ArcGISImageServiceLayer

hi all,

bit of a mystery here.  i've got an ImageService layer in my map.  it displays and works fine as long as it never leaves the maps current view extent.

for example, the image service layer covers the approximate extents of houston.  if the user pans out of the houston area proper, say to The Woodlands (just north of houston), the imagery is no longer in view because the imagery doesn't cover that far north.  that's to be expected.  however, panning back south to houston does not refresh the imagery. 

when initially panning out of the imagery's coverage (up to The Woodlands in my example above), fiddler shows  "error":{"code":500,"message":"Failed to get image data.","details":[]}}

moreover, there are no further calls by the Map to the image server after receiving the error above, even if i pan/zoom back to the original extent at which the imagery displayed properly before.  zoom in/zoom out....nada.  it simply displays the last retrieved image from the image server, never refreshing the extent or zoom.  it's like the layer's connection to the image server's URL is broken after the error and the last image retrieved is the last image you get.  we will need to be able to pan outside the extent of the image service, so setting a restraining extent is not an option.

any help would be appreciated.

This was a known issue in v1.1 but has since been resolved. Are you using v1.2 or v2.0beta ?
