Lazy property doesn't work on tab

[ValentinBlokhin]

Version

Tell us which versions you are using:

• react-native-router-flux v4.0.0-beta.21 (v3 is not supported)
• react-native v0.47.2

Expected behaviour

Tab should be lazy loaded.

Actual behaviour

Tab information loads immediately on application load.

Steps to reproduce

I'm using this code:

<Scene
            key="one"
            tabs
            tabBarComponent={TabBarBottom}
            duration={1}
          >
            <Stack
              key="scene1"
              icon={MessageTab}
              title="scene1"
              hideNavBar
              lazy
            >
              <Scene
                key="subscene1"
                component={Subschene1}
                lazy
                title="subscene1"
                hideNavBar
              />
 </Stack>
 </Scene>

It is first tab, what do you expect? It will be loaded because it is first.

[ValentinBlokhin]

It's not first tab, I removed some tabs from code example, it's 3 tab

[aksonov]

lazy doesn't work for containers, only for scenes - check lazy docs for TabNavigator (react-navigation).

lazy doesnt work for me, I've set it up in a scene and it's not working....

<Scene lazy key="auth" component={Auth} title="Facebook login"/>

[digitaldavenyc]

@aksonov lazy doesn't seem to be working for Scenes either, there's a duplicate issue open on it: #2846

Just to be clear, this should work right?

<Stack key="messages"
	icon={MessagesTab}
>
	<Scene key="messages"
		title="Messages"
		component={Messages}
		lazy={true}
		initial={true}
	/>
	<Scene key="channel"
		component={Channel}
		hideNavBar={true}
		hideTabBar={true}
	/>
</Stack>

Anyone else experiencing this? It's causing some serious performance problems for us

Yeap doesn't work properly, I'm guessing. Just in case, this is my code
Doesn't load on initial refresh, but keeps loading when navigating to a sister route. When I navigate to home, the friends component is mounted. I even tried adding tabs to all scenes. Still doesn't work. Please let me know if anyone finds a solution to this.
<Provider store={store}> <RouterWithRedux> <Scene key="root"> <Scene tabs={true} tabBarComponent={BottomNavigation} tabBarPosition="bottom" lazy={true} > <Scene key="profile" path="/profile/:userId" component={PostProfileContainer}/> <Scene key="reviewers" path="/reviewers/:userId" component={ReviewersProfileContainer} title="Reviewers" back={true}/> <Scene key="home" component={HomePageContainer}/> </Scene> <Scene key="signUp" component={SignUp} title="SignUp"/> <Scene key="traitsSelect" component={TraitsPageContainer} hideNavBar/> <Scene key="landing" component={LandingPageContainer} hideNavBar/> </Scene> </RouterWithRedux> </Provider>

Hey animationEnabled={false} worked for me.

[digitaldavenyc]

@Samesh I tried adding animationEnabled={false} to a <Stack> and doesn't fix anything.... I'm getting so frustrated by this debating ripping out RNRF and just using React Navigation straight up

`


<Stack key="createPost" hideNavBar titleStyle={{ alignSelf: 'center' }}>
<Scene
key="createPostModal"
component={CreatePostSelectType}

onLeft={Actions.pop}

                <Scene key="root">
                    <Scene hideNavBar panHandlers={null}>
                        <Tabs
                            key="tabbar"
                            showLabel={false}
                            tabBarComponent={BottomNavigation}
                            tabBarPosition="bottom"
                            animationEnabled={false}

                                <Scene key="notifications" component={NotificationsContainer} title="Notifications"/>
                                <Scene key="singlePost" component={SinglePagePostContainer}/>
                                <Scene key="pendingComments" path="/pending_comments/:postIdParam" component={PendingCommentsContainer} title="Pending comments" hideTabBar/>
                                <Scene key="search" component={SearchPageContainer} navBar={SearchNavBar}/>
                                <Scene key="profile" path="/profile/posts/:userIdParam" component={PostProfileContainer}/>
                                <Scene key="reviewers" path="/profile/reviewers/:userIdParam" component={ReviewersProfileContainer} title="Reviewers"/>
                            </Stack>

                        </Tabs>
                        <Scene key="signUp" component={SignUp} title="SignUp"/>
                        <Scene key="traitsSelect" component={TraitsPageContainer} hideNavBar/>
                        <Scene key="landing" component={LandingPageContainer} hideNavBar/>
                    </Scene>
                </Scene>

                </Modal>
            </RouterWithRedux>
        </Provider>`

This is what works for me @digitaldavenyc. I don't really understand well as to how this works either but one thing is that the first nested route is rendered initially.

Not working for me neither. Trying to implement RAM Modules and this is a bottleneck in performance.
