Comment:

 In Openlayers.js

 Line 10856:
 if (window.Proj4js) {
       this.proj = new Proj4js.Proj(projCode);
 }
 If proj4js included, the projection will be initialized.

 Line 20817:
 this.units = this.projection.getUnits() || this.units || this.map.units;
 If the projection has units, the layer’s unit will be the projection’s
 unit rather than map’s unit.
 However, for openlayers maps, the default coordinate system is always
 EPSG:4326, so the units will always be degrees.

 In Map.js

 Line 918:
 getUnits: function() {
       return this.oMapOL.baseLayer.units;
 },

 The map’s units is its baselayer’s units, so the OptionView widget will
 get the degrees as unit and the initial view of non-degrees map will not
 be shown correctly.
