Hi Caleb,

When I was looking for places where
hasProgrammingRights is called, I found calls to
c.x.x.api.Context.get() in the templates. I discovered that there is code in the
templates which
implicitly calls $xcontext.get('something') by calling $xcontext.something where
there is no
function Context.getSomething().
Since this is so easy and there is no way to know that
anything is
wrong since Context.get() returns null if you don't have PR, I am proposing that we
do away with the
practice of implicitly referring to functions in $context entirely.
I don't understand what is the problem. Can you be more explicit?
Thanks,
Marius
I used the following command to find implicit context references and I have filled in the
mappings
which I determined manually

find ./

sed -n -e
's/\($xcontext\.[a-zA-Z0-9]*[^a-zA-Z0-9(]\)/\n\1\n/p' | grep '^$xcontext'
| sort

messages and since it
appears to be relatively new code, it convinces me that the $context.blah pattern is
simply
unsafe and should be abandoned at least for the xcontext object.
I would like to fix these now and establish a best practice of avoiding the use of these
in the
future for $xcontext. I myself avoid this pattern entirely but I do not have a compelling
reason to
propose it as a best practice except for $context.
WDYT?
Caleb
