Hi,

this.name should work
(this also works in static contexts and refer to the current class)

Yes, there is.

==================
class Foo {
  static m() {
    println this.name
  }
}

Foo.m()
==================

This works because in static context, groovy maps calls on "this" to calls on the class.

Doesn't work for me (Groovy 1.6.6-SNAPSHOT). The following:

class Foo {
  static main(args) {
    println this.name
  }
}

results in:

java.lang.ClassCastException: java.lang.Class cannot be cast to groovy.lang.GroovyObject

However, "println this.getName()" does work.

Cheers,
Peter

I must have tried it on 1.7.x in that case, because I first tried that code and then replied.

I just noticed that you are invoking this.name from main(), so that bit was different and I had tried it a non-main() method. So issue you have pointed out may be in both 1.6 and 1.7.

It should behave same, though.

I will give it a try later and see what makes main() different.

Sounds like a JIRA to me.

This issue should be found fixed in current 1.6.6 and 1.7-rc-1 snapshots now.
