Subject [jira] Created: (SCXML-26) Add parameter to Evaluator.newContext
Date Mon, 02 Oct 2006 12:56:19 GMT
Add parameter to Evaluator.newContext
-------------------------------------

                 Key: SCXML-26
                 URL: http://issues.apache.org/jira/browse/SCXML-26
             Project: Commons SCXML
          Issue Type: Improvement
    Affects Versions: 0.5
            Reporter: Hallvard Trætteberg


The Evaluator.newContext method currently takes one argument, the parent context. However,
to make it easier for the context to link to relevant application data, it would be nice if
it also took a TransitionTarget argument, i.e. have the signature     public Context newContext(TransitionTarget
target, Context parent); By including the target in the context, it becomes easier for expressions
to refer to contextual data. In my case, SCXML is used together with data bindings, and expressions
are used to refer to data in the context of states and transitions. I had to modify SCXML
as suggested above, to provide the link between state and data bindings.
