Hi again.
I just found a solution to my problem. The Layer.initResolutions has been
rewritten in the nightly build and now it checks if maxResolution and
minResolution is a number. So when I remove the quotation marks from
maxResolution and minResolution in my map options like below the map works fine
again:
var mapOptions =
{
projection: 'EPSG:25832',
units: 'm',
maxExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),
minResolution: 0.125,
maxResolution: 768,
restrictedExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),
controls:
[
]
};
maxResolution and minResolution can be set to 'auto' so I assumed it could only
be a string. My mistake...

OpenLayers
Hi everybody.
In OpenLayers 2.9.1 my map options is defined with a maxResolution,
minResolution and a MaxExtent like below:
var mapOptions =
{
projection: 'EPSG:25832',
units: 'm',
maxExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),
minResolution: '0.125',
maxResolution: '768',
restrictedExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),
controls:
[
]
};
This works fine in OpenLayers 2.9.1 but doesn't work with the nightly build
(version 19-07-2010 and 14-06-2010)
In the nightly build I get this error in firebug when adding the first layer to
the map:
this.resolutions is undefined: zoom = Math.max(0, Math.min(zoom,
this.resolutions.length - 1)); (Layer.js (line 1061))
When I define the resolutions in my map options like below the map works fine
again:
var mapOptions =
{
projection: 'EPSG:25832',
units: 'm',
maxExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),
minResolution: '0.125',
maxResolution: '768',
restrictedExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),
resolutions: [768, 384, 192, 96, 48, 24, 12, 6, 3, 1.5, 0.75, 0.375, 0.185],
controls:
[
]
};
I can see that there are some issues with the resolutions:
http://trac.openlayers.org/ticket/2427
My question is now do I always need to add the resolutions in map options or
can I use maxResolution, minResolution and a MaxExtent?
Regards Esben
