-----------------------------------
Summary: DateSpinner and SpinnerList scrolling behavior
inaccurate/broken
Key: FLEX-34749
URL: https://issues.apache.org/jira/browse/FLEX-34749
Project: Apache Flex
Issue Type: Bug
Components: Mobile: DateSpinner, Mobile: SpinnerList
Affects Versions: Apache Flex 4.12.1, Apache Flex 4.13.0, Apache Flex 4.14.0
Environment: Windows 7 64Bit, Flex 4.14.0, AIR 16
Reporter: Jan F. Weber
Priority: Blocker
The scrolling behavior of the DateSpinner and SpinnerList is very
inaccurate/broken and does not correctly snap to the nearest list entry after
the user has finished scrolling. This happens in most of the use cases. In
fact, the lists spin up or down approximately between 3 to 10 entries,
depending on the scroll direction.
This seems to be an issue with the throw velocity, which obviously is
miscalculated. The effect occurs especially when the mouse or touch-release
happens outside of the components bounds. Waiting a few seconds after spinning
before releasing does not make any difference.
You can use this example to see the inaccuracy/spinning afterwards after
releasing in action:
