-----------------------------------
Summary: ComboBox not closed when selecting an item from the
dropdown list under certain conditions
Key: FLEX-34019
URL: https://issues.apache.org/jira/browse/FLEX-34019
Project: Apache Flex
Issue Type: Bug
Components: Spark: ComboBox
Affects Versions: Apache Flex 4.11.0
Reporter: Tamás Nepusz
Priority: Minor
The dropdown of a Spark ComboBox is not closed when an item is selected from
the dropdown list if the selection triggers a binding that sets the "enabled"
property of the ComboBox to "true" (even though the property was "true" before
since otherwise one could not have opened the dropdown).
This happens because the setter of the "enabled" property in the ComboBox class
is directly inherited from SkinnableComponent, which calls
invalidateSkinState() unconditionally (i.e. even if the new value of the
"enabled" property is the same as the old value). I managed to work around the
issue by overriding the setter of "enabled" in my custom ComboBox class and not
calling the setter of the superclass if the old value is equal to the new one.
