Here give me a warning not to exist dialog field. Is there any other option for this?


seems to me you were on the right track, since wanting to display a modal dialog and that is easy to do using the .dialog field of the Scene. So you just have to grab the scene with getScene(). 

i'd do something like this: 

    dlg = createObject("roSGNode", "Dialog")
    port2 = createObject("roMessagePort")
    dlg.observeField("buttonSelected", port2)
    dlg.observeField("wasClosed", port2)

    dlg.buttons = ["OK"]
    
    dlg.getScene().dialog = dlg                  
    while wait(0, port2) = invalid
        ' pass
    end while
    dlg.close = true 'out of propriety
