@zwz Looks like we’re talking about 2 different things in here. I commented on both yesterday, and I don’t think they’re related to one another…
One is the width thing, that has been present since beta.2 I think. The other one is the undefined is not a function, that I explained in details here. Now, thank you because you’ve just provided the test case that @andy asked for to reproduce that bug.
As for the bug mentioned in this thread, any of the starter projects generated by ionic will sufice.
