[fusion-users] Multiple versions of prototype.js

[Paul Spencer]

Stuart

it is not possible to use two different versions of prototype at the  
same time, nor will it be possible for you to use the new version  
based on MooTools with a version of prototype.  This is an artefact of  
how Prototype and MooTools are built (something I didn't appreciate  
until recently myself).

Your realistic choices are:

1) load your Fusion application into your web page using an iframe or  
frame, thereby separating the two versions of prototype

2) replace the version of prototype used in Fusion (via the Jx  
library) with your version and deal with any issues this creates in  
Fusion/Jx

3) update your code to use the newer version of Prototype that comes  
with Fusion

Only the first option will protect you from upgrading to MapGuide 2.1/ 
Fusion 2.0 (the version that will include MooTools).  Even if you  
modify Fusion to use your version of prototype now, you will  
eventually have to migrate your code to MooTools if you plan on  
upgrading to MGOS 2.1 or a future MGE version.

Sorry for the pain this is likely going to cause you.  Had I realized  
the implications of choosing MooTools, things might have gone  
differently early on.  However, it is too late at this point to go  
back on that decision in the near future.

Cheers

Paul
