[fusion-users] MapGuide Ent 2010: Fusion and digitize error

[Paul Spencer]

Its approximately the same version of that code as is with the current  
MGOS 2.1 beta.  I think your current work around is probably fine.   
The architecture of this code is changing for the next release and  
will make this problem a non-issue.

You can always replace (after making a backup!) fusion in a mapguide  
release by just moving the current fusion folder and unzipping the new  
fusion in its place.  As fusion does not ship with the mapguide  
templates by default, you will need to copy the contents of templates/ 
mapguide from the original fusion to the newly installed one.  Not  
sure what this does to any support agreements you have with ADSK for  
MGE2010 though :)

Cheers

Paul
