Hi Jochen,
Let's have a look at some normal examples:
`println "Hello, ${name}"` // length of "Jochen" is 6, length of "Daniel" is
6 too
`println "Path: ${path}"` // the length of some file location is usually
more than 8, e.g. D:\workspace\groovy
```
<html>
<body>
${includedBody} // the length of html body is usually more than 8 too
</body>
</html>
```
So I think the original possible size(i.e. 1) of value is too small
;-)
Cheers,
Daniel.Sun
