Changing XmlListModel query value in a State

From pplp in the Declarative UI forum:

Hi,

I am trying to change the query of a XmlListModel when I switch to a specific state. However it seems that the StateChangeScript is only called during initialization (the debug print I put in there is not called when I switch state)

State {
name: "stateFoo";
when: mouseRegion.pressed == true;
PropertyChanges {
target: myXmlModel;
query: "/foo/bar";
}
StateChangeScript {
script: {
myXmlModel.reload();
print('Reload stateFoo);
}
}
}

Am I missing anything ? Does dynamicaly changing the query of a XmlListModel is supported ?

Thanks in advance
