---------------------------------
Labels: easyfix easytest (was: )
> ListBase.value getter throws runtime error #1069 if data provider objects do
> not have "data" property
> -----------------------------------------------------------------------------------------------------
>
> Key: FLEX-17312
> URL: https://issues.apache.org/jira/browse/FLEX-17312
> Project: Apache Flex
> Issue Type: Bug
> Components: mx: DataGrid, mx: List
> Affects Versions: Adobe Flex SDK 3.2 (Release)
> Environment: Affected OS(s): All OS Platforms
> Affected OS(s): All OS Platforms
> Browser: Safari
> Language Found: English
> Reporter: Adobe JIRA
> Priority: Minor
> Labels: easyfix, easytest
>
> Steps to reproduce:
> 1. Populate the data provider for a List or DataGrid with objects of a sealed
> (non-dynamic) class without a "data" property
> 2. Select an item in the list or grid
> 3. Attempt to read the "value" property of the list or grid
>
> Actual Results:
> ReferenceError: Error #1069: Property data not found on [class name] and
> there is no default value.
>
> Expected Results:
> Should not throw an error
>
> Workaround (if any):
> - Add a "data" property to the class used to populate the list (or make the
> class dynamic), or:
> - Subclass list or grid so that the value getter checks for "data" property
> before trying to read it
> I've attached two code files in Archive.zip that reproduce this.
> The problem seems to be this line of code in ListBase.get value():
> return item.data != null ? item.data : item.label;
> I'd guess it needs a check like: if (item.hasOwnProperty("data"))...
