[Tilecache] Problems with Tilecache and WMS

[joel bandibas]

Hello Martin,

How about replacing the  "maxExtent" statement in your tilecache.cfg file to 
"bbox".

Hi Linde,

concerning my first problem (I have a new problem described at end of mail 
:( ) thanks for the answer but now I've defined my layer in the 
tilecache.cfg like this:

[mapserverwms_agg]
type=WMS
url= http://localhost/cgi-bin/mapserv?map=data/wms2.map
layers=bezirk_grenzen01,staat01,fluss01,bezirk_grenzen01,stadt01,layer_mapany_080305_3ba6226287c1622
maxResolution = 420
srs=EPSG:31297
maxExtent = 
384619.116883103,467965.222077892,505102.701298797,534231.193506524
----------------------------------------------------------------------

The mapfile has the same maxextend and the projection code of wms and all 
layers is 31297 --> the maxResolution is the same as in the Openlayers html 
file:

---------------------------------------------------------------
var mapOptions = {maxExtent: new 
OpenLayers.Bounds(384619.116883103,467965.222077892,505102.701298797,534231.193506524),
maxResolution:420,numZoomLevels:21,
projection:"EPSG:31297"
};

        function init(){
            map = new OpenLayers.Map($('map'),mapOptions);
            layer = new OpenLayers.Layer.WMS( 
"tiledcache","http://localhost/cgi-bin/tilecache-2.10/tilecache.cgi?", 
{layers: 'mapserverwms_agg',format:'image/png'} );
----------------------------------------------------------------
Here's the beginning of my mapfile (wms2.map) + a layer definition:

    END
  END
--------------------------------------------------------------------

When I try to load this in Openlayers I only get pink tiles with a red point 
in it.

My Second problem:

I tried an other example from someone else having problems with Tilecache:
The problem is that the map isn't drawn when using the "scales" attribute
- here are the mapoptions he's using:

var mapOptions = { projection: mapProjection,

scales: [17500000, 14000000, 7000000, 3000000, 2000000, 1000000, 400000, 
250000],

//maxResolution: "auto",
 --> commented out, but when he's using this  code its working
//maxExtent: mapRestriction,
restrictedExtent: mapRestriction,

controls: []

  };
In the tilecahce config he has just given the layers, layername and url.

Would be very nice if someone could help us!

Thanks in advance!

martin
