Version

Tell us which versions you are using:

react-native-router-flux v3.31.2
react-native v15.2.1

Expected behaviour

I don't know what i'm doing wrong but when i try to call Actions.dialog() multiple times, i got this error.

I thought this fix #327 fixed it but it should be something else then.

The only time i dont have this, is when i use pop() to close it. Unfortunalty, i dont want to pop (it may break other functionalities in my app).

Actual behaviour

1:$dialog_1_dialog. Child keys must be unique; when two children share a key, only the first child will be used.

I am facing the exact same warning. Are there solutions available?

I finaly found out a hack few minutes ago.

// Dialog

class Dialog extends React.Component {
    constructor() {
        super();

        this.state = {
            visible: false
        };

        this.onCloseDialog = this.onCloseDialog.bind(this);
    }

    componentWillReceiveProps(nextProps) {
        if (nextProps.visible) {
            this.setState({visible: nextProps.visible});
        }
    }

    onCloseDialog() {
        this.setState({visible: false});
    }

    render() {
        return (this.state.visible) ? (
            <View>
                ...
                <TouchableOpacity onPress={this.onCloseDialog}>
                    <Image source={ require("../Ressources/Images/interface-croix.png") }/>
                </TouchableOpacity>
            </View>
        ) : null;
    }
}

export default connect(null, {})(Dialog);

// index.ios.js

...
<Router name="root" hideNavBar={true}>
    <Scene key="modal" component={Modal} >
        <Scene key="root">
            <Scene key="launch" initial={true} component={Launch} />
            ...
        </Scene>

        {/*Modales*/}
        <Scene key="dialog" component={Dialog} direction="vertical"/>
        ...

// Launch

...
// Default visible state of dialog is false, it will not show up this time
Actions.dialog();

// Other components where i need to show the dialog

...
// We get the new visible value from componentWillReceiveProps, the dialog will show up this time
Actions.refresh(key: "dialog", visible: true, uniqId: new Date().getTime());

I show the modal when I get the visible prop (sent when using the refresh action).
I noticed that If I do not send a new prop value (this is why I use the date timestamp), it doesn't go to componentWillReceiveProps and then doesn't re-render.
