[OFBiz] Dev - Safe to use cache on views?

[Al Byers]

Ok, here is what I have learned. The reason my entity cache list was not 
keeping entities in the cache seems to be that I was not starting OFBiz 
with enough heap memory set. The arguments that I am using now are:

VMARGS=" - Xms192M -Xmx192 -Dofbiz.admin.port=$ADMIN_PORT 
-Dofbiz.admin.key=$ADMIN_KEY"

(for starting in the debug, it looks like this:
VMARGS=" -Xms192M -Xmx256M -Dofbiz.admin.port=$ADMIN_PORT 
-Dofbiz.admin.key=$ADMIN_KEY -Xrs -Xdebug -Xnoagent -Djava.compiler=NONE 
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8999 "
)

Before I was not setting the -Xms arg at all and David said that what 
was happening was that when the heap needed to expand it would first 
cannibalize the caches first. So the above line in startofbiz.sh seems 
to have fixed that.

Now when I update an entity that is contained in the 
ContentAssocDataResourceViewFrom view, it clears the "entity-list" 
cache, but not the "entity" cache of the same name.
