Thank you Raul, using _eventdatamap did help. I'd like to summarize the
proposed solutions
(with JEXL as expression language), please correct them when necessary:
1) access the simple string content of thze event payload ?
<transition event="view" cond="_eventdatamap['view'].text != null">
2) access XML event payload via XPath ?
<transition event="event.bar"
cond="Data(_eventdatamap['event.bar'].rootdata,'root/one') == 1"/>
3) send a subtree of an XML data model along with an event ?
- first define a local variable holding the required data excerpt via the custom
action "cs:var"
where xmlns:cs="http://commons.apache.org/scxml";, since <datamodel> is
valid only in context
of <state>, not within an executable content:
<cs:var name="text" expr="Data(xmltext,'text')"/>
- reference the variable via @namelist like an ordinary datamodel part:
<send event="'view'" namelist="text" />
Best regards ... and a happy New Year ;o)
