I'm seeing changed behaviour in the sample-store project after
startup. If I fire up the launcher and point Firefox with Firebird at
http://localhost:8080/store/, the first time I run it I see Firebird
"Break on Error"
tuscany is not defined
Line 29
which is ...
var catalog = new tuscany.sca.Reference("catalog");
and the console contains ....
store.composite ready for big business !!!

If I allow the execution to proceed, Firebird tells me catalog is not defined
allowing the execution to proceed further gives a popup "catalog is
not defined"
If I continue refreshing the browser, this behaviour repeats for a
further 2 occasions, If I then refresh one more time I see the
store's catalog perfectly well and can add items to the cart.
does anyone have any clues as to what's changed or why this is happening?
