1) What do we do about determining if a reference is null in VTL?

- use something like : #if( $foo == null )
+0, but make it uppercase NULL to reflect the constantness of it.

- or #ifdefined( $foo ) or #ifdef( $foo )
This is trivially easy to do.

Hi,
1rst: reconsider your design; your example causes a infinite depth
call tree and will end up in an OutOfMemoryException... Velocity
has some guards in recursive parses (property: directive.parse.maxdepth = 10),
but it does not look like it guards against deep macro calls.

##

Hi,
I remember having problems with the introspector when accessing
static methods of a class itself. But somehow I cannot believe
that it is causing problems when the class was instantiated.
If you tested removing the static from the getter, and it still
does not work:
public String
You can also use plain VTL:
#set( $id = $number )
#set( $len = $id.length() - 4 )
$id.substring($len)
To simplify the use, you can create a macro for this:
#macro( fourdigits $number )#*
*##* #local( $id $len ) *##*-- optional directive, avoids polluting
context
*##set( $id =

Hi,
have you tried the Integer class methods:
## create an integer instance to be used as a tool
#set( $Integer = 0 )
##...
## retrieve your number string
#set( $countString = $!data.getRequest().getParameter(countRow) )
## convert it to an Integer
#set( $count = $Integer.parseInt($countString) )
.
OTOH, some folks would consider it breaking MVC philosofy to use
such code in templates.

The isA method works, but (at the moment) only checks the actual
classname (not superclasses). Before I go about working this out, I just

The reson for not allowing a null in the context was the original
implementation with a Hashtable backed context, which did not allow
nulls. The original designers thought that other implementations
should also be shielded from dealing with null values, eg. databases
(also CORBA) often can't.
Now
to simply create your input file
with ISO-8859-7, use Velocity.getTemplate(template file name, ISO-8859-7)
and then write the output in UTF-8 and have the proper first line
