iron-list scroll interaction with child element tap

[Jim Trainor]

I created an iron-list that has a paper-ripple, with a tap event handler, on each child list element. On desktop browsers the scroll action and tap actions are distinct so I can scroll the list without causing ripples and tap events on list items.  On touch devices I cannot scroll the list without also triggering ripple animations and tap events on the list items at the point where the scroll gesture starts on the iron-list. 

The tap event on the list element is undesirable when the touch was for the purpose of scrolling the list (i.e. was actually a swipe).

I don't have much experience with these sort of issues and I'm not sure if this something that needs to be improved in Polymer or if this is something that I sort out in my own application. Anyone have any thoughts?

Hey Jim,

It sounds like an issue, I can repro this issue.  What do you think Dan?

This is fixed in master with https://github.com/Polymer/polymer/pull/2134, and will be released with the next version of Polymer.

Oh, this might be seperate, since that PR is for the track gesture.

You can disable all gestures on vertical scrollable areas by using this API: element.setScrollDirection('y'), and horizontal with setScrollDirection('x')

Without that, I can't tell if your touches are for scrolling or gestures.
