Short reply since I'm running out of email time.

You have a handle to the SCInstance (use the expression evaluator
rather than context lookup where appropriate):

  http://commons.apache.org/scxml/0.8/apidocs/org/apache/commons/scxml/SCInstance.html

See this page (particularly, the latter half):

  http://commons.apache.org/scxml/guide/datamodel.html


> For example, for the following simple SCML document:

<snip/>

All expressions untested, but meant to give you some hints:

<cs:var name="retrievedvalue" expr="Data(label, 'value')"/>


> - How can I change this value from the custom action ?
<snap/>

<assign location="Data(label, 'value')" expr="'NAME2'"/>

See this post:

  http://markmail.org/message/a3dtad2sfipehois

The rest of that thread may be useful to glance at as well.
