-------------------------------
Summary: Javascript engine requires global context execution
Key: SCXML-246
URL: https://issues.apache.org/jira/browse/SCXML-246
Project: Commons SCXML
Issue Type: Improvement
Reporter: Ate Douma
Assignee: Ate Douma
Fix For: 2.0
The javascript engine uses a global Javscript context (e.g. the "global" state)
which retains its state across SCXML script evaluation execution.
The (currently default) custom feature of Commons SCXML to nest SCXML state
contexts therefore cannot reliably be used for the Javascript language.
Note that the SCXML specification explicitely states that all datamodel state
should be shared globally as well.
To retain the custom Commons SCXML feature, a new Evaluator characteristic is
introduced which will specify if a specific (language) Evaluator requires a
global context or not, which for the Javascript Evaluator (JSEvaluator) will be
set to true.
