I posted this in Flexviewer and got no response. Hopefully get a beter response here....
I developed a web app (flex 3.6) and it seems everything work well in IE and Chrome. However, Firefox displays the error seen in the attachment. I know one way to resolve this is to set the addarcgisbasemaps="false" , however I need the basemaps to be accessible.
Why firefox has a problem with basemaps?
Suggestions?
Thanks.
