Hello... just this morning I needed to do some "in-template" number
formatting and pulled the VelocityTools NumberTool off the shelf. Now
that I'm trying to use it, I'm having some issues.
First, I've got a number tool in the context - context.put("NT", new
NumberTool())
Next, I try to format a number in the template - #set($SW =
$NT.format("#,##0.##", "190.00"))
The "190.00" is actually pulled from the context, but there are other
tests ahead of this to make sure we've got a real value there. When
the template is rendered, I get this error message:
java.io.IOException:
org.apache.velocity.exception.MethodInvocationException: Invocation of
method 'format' in class org.apache.velocity.tools.generic.NumberTool
threw exception java.lang.IllegalArgumentException: Malformed pattern
"#," @ template.vm[57,32]
at ...
Now what is odd about this, is that it IS a valid number format - and
looking at the source of the NumberTool, it looks like it would just
stuff those values into a DecimalFormat and be done with it. Is
velocity choking because of the #-pound-signs?
I double checked my format with these lines:
DecimalFormat f = new DecimalFormat("#,##0.##");
System.out.println(f.format(190.00D));
And this produces the result I expect: "190"
Also, I do have the Locale in the context too - it's just the default
Locale which it looks like would be picked up automatically when not
specified so I've not tried this avenue.
Any thoughts on this?
Many thanks in advance.
