> Advanced Data Grid throwing script error
> ----------------------------------------
>
> Key: FLEX-33475
> URL: https://issues.apache.org/jira/browse/FLEX-33475
> Project: Apache Flex
> Issue Type: Bug
> Components: Advanced Data Grid
> Affects Versions: Adobe Flex SDK 4.6 (Release)
> Environment: Windows
> Reporter: rishi raj tripathi
> Labels: patch
>
> Hello,
> We have been using Flash builder 4.6 with SDK 4.6.0 for our development
> purposes since the last couple of years. While using it, we have observed one
> issue with the use of Advanced Data Grid containing hierarchical data.
> Broadly our observation is that if the grid contains a large result set with
> hierarchical data, then on expanding and collapsing the items repeatedly, the
> following error is thrown
> TypeError: Error #1010: A term is undefined and has no properties.

> mx.controls.listClasses::AdvancedListBase/mouseMoveHandler()[E:\dev\4.y\frameworks\projects\advancedgrids\src\mx\controls\listClasses\AdvancedListBase.as:9374]
> On investigating the case further we have found out that the problem is due
> to a function called ‘itemRendererToIndices’ in the AdvancedListBase.as file
> of the SDK. A wrong row index is computed which in turn causes the error. Can
> you please provide us support for this problem. If so, what is the procedure
> we need to follow.
