[Gwt-openlayers-users] Changing map projection on the fly

[Jon B. <jon...@go...>]

Hi,

I've got a map with a single WMS layer in EPSG:4326, but the WMS also
supports other projections (say, EPSG:9009130).  Is there an way that I can
change the project of the map and the WMS layer on the fly?  I'm trying to
do something like (bear in mind I'm using gwt-openlayers):

MapOptions newOptions = new MapOptions();
newOptions.setProjection(srs);
LayerOptions newLayerOptions = new LayerOptions();
newLayerOptions.setProjection(srs);
mapWidget.getMap().setOptions(newOptions);
for (int i = 0; i < mapWidget.getMap().getLayers().length; i++) {
mapWidget.getMap().getLayers()[i].addOptions(newLayerOptions);
}

but this does nothing (no errors, just nothing happens).

Is there a way of just completely destroying the map and reloading it's
contents? I assume this would be quite simple but I've had no luck so far.

Thanks,

Jon
