Hi Michael, hi list,
the problem is, that the url in the featureInfoTunnel request contains no LAYERS parameter, when the layer is invisible because of the maxScale setting. That is why the mapserver throws a ServiceException. Now I have a workaround for my problem. I have changed the "javascript/mod_featureInfoTunnel.php" near line 82. 81 ... 82 mb_ajax_post(path, {'url':currentRequest},function(js_code,status){ 83 var isServiceException = js_code.search(/<ServiceException/) 84 if(js_code && isServiceException == -1){ 85 if(featureInfoLayerPopup == 'true'){ 86 ... Not the nicest code but it works. Now I can use the maxScale setting in conjunction with the featureInfoTunnel module without any error message. Thanks for your support. Greetings Robert Hi Robert, I wonder whether UMN Mapserver in this case throws an error at all ...? Hmm. Looking at your error message, it gets thrown in msLoadWMSGetMapParams. I don't think this function already takes the scale into account, it just collects the layers that are given in the request and checks whether they exist. When drawing the map it just omits them, I guess the same should happen for getFI. I am not totally sure about this and happy to be told the opposite. Could you check your getFeatureInfo Request whether there are any other things happening to the layers or querylayers parameter? Are you using grouped layers?

Hi Robert,
thanks for bringing this up. I haven't made up my mind yet, what the correct solution would be. We'd need to know how the mapservers handle this case. Some facts for a discussion: - the layer parameter is empty because mapbender respects the scale settings, that is correct. - Mapserver throws an exception when the layers parameter is empty (and the mapfile contains no DEFAULT layers) Should Mapbender respect the min/maxscale settings also for querylayers? Still thinking...

Hi Michael,
I don't know what happens, when Mapbender respects the min/maxscale setting also for querylayers. When the QUERY_LAYERS parameter is also empty, the mapserver would throw an exception too. Up to now my skills of the Mapbender code are very limited. So I don't see another solution for now. Greetings Robert Hi Robert, thanks for bringing this up.

Hi Robert,
maybe we should try to find out, how other WMS do this. UMN throws an error when the layers parameter in a request is empty. If others do that as well, Mapbender shouldn't issue such a request (which is already true for getMap, but obviously not for GetFI). I am not aware about what the specs say to this subject. Cheers, Michael 2009/10/2 Robert Walter <[hidden email]>: > Hi Michael, > > I don't know what happens, when Mapbender respects the min/maxscale setting also for querylayers. > When the QUERY_LAYERS parameter is also empty, the mapserver would throw an exception too. > > Up to now my skills of the Mapbender code are very limited.
