groovy scripting

Hi All, I'm starting to have a look at groovy scripting in xwiki and have a couple of basic questions: In the example below (from xwiki.org) <% def foo(list, value) { println "Calling function foo() with param ${value} <br>"; list << value; } x = []; foo(x, 1); foo(x, 2); foo(x, 3); foo(x, 4); println "Creating list ${x}"; %> 1) does the groovy variable ${value} get translated before the velocity ${value} (if defined) or vice versa? 2) I tried the example and get the following result: Calling function foo() with param 1 Calling function foo() with param 2 Calling function foo() with param 3 Calling function foo() with param 4 Creating list 1, 2, 3, 4? where the "1, 2, 3, 4?" is a link to "1,+2,+3,+4". I assume the output from groovy is then processed by the xwiki syntax? Thanks Duke
