[maplab-users] Where/How do session vars get saved in gmf_apps?

Paul,

Thank you for your reply. I finally figured most of that out. I think 
the cleaner way will be to just add params to the URL and grab them 
in drawmap.php like you suggested.

BTW, on the scale = 0 problem I had earlier was caused by the fact I 
used $oSession in stead of $oMapSession -- Duho!
