----------------------------------
Summary: DropDownList Issues on Mobile
Key: FLEX-35383
URL: https://issues.apache.org/jira/browse/FLEX-35383
Project: Apache Flex
Issue Type: Bug
Components: Spark: DropDownList
Affects Versions: Apache Flex 4.16.1
Environment: Developing in Flash Builder 4.7 on Windows 10 using Flex
4.16.1 SDK and AIR 28 for iOS
Reporter: Bill Spence
In Flash Builder 4.7, and designing for mobile iOS apps(paraticularly the
iPad), the DropDownList behaves erratically. If you tap on the DropDownList so
that the list opens, and then flick your finger across the list, it scrolls
just fine.
The problem arises when you put your finger on the list and then scroll slowly
up or down the list. When you release your finger from the list, wherever your
finger was when you lift it gets selected every, single, time and the list
closes. Once scrolling begins, you should not be able to select an item and
close the list unless you tap the list a second time. Lifting your finger after
scrolling should not result in a selection.
This leads to a bad user experience because the dropdownlist feels like it is
randomly closing. It is hard to scroll through moderate length lists. If you
flick the list it usually scrolls too far, if you then try to scroll more
deliberately and exactly, the list closes before you get to the right item. It
feels way too hard to select the item that you want.
