silent references cause strict reference checking to fail
Hi!
With some enthusiasm from my dev team, I just turned strict error
checking on for the first time. Not surprisingly, our app
immediately had some errors.
I was surprised to find that it was failing even with silent
references. Does anyone remember if that's intentional?
<input class="signupInput" type="text" id="StxtFirstNames"
name="firstName" value="$!user.firstName"/>
org.apache.velocity.exception.MethodInvocationException: Variable
$user has not been set at layout/slide_login.vm[line 13, column 117]
To me that reduces the usefulness of this feature-- we use silent
references a lot, and it doesn't make sense to me that they would all
cause errors. I was hoping to do a better job of find errors like
"$user.firstname" where $user wasn't set. But with $!user.firstName I
now have to go through the site and put an #if in every location I
want to be blank if its undefined.
Can anyone using this feature comment?
Thanks,
WILL

I don't use the feature, but my understanding is that strict reference
mode expects all references used to exist in the context. The quiet
notation--in strict reference mode--is for null values, not invalid
references.

Only if you set the property "runtime.references.strict" to true.

We used $!user.firstName type of notation a lot, it has been very
helpful. Hope this is not broken in the new releases...
