Unable to set selected default tab

[boyaq]

Hi,

We've tried to make a default tab using "selected" props of Router like this: (this is part of your example"

<Router selected={"tab5"} footer={TabBar} showNavigationBar={false}>
    <Route name="tab1" schema="tab" title="Tab #1" >
        <Router onPop={()=>{console.log("onPop is called!"); return true} }>
            <Route name="tab1_1" component={TabView} title="Tab #1_1" />
            <Route name="tab1_2" component={TabView} title="Tab #1_2" />
        </Router>
    </Route>
    <Route name="tab2" schema="tab" title="Tab #2" hideNavBar={false}>
        <Router onPop={()=>{console.log("onPop is called!"); return true} }>
            <Route name="tab2_1" component={TabView} title="Tab #2_1" />
            <Route name="tab2_2" component={TabView} title="Tab #2_2" />
        </Router>
    </Route>
    <Route name="tab3" schema="tab" title="Tab #3" component={TabView} hideTabBar={false}/>
    <Route name="tab4" schema="tab" title="Tab #4" component={TabView} />
    <Route name="tab5" schema="tab" title="Tab #5" component={TabView} initial={true}/>
</Router>

Here I set the selected tab.

<Router selected={"tab5"} footer={TabBar} showNavigationBar={false}>

after this I got error like this:

cannot read property 'dispatch' of undefined in Actions.js @ 70:0

So after a lot reading and debugging I found out that it executes "Tabs onSelect function" on first render which I think it shouldn't, as it SHOULD only fires after user tap on the tab icons.

When it executes the onSelect function when rendering, the Actions currentRouter doesn't have the ExRouter as delegate, it remains as RouterDelegate which throws that 'dispatch' error.

So for now, i just added following line to my copy of TabBar's onSelect function to fix it temporarily.

if(Actions.currentRouter.delegate.constructor != ExRouter){ return {selected: true}; }

Hope you can look into it and let me know if there is a solution.

Thanks

Hi Aksnov,

As I mentioned in #238 , My problem is slightly different and will appreciate if you can look into it.
