    Since class inheritance is not available to groovy workflow scripts, I thought I'd try some alternatives, so I gave "interfaces" a go instead. I want to specify an interface that provides the templating for a common behavior I want to achieve. e.g. {{MyFoo.groovy}} could implement an interface specified in {{Foo.groovy}}. Other scripts e.g. {{Bar.groovy}} could then invoke a common interface specified in {{YourFoo.groovy}}, {{MyFoo.groovy}}, {{RonaldsFoo.groovy}} and so on. In trying out a very simple example of an interface to achieve what I want, the groovy-cps compiler errors. Here is the valid groovy code that I tried (and works) under a groovy console: {code} interface Foo { String name() } b = [name: {return "Ronald"}] a = b as Foo println a.name() return {code} This prints {{"Ronald"}} as you'd expect. The code that I tried in an example workflow, I was hoping could do the same, but does not: {code} node { b = [name: {return "Ronald"}] a = b as Foo echo a.name() } interface Foo { String name() } {code} The error that is thrown when I hit "Apply" after entering the code in the Groovy CPS DSL box is: {code} javax.servlet.ServletException: java.lang.NullPointerException: Cannot invoke method
