[scxml] update datamodel
Hello,
I've a simple state machine
<?xml version="1.0" encoding="UTF-8"?>
<scxml xmlns="http://www.w3.org/2005/07/scxml" version="1.0"
name="Fan2" initial="Off" exmode="strict">
<datamodel>
<data id="T" expr="10"/>
</datamodel>
<state id="Off">
<onentry>
<log expr="'OnEntry Off'"/>
</onentry>
<transition cond="T > 30" target="On"/>
<onexit>
<log expr="'OnExit Off'"/>
</onexit>
</state>
<state id="On">
<onentry>
<log expr="'OnEntry On'"/>
</onentry>
<transition cond="T < 20" target="Off"/>
<onexit>
<log expr="'OnExit On'"/>
</onexit>
</state>
</scxml>
and like to update T through Java. I tried this:
fan2.getEngine().getRootContext().set("T", "40");
but somehow the engine does not switch into the new state. Do I have
to manually trigger the engine to reevaluate all expression or what
I'am missing?
Thanks in advance for any hint
