setting map.extent puts viewer at highest zoom level

Question

(SFV 1.3, sri 102xxx)

Passing in extents from the database and using the following code to set the map extent. Whenever one of the extents are set, the viewer zooms in all the way.var ext:String = event.data.toString();
    var extArray:Array = ext.split(" ");
    var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]));
    map.extent = extent;

Sometimes the extent works, most of the time it is at the highest zoom level. What calculation is failing and where I can help correct it?

Just had my Homer moment, DOH.

x,y points are backwards

The points were entered as: x2 y2 x1 y1 or vice versa. After reversing the points the extents work great. They were indeed collected using

Thanks again for your assistance!!!

James,

Actually no that I think about this I am pretty far off base with my comment You should not be attempting to set the maps extent using coordinates that are not the same as the maps coordinate system

You absolutely can do this as long as you specify what this new extents WKID is var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]),new SpatialReference(102000));

As an experiment, using the ESRI World_Map 102100 and the Coordinate Banner mod, I zoomed out and collected an extent using the coordinates displayed on the banner. Not sure if this loses precision from the map.toMapFromStage() function. The result was the same, map zoomed in 100%.

The extent:
-7857063.7853 5126174.3537 -7845626.8949 5119715.4248

I searched the entire project for any map.zoomIn() calls or map.extents that may be called out of place but found nothing.
