---------------------------------------

             Summary: Slow performance when trying to null Array after copy & paste large data
                 Key: FLEX-34012
                 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


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.
