Re: Issues with NumberTool?

[csanders]

So what was velocity doing ?

Some problem with pound signs in double quotes ??

Yeah, doesn't look like NumberTool has the problem.  Velocity must be
doing something funky with those # signs. Try defining those strings
with single quotes so that they aren't interpolated.  Really, as a
general rule, if you don't need strings to be interpolated (parsed as
if they were mini-templates), then you should single quote them
instead of double quote.

$NT.format('#,##0.##','190.0')

And for the record, which version of Velocity is this with?

I should also add that I also tried this in my tests:

NumberTool nt = new NumberTool();
Double dbl = new Double("190.00");
System.out.println(nt.format("#,##0.##", dbl));

This does not produce the IOException so it seems to be an artifact of
template rendering.

Hope that helps.

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.
