> ComboBox textInput not cleared when dataprovider changes
> --------------------------------------------------------
>
> Key: FLEX-25906
> URL: https://issues.apache.org/jira/browse/FLEX-25906
> Project: Apache Flex
> Issue Type: Bug
> Components: Spark: ComboBox
> Affects Versions: Adobe Flex SDK 4.1 (Release)
> Environment: Affected OS(s): All OS Platforms
> Affected OS(s): All OS Platforms
> Browser: Firefox 3.x
> Language Found: English
> Reporter: Adobe JIRA
> Assignee: Justin Mclean
> Labels: easytest
> Fix For: Apache Flex 4.11.0
>
>
> Steps to reproduce:
> 1.Create a UI containing a spark ComboBox whose dataprovider can change based
> on user interaction
> 2.Select an item from the combobox
> 3. Change the dataprovider for the combobox to a collection that does not
> contain the selected item. For example if the selected index was 4 change the
> dataprovider to a collection with a length of 3 or less.
>
> Actual Results:
> The selectedIndex and selectedItem properties update as expected but the text
> in the textInput still displays it's original value.
>
>
> Expected Results:
> The text property of the textInput should be cleared or set to null if
> selectedItem is no longer valid.
>
>
> Workaround (if any):
>
> The problem is caused by the fact that the change to the dataprovider causes
> selectedItem to become undefined before the updateLabelDisplay() method of
> ComboBox is called. This will result in displayItem being undefined and thus
> prevent the update to textInput.text on line 677.
> The workaround is to create a component that extends ComboBox and override
> the commitProperties() function. In the overridden function, check if
> selectedIndex == -1 and if so manually set the text to "" before calling
> super.commitProperties.
