    [ https://issues.apache.org/jira/browse/FLEX-33935?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13832530#comment-13832530 ] 

Andrey Fel commented on FLEX-33935:
-----------------------------------

When change event is dispatched DropDownList.enabled is set to false. It invalidates the skin, but the skin is not redrawn, updateDisplayList is not called for the skin.
