Hello Everyone --
Does nVelocity give me a way to dereference variable names, such that
I can build variable names dynamically in my template?
Here is what I'm trying to do. In my controller I send some data to
the view with a dynamic name. For example:
string type = "Widget";
PropertyBag["type"] = type;
PropertyBag[type + "Options"] = GetListOfOptionsByType(type);
Now I have two entries in my PropertyBag. One is called "type" and the
value is "Widget". The other is called "WidgetOptions" and the value
is a list of stuff.
Now, my nVelocity template knows the type ($type == "Widget") and it
knows that the options for that type are going to be stored in a
variable named after the type with "Options" appended to it,
i.e."$WidgetOptions". The problem, though, is that in order to
actually get to the list of options, I must build the second variable
name ($typeOptions) and then dereference it (?????). Do you see what I
mean?
I have tried lots of things:
$$typeOptions
${$type}Options
${{$type}Options}
...just to name a few. I tried using #set and even looked at macros. I
have a feeling nVelocity cannot do what I am asking, but I would be
pleased to be proven wrong.
Thanks!
