bug: $ionicSlideBoxDelegate.next() causing an exception after upgrading to 1.0.0

[ericraio]

Type: bug

Platform: mobile webview

I just upgraded to 1.0.0 yay me but this is the only thing I can't figure out.

When calling any function that moves to the next slide such as this one

$ionicSlideBoxDelegate.next()

This is the exception that I get...

TypeError: Cannot read property 'length' of undefined
    at circle (http://localhost:8100/vendor/ionic/js/ionic.bundle.js:8050:21)
    at slide (http://localhost:8100/vendor/ionic/js/ionic.bundle.js:8079:14)
    at ionic.views.Slider.ionic.views.View.inherit.initialize.slide.select (http://localhost:8100/vendor/ionic/js/ionic.bundle.js:8432:7)
    at http://localhost:8100/vendor/ionic/js/ionic.bundle.js:105:46
    at Array.forEach (native)

when diving into the code, the slides variable gets undefined.

Could you demonstrate this in a codepen?

I have exactly the same problem since I upgraded to 1.0.0 with $ionicSlideBoxDelegate.next() and $ionicSlideBoxDelegate.slide(to)

@dellheng Your codepen is working!? I dont see the TypeError in your example? I am also struggling to reproduce this in a codepen example, however, I can confirm that I get the "undefined slides" after rc3 in my project.

[dellheng]

@hur0n Sorry I didn't say how to click button,It's very strange。 You didn't see error in this order:

1. click "Show images from start" button
2. click "Show second imagen"

You will see error in this order:

1. click "Show second imagen"
2. click "Show images from start" button

and the error only appear in first time ,you click again，the error won't appear

[dellheng]

@hur0n This is rc3 demo http://codepen.io/dellheng/pen/mJMzvR It's OK

+1 I have the same issue when I upgraded to ionic 1.0.0

trying to call:

$ionicSlideBoxDelegate.next()

It gives an exception:

TypeError: Cannot read property 'length' of undefined

+1, breaks on next(), previous(), slide(). Can someone reopen this issue? Downgraded to RC3.

[JavierMartinz]

+1 breaks with slide() on 1.0.1

[karthikiyengar]

Reopened as #4041

I'm having the same issue and myself and my team can't figure out how to fix this. Anyone have an example of how to get around this bug in 1.0.1/1.1?

Thanks!

I get the same issue using $ionicSlideBoxDelegate.next();. It seems that adding delegate-handle="slider" to the <ion-slide-box> in the template and referencing it using $ionicSlideBoxDelegate.$getByHandle('slider').next(); and $ionicSlideBoxDelegate.$getByHandle('slider').previous(); work reliably in 1.1.0 though

[karthikiyengar]

JunkMyFunk - your solution does not seem to work for me, although I found an ugly-hack way to fix it using a timeout (v1.1.0).

$timeout(function() {
    $ionicSlideBoxDelegate.$getByHandle('photos').slide(index);
},   100);

[RameshJhajharia]

Getting same issue at $ionicSlideBoxDelegate.next();. The strange thing is that it is working at one place in my app but not working in another app.

[rajeshwarpatlolla]

+1 Same issue even after trying the above solutions.

[marlonmantilla]

Having same issue here too, neither of the solutions above worked for me.
