[OpenLayers-Dev] GML Layers is no more visible in vector sandbox revision 2823

Thu Mar 22 07:36:22 EDT 2007

Hi again,

I took a look at the http://openlayers.org/dev/examples/  especially at the 
gml-layer-example.
The GML-layer displays the polygon.xml and may also display the other files
in http://openlayers.org/dev/examples/gml/. I get a response of my WFS which
looks like this:

<wfs:FeatureCollection xsi:schemaLocation="http://www.opengis.net/wfs

So the structure is little bit different. May this perhaps be the cause,
that my GML-layer displays nothing?

Also I 'm still getting the curios error:
>>OpenLayers.MouseListener.MouseDefaults is not a constructor
>> var mouseListener = new OpenLayers.MouseListener.MouseDefaults();
>> in Map.js line 229.

I'm really convinced that I do not use the code which causes the error, so I 
guessed it was an error in OpenLayers. But this also seems not to be the 
case....

Here is my "whole" code (at least the code which contains OpenLayers
things). There really is no use of MouseDefaults in it. I really have no
idea what to do. My form has to be ready next week, so I'm really in a tight
spot. Perhaps I indeirectly use the MouseDefaults??
