[Chameleon] ExtentHistory widget questions

[Paul Spencer]

Jennifer,

It is quite likely that the ExtentHistory widget does not work with  
JSAPI.

I believe the ExtentHistory widget looks at the current map extents  
during the DrawPublish phase to see if the map has changed extents  
from its previous last state.  You need to make sure that you are  
changing the map extents in the ParseURL phase rather than later in  
the DrawPublish phase OR change the priority of your widget to be  
higher that the ExtentHistory widget so that it is processed first  
(this may not work)

Cheers

Paul
