starting on sub-process i realized that i better think out variable declarations as a whole. i know of 4 places where we want to declare variables: * process variables declarations * activity variable declarations (state, task, super-state,...) * task out variable declarations * sub-process out variables <process name="..."> | <variable name="processVariableName" type="..." init="#{expression}"> | <init><string value="fixed string"/></init> | <variable> | | | <activity name="..."> | <variable name="activityScopedVariableName" type="..." init="#{expression}"> | <init><string value="fixed string"/></init> | <variable> | | | <sub-process name='...'> | <in-swimlane name="superProcessSwimlaneName" sub-name="subProcessSwimlaneName" /> | <variable name="subProcessVariableName" init="#{expression}"> | <init><string value="fixed string"/></init> | <variable> | <out-variable name="processVariableName" init="#{expressionResolvedInSubProcessContext}"> | <transition> | <outcome activity="subprocessactivity" /> | <outcome variable="subprocessvariable"><string value="..." /></outcome> | | | <task name="..."> | <variable name="taskVariableName" type="..." init="#{expression}"> | <init><string value="fixed string"/></init> | <variable> | <out-variable name="processVariableName" init="#{expressionResolvedInTaskContext}"> | <transition name="..."> | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4226312#...
