Example of the POST request for a non-spatial query which works
