I created a new widget that you might find useful.
Tucked away in the map context menu are three XY operations
1. Copy XY
2. Project XY (configurable)
3. Go To XY
Hope you find it useful!

Great widget. However I've found a problem using Goto XY Custom, I hope you can clarify me. In my place I've the following lines in xml file:
<coordinateSystem name="ETRS89 UTM Zona 30" wkid="25830" decimals="2"/>
<coordinateSystem name="ED50 UTM Zona 30" wkid="23030" decimals="2"/>
But I've noticed that coordinates in wkid=25830 works fine (that is, the location is accurate), however coordinates in wkid=23030 are moved about 170 meters, so that isn't suitable. Any idea?
I've created a sample for you can test it, in http://iderm.imida.es/drew
The following coordinate (x=664157, y=4206606) in coordinate system name="ETRS89 UTM Zona 30" wkid="25830", is the center of a traffic circle that you can see. And the following coordinate (x=664269, y=4206813) in coordinate system name="ED50 UTM Zona 30" wkid="23030" is the same location, however your widget displays it moved.
I'm facing a weird bug with your widget. It work fine until yesterday, when suddenly the option "Go to XY coordinates" shows always this message "Error projecting coordinates". The other tools included like copy to clipboard an project coordinates work well, the trouble in only with the Go to option. I use my own geometry service, then i switch for the ESRI geometry service but nothing happens. In addition the viewshed widget don't work since yesterday either.
Could be an Flex upgrade that cause the bug?, my other widgets work fine and like said before the only tool broken is Go To XY.
Thanks in advance for any help
PD. Sorry for my bad english.
I'm totally sure about the coordinates I've provided you. Because the original orto (aerial image) is in ED50 and I've got the coordinates with ArcMap. Besides, even the location in ETRS89 that your widget provides is not totally accurate because the coordinates are the center of the traffic circle and your widget in ETRS89 displays the icon a little displaced (about 3 meters).
