Constrained Map Extent in Flex

Question

Hi,
Does anyone know how to apply constrained Map Extent in Flex Viewer 2.1. I found one implemented on Sample Flex Viewer 1.3. http://forums.esri.com/Thread.asp?c=158&f=2421&t=295234&mc=0. But not sure how to apply in 2.1, getting so many errors.
Thanks.

Hey Mattias,
I did those changes too... and I am having the same problem as you do... nothing shows up.

@Matt Williams: Thanks for your response.

I would like this in my Flex Viewer 2.1 too, I actually tried rewriting Roberts implemetation for the SFV 1.3 to the Flex Viewer 2.1. I managed to get rid of all errors, but when I ran the application there wasn't a map at all, all was blank, that's were I gave up.
It will need a lot more modifications than changing extent.containsExtent to extent.contains, to apply this to the FlexViewer 2.1 that's for sure 🙂

Not sure if this will help you or not. This is the sample code on Mansour's blog, before it was modified for the FSV 1.3. http://thunderheadxpler.blogspot.com/2009/01/constraining-map-extent.html The only change I had to make to the SampleMap.as file was on line 65... WAS: if( extent.containsExtent( m_initialExtent )) NOW: if( extent.contains( m_initialExtent )) Then the mxml looks something like this: Like I said, not sure if this will help you or not... Good Luck!
