> XML item's parent null in item renderer when added to XMLListCollection
> -----------------------------------------------------------------------
>
> Key: FLEX-34283
> URL: https://issues.apache.org/jira/browse/FLEX-34283
> Project: Apache Flex
> Issue Type: Bug
> Components: Spark: List
> Affects Versions: Apache Flex 4.12.0
> Reporter: Frédéric Monjo
> Assignee: Nick Kwiatkowski
> Priority: Critical
> Labels: collections, xml
> Attachments: Tests.mxml

>
> Since 4.12, there seems to be a regression bug in XMLListCollection. The
> scenario is:
> # The user selects an item in a list and clicks a button to create a copy of
> this item below the selected one
> # Clone the item through {{item.copy()}}, make some modifications to this item
> # Add the item to the XMLListCollection using {{addItemAt}}, then call
> {{refresh()}} on the collection
> # Inside some item renderers (not obviously the cloned one), XML item's
> parent is null, and never get updated, which could cause runtime errors.
> Up to version 4.11, there has never been such problems. After a short
> investigation, this problem may be caused by a change in {{XMLListAdapter}}
> from [this
> commit|https://github.com/apache/flex-sdk/commit/59dd2be7f6a9b0fda745249cf979adeac7f406b7].
>
> Please find attached a sample program to reproduce the bug. Run the program,
> select an item and click on the "Duplicate after" button.
> When run in 4.11, you should see the following console trace :
> {code}
