Re: [WebMacro-user] How to get the context into a ContextTool

[marcel.huijkman <mar...@ra...>]

I'm playing with this 'trick' but can't get it to work.

in my webmacro.defaults I've got this:
ContextTools.Info: org.webmacro.util.Info

But when I do this in my template:
$Info

It says:
Exception:org.webmacro.PropertyException$UndefinedVariableException:
Attempted to write an undefined variable: $Info at 
c:\mydir\wsf\templates\index.wmt:15.1

So I think I must be doing something wrong.

If somebody could kick me in the right direction, I'll sent some virtual 
flowers from Holland :-)
