Please, provide the details below:

Tell us about the problem

Please, ensure your title is less than 63 characters long and starts with a capital letter.

Which platform(s) does your issue occur on?

Please provide the following version numbers that your issue occurs with:

Please tell us how to recreate the issue in as much detail as possible.

  1. Start the application ..
  2. Tap an item --> This works as expected
  3. Tap the item again --> Event not fired

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

I've located the problem in line 833 of ui-listview.ios.js. There you find the following code fragment

if (currentIndexPath && touchEvent.tapCount === 1) { if (owner.hasListeners(commonModule.RadListView.itemTapEvent)) { var args = { ios: touches, eventName: commonModule.RadListView.itemTapEvent, object: owner, view: this.myContentView, index: owner._getIndexForIndexPath(currentIndexPath), groupIndex: currentIndexPath.section }; owner.notify(args); } }

As you can see the event is only fired when tapCount equals 1. What is the idea behind this line? If there is none, can it be removed?

So I stumbled upon this problem; It got me stumped for a while. Last Thursday I provided a possible solution but it seems like this was not a viable solution after all.

The real source of the problem was that I was wrapping touch events on higher level elements in my template.

I am unsure of the reason why this is not supported in ios but removing my @touch event resolved it.
