Hello,

In bookmark widget, I am changing my own value depending upon my map but when I click that bookmark its not showing my desired extent/place.

From extent helper I have got the following extent:

<map initialextent="10064190 2728180 10065620 2728629" top="40">

<bookmark name="This Area">10064190 2728180 10065620 2728630</bookmark>

There is two problems.

1. If I use the initialextent in the main config.xml its not showing the map.
2. if the intialextent remain blank and I use the bookmark extent then the map is showing but when I click the bookmark in widget again the map is not showing.

In ArcMap it showing accurate lon/lat in degree and meter. In meter the Min X,Y and Max X,Y is 235948.444, 26334777.105, 237069.221, 2634359.756 respectively. I am using the following projection System:

Projection: Transverse_Mercator
False_Easting: 500000.000000
False_Northing: 0.000000
Central_Meridian: 93.000000
Scale_Factor: 0.999600
Latitude_Of_Origin: 0.000000
Linear Unit: Meter (1.000000)

Geographic Coordinate System: GCS_WGS_1984
Angular Unit: Degree (0.017453292519943299)
Prime Meridian: Greenwich (0.000000000000000000)
Datum: D_WGS_1984
  Spheroid: WGS_1984
    Semimajor Axis: 6378137.000000000000000000
    Semiminor Axis: 6356752.314245179300000000
    Inverse Flattening: 298.257223563000030000


[N.B. I am using a small area (Dhaka, Bangladesh) dynamic map and a local (hard disk) tiled cached map]

What projection is your map in?  What's the projection of your <basemap> layers?

I am using a base map that is created by tiles cached map service and it was based on data having the projection system "Transverse-Mercator"

That extent is quite zoomed in, maybe there are no tiles at that zoom level?  What happens if you zoom out a few levels once it is "not showing map"?
