> DropDownList inside a PopUpAnchor doesn't close when another DropDownList is
> selected
> -------------------------------------------------------------------------------------

> Key: FLEX-35125
> URL: https://issues.apache.org/jira/browse/FLEX-35125
> Project: Apache Flex
> Issue Type: Bug
> Components: Spark: DropDownList, Spark: PopUpAnchor
> Reporter: Mihai Chira
> Assignee: Mihai Chira
> Fix For: Apache Flex 4.16.0
>
> Attachments: Reproduce.mxml
>
>
> *Steps to reproduce*:
> # Run the attached code
> # Open the first DropDownList
> # Open the second DropDownList
> *Actual behaviour*: the first DropDownList is not closed.
> *Expected behaviour*: the first DropDownList is closed.
> *Notes*:
> * this is how it usually works when the components are not inside a
> PopUpAnchor
> * it relates to the DropDownLists not receiving the {{FocusEvent.FOCUS_OUT}}
> event when the other one is clicked, as ought to;
> {{DropDownListBase.focusOutHandler()}} is never called, even when the user
> clicks outside the application, whereas for DropDownLists on the stage the
> function is called for both these scenarios.
> * If we wrap the {{HGroup}} inside a {{TitleWindow}}, all works as expected.
> That's because {{TitleWindow}} implements {{IFocusManagerContainer}} and, as
> described in {{PopUpManager}}, "If the class implements
> {{IFocusManagerContainer}}, the window will have its own {{FocusManager}} so
> that, if the user uses the TAB key to navigate between controls, only the
> controls in the window will be accessed."
> * There is code in to keep the DropDownList open if the click was made on
> another DropDownList. This was implemented as a fix for FLEX-34088.
