"$value" when null
Hi ,
I wonder why it is so,
in my template the $!profile.FromAddr renders to $value, and all
other fields of the object hidden under "profile" that are null, I
thought that the $! will be quiet, that is return a "" in case of a
null, but it is very loud and returns the bloody $value all the time
explanations?

Thanks,

baffling. Can you send some code demonstrating the problem? To
private email would be fine.

why would $value come out?
GMJ> if the reference is something other than '$value', then the reference

it's $value regardless of the parameter that's calling it
$!profile.getFromAddr()
$!profile.getName()
it happens when the returning value is null, if it's any string
including "" the string value is then printed

Why would '$value' come out?
if the reference is something other than '$value', then the reference
should print, not the string 'value'

profile is a object (persisted by turque) and getFromAddr() is one of
it's getter methods which returns a null String in some cases (a new
object)
GMJ> And you see '$value' in the output?
yes

I don't quite understand. I assume that you have something under
'profile' in the context? it has a method getFromAddr() or get(String)
that returns null.
And you see '$value' in the output?
