[jboss-dev-forums] [Design of JBoss jBPM] - how to define global variables for process in xml

[inxaoc]

Hi!
How to add variables in process-definition.xml to whole process (to make it as global variable which will be visible in any node)? And how to get this variable by using Expressions (like is described here - chapter 18.3. http://docs.jboss.com/jbpm/v3/userguide/jpdl.html#expressions for using in decision node :
#{processInstance.contextInstance.variables['varName']}?? Is it true?
