Subject [jira] [Commented] (FLEX-34012) Slow performance when trying to null Array after copy & paste large data
Date Tue, 24 Dec 2013 00:49:50 GMT

    [ https://issues.apache.org/jira/browse/FLEX-34012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13856061#comment-13856061

Justin Mclean commented on FLEX-34012:
--------------------------------------

Changing selection has been greatly improved in 4.9 and 4.10 so this issue may of already
been fixed. (They may of course also be room for further improvements.)

>                 URL: https://issues.apache.org/jira/browse/FLEX-34012
>             Project: Apache Flex
>          Issue Type: Bug
>    Affects Versions: Adobe Flex SDK 4.6 (Release)
>            Reporter: Abhishek Dwevedi
>              Labels: easytest
>         Attachments: Main.mxml
>
>
> STEPS TO REPRODUCE:
> ===================
> 1. Run the attached Main.mxml
> 2. Click "Make Data (101 columns)"
> 3. Select all rows then click "Copy" 
> 4. Select all rows then click "Delete"
> 5. Click "Paste" 
> 6. Click "Delete Array"
> RESULT:
> =======
> Application would be halted for approximately 30 seconds.
> EXPECTED:
> =========
> Nulling Array should not take so much time. If you make data for 100 columns in the above
steps, the issue won't occur.
> WORKAROUND:
> ===========
> Not found yet.
> [Researched]
> ============
> * Using callLater() for nulling Array didn't help.
> * array = null is not helping
> * array.length = 0 is also not helpful.
