Hello list,
within a GeoExt project I used the ScaleStore due to the example at
http://api.geoext.org/1.0/examples/zoom-chooser.html.
The problem is that some scales are not shown correctly in the scale
chooser, for example 1:49999 instead of 1:50000. Some recherche
clarified that in the populateFromMap() function in
GeoExt.data.ScaleStore the scales are always calculated with
OpenLayers.Util.getScaleFromResolution(...), although they are defined
in this.map.scales.
To fix this problem for my project I modified the ScaleStore.js (see
attached patch). Maybe this modification could be interesting for the
general GeoExt code base.
Thanks for any review.
Best regards,
Chris
