Lo=C3=AFc Qu=C3=A9ran commented on SCXML-108:
-----------------------------------

More details on my previous comment:

In oacs.io.SCXMLSerializer.serializeActions(final StringBuffer b, final Lis=
t<Action> l, final String indent), oacs.model.Scripts are not taken into ac=
count even in J6 branch.

Am I misunderstanding something ?

What is more, http://www.w3.org/TR/scxml/#script-module states (sic) that t=
o support the script module, one must "Redefine the <scxml> element to allo=
w <script> as a child." This is not possible, as <onentry> is not possible =
child of <scxml> (which it should even without the script module). Please, =
see no criticism here.


The following does not execute properly:
<?xml version=3D"1.0"?>
<scxml xmlns=3D"http://www.w3.org/2005/07/scxml"
       version=3D"1.0"
       initial=3D"script">
      =20
       <!-- Should work, but neither script not onentry is supported here. =
SCXMLReader does not read them. -->
    <script>
=09function Hello(s) {
=09    // Private variable
=09     var what =3D String(s);
=09
            // Public method
            this.say =3D function() {
                return "Hello " + what + "!\n";
=09    };
=09}
    </script>

    <datamodel>
        <data id=3D"s" expr=3D"'Bonjour tout le monde !\n'"/>
    </datamodel>

    <state id=3D"script">
        <onentry>
            <script>
            =09hello_world =3D new Hello("world");
=09=09s =3D hello_world.say();
            </script>
        </onentry>
        <transition target=3D"end" cond=3D"s =3D=3D'Hello world!\n'"/>
    </state>

    <final id=3D"end"/>

</scxml>

 The only workaround I've found is to add a state with onentry script that =
defines "script" state as a sub state.
