Hi,
It seems you have to add a random number to the url.
You take as url the same as you take for your gml layer.
yourLayer.setUrl("XML1/FeatureGML.xml?A="+counter++);

Betreff: Re: [OpenLayers-Users] Layer from GML loading only for the first
time
Hi,
Thanks for your reply.
I am afraid I have not understood the solution suggested by you.
You are saying to use the setURL to change the url for a gml layer after
layer creation.
Does that mean the following code:
map.addLayer(new OpenLayers.Layer.GML('choice_features',
"XML1/FeatureGML.xml"))
after the creation of the above layer I use the setURL as below:
choice_features.setUrl("http://....";);
Do i give just the Url for the GML file or do i need to add some random
number to it at the end.
Then how do I load the above Url.
Regards.
