[jira] [Commented] (FLEX-27684) DropDownList selectedItem is ignored if dataprovider changes

["Justin Mclean (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLEX-27684?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13766107#comment-13766107 ] 

Justin Mclean commented on FLEX-27684:
--------------------------------------

Steps 2 and 3 should be swapped about.
1. Create a DrownDownList, binding a selectedItem and an arrayCollection to the dataprovider
3. Change the dataprovider
2. Change the selectedItem

Tested and working in Apache Flex 4.10.

>             Project: Apache Flex
>          Issue Type: Bug
>          Components: Spark: DropDownList
>    Affects Versions: Adobe Flex SDK 4.5 (Release)
>         Environment: Affected OS(s): All OS Platforms
> Affected OS(s): All OS Platforms
> Language Found: English
>            Reporter: Adobe JIRA

> Steps to reproduce:
> 1. Create a DrownDownList, binding a selectedItem and an arrayCollection to the dataprovider
> 2. Change the selectedItem (it is not in the dataprovider at this point)
> 3. Change the dataprovider, selectedItem is now in the dataprovider, but selected index is now -1
>  
>  Actual Results:
>  Nothing is selected
>  
>  Expected Results:
>  SelectedItem is in DataProvider, it should be selected.
>  
>  Workaround (if any):
>  Instead of binding against selectedItem, can bind selectedIndex with selectedIndex="{dataProvider.indexOf(selectedItem)}"
