-----------------------------------------
Summary: SkinnableTextBase steals focus by
callLater(textDisplay.setFocus)
Key: FLEX-34954
URL: https://issues.apache.org/jira/browse/FLEX-34954
Project: Apache Flex
Issue Type: Bug
Components: Spark: TextArea
Affects Versions: Apache Flex 4.14.1
Reporter: Konstantin Elstner
Priority: Critical
The support class:
spark.components.supportClasses.SkinnableTextBase
has a critical issue in line 1879:
callLater(textDisplay.setFocus)
The usage of call later will lead to possible focus losses in case of
environments with out mouse usage.
Examples:
- TextBox added to stage, afterwards a popup / alter is added
- TextBox is added and removed to / from stage
- Alert is opened over textbox, alert close will trigger switch to other
component, but text box will be reactivated for a short moment.
All this cases will have a critical focus loss.
Please change in spark.components.supportClasses.SkinnableTextBase
line 1879 to:
textDisplay.setFocus();
By the way:
A callLater workaround is a bad practice to fix some skin state issues,
especially only slow computers with possible dropped frames.
