I got this Error in onsen carousel…

Uncaught TypeError: Cannot read property ‘0’ of null
Class.extend._getCarouselItemElements @ onsen.js:7202
Class.extend._getCarouselItemCount @ onsen.js:7327
Class.extend.getActiveCarouselItemIndex @ onsen.js:6916
(anonymous function) @ script.js:661

i’m using this function for auto carousel …if i navigate to other pages i got this error repeatedly…

setInterval(function() { 
var index1 = loginslider.getActiveCarouselItemIndex();
 if (index1 >= 4) { loginslider.first(); } 
 else { loginslider.next(); } }, 6000); 

Thanks…i will check…

Hi,
How to add color in active menu item using Ons-navigator…

@Fran-Diox It’s working thanks…

I am currently building my first cordova app with onsen ui. Looks promising so far! But I ran into a problem I could not solve and I could not find the answer.
I hope it is a beginner question and can be solved easily by someone with more experience with onsen.
I want to have a sliding-menu and still the “usual” navigation on the main screen.
Two different approaches I tried:

<ons-navigator var="app.navi">
<ons-page>
<ons-sliding-menu menu-page="menu.html" main-page="page1.html" side="left"
var="menu" type="reveal" max-slide-distance="260px" swipable="true">
</ons-sliding-menu>
</ons-page>
</ons-navigator>
<ons-template id="menu.html">
<ons-page modifier="menu-page">
<ons-list-item class="menu-item" ng-click="menu.setMainPage('page2.html', {closeMenu: true})">
Continue last story
</ons-list-item>
...
</ons-page>
</ons-template>
<ons-template id="page1.html">
<ons-page ng-controller="BooksCtrl">
// Navigation in controller:
app.navi.pushPage("new_action.html", {
animation: "lift"
});
</ons-page>
</ons-template>

Result: No error messages. But once I navigate from the first main-page to another page I can’t open the sliding menu. (Same as in the official demo found in github repo called navigator_sliding-menu)

<ons-sliding-menu menu-page="menu.html" main-page="page1.html" side="left"
var="menu" type="reveal" max-slide-distance="260px" swipable="true">
</ons-sliding-menu>
<ons-template id="menu.html">
<ons-page modifier="menu-page">
<ons-list-item class="menu-item" ng-click="menu.setMainPage('page2.html', {closeMenu: true})">
Continue last story
</ons-list-item>
...
</ons-page>
</ons-template>
<ons-template id="page1.html">
<ons-navigator animation="slide" var="app.navi">
<ons-page ng-controller="BooksCtrl">
// Navigation in controller:
app.navi.pushPage("new_action.html", {
animation: "lift"
});
</ons-page>
</ons-navigator>
</ons-template>

Same as here: http://codepen.io/argelius/pen/ogXGeV
So the navigation element is moved to the first main-page.
Result: I can navigate through the app (via pushPage in controller) and I can open the menu from every page. But once I click a link in the menu any pushPage calls result in the error messages:
angular.min.js:108 TypeError: Cannot read property ‘$new’ of null

Any ideas?
Thank you in advance
