Subject Re: Reducing the dojo footprint in Geronimo
Date Thu, 07 Aug 2008 15:03:36 GMT
I may be misunderstanding what your proposing, Donald, but I'm not sure if
this suggestion would actually decrease the dojo footprint at all.  From my
understanding, the monitoring plugin that is included in the EE servers
requires a dojox feature (charting).  This would mean that the monitoring
plugin would pull the dojo-full plugin into the EE server resulting in no
actual decrease in dojo footprint.  This idea would be nifty for custom
server images, but my understanding was that this discussion was in relation
to the EE distributions.  I still like the idea, I'm just not sure it's
going to accomplish what Shrey was suggesting.  I'm inclined to side with
Donald's idea, even though I don't think it will decrease the EE server's
dojo footprint.  It provides users who are building custom assemblies the
option to include dojo easily in their server without worrying about dojox
components they might have no intention of using.
