[Laszlo-dev] dependence on ExternalInterface in swf9

[Henry Minsky]

I added a conditional on the "available" flag, which seems to work OK
   if (this.isroot && DojoExternalInterface.available) {
            // Expose your methods
            DojoExternalInterface.addCallback("getCanvasAttribute",
lz.History, lz.History.getCanvasAttribute);
            DojoExternalInterface.addCallback("setCanvasAttribute",
lz.History, lz.History.setCanvasAttribute);
            DojoExternalInterface.addCallback("callMethod", lz.History,
lz.History.callMethod);
            DojoExternalInterface.addCallback("receiveHistory", lz.History,
lz.History.receiveHistory);

            // Tell JavaScript that you are ready to have method calls
            DojoExternalInterface.loaded();
          }

the layouts are working fine now, it must have been the error getting thrown
before that messed up
app initialization
