__showConfigurationPage
    self.showConfigurationPageByName(itm)
  File "/home/20131203-Client/src/NodeConfigurator.py", line 345, in

    page.loadConfig(itm.getIDs()[0],  itm.tmpConfig)
  File "/home/20131203-Client/src/Ui/ConfigurationPages/Page_Circle.py",

        platform = node.get_platform()
self.textLabel_Platform.setText(platform)


/home/20131203-Client/src/node.py

def get_platform(self):
        """ Returns node type

        self.node.addCallback(self.get_model)
        self.node.addCallback(self.success)
        return self.model


    def get_model(self, object):
        model=object.callRemote("getModel")
        return model

    def success(self, model):
        print '1111fff'
        print model
        self.model=model
        return self.model
