[OpenLayers-Users] map.RemoveLayer() does not work

[Leich Tobias]

the GML-file is on the webserver, right?

do you see that it reloads this file from the webserver?

otherwise it could be a caching issue of openlayers or your webserver...

Hi Leich,

Thanks for your reply.
It worked.

However I am having one problem.
I am removing one layer 'choice_features' using your code and then adding
one by the same name using
the following code:

 map.addLayer(new OpenLayers.Layer.GML("choice_features",
"XML1/FeatureGML.xml")); 

This layer is being added from the file FeatureGML.xml in the folder XML1.
The GML file is created at run time and with every change in selection its
contents also changes.
But the selected feature on the map remains the same after the first
selection.
Only the first time does it show the feature correctly.After that it shows
the first one irrespective of the feature that is selected.

What wrong am I doing & how to set it right?

Thanks again.
