             Summary: Performance issue with multiple item renderers 
                 Key: FLEX-33282
                 URL: https://issues.apache.org/jira/browse/FLEX-33282
             Project: Apache Flex
          Issue Type: Bug
          Components: Spark: DataGrid
    Affects Versions: Adobe Flex SDK 4.6 (Release)
         Environment: At least on mac
            Reporter: Petteri Tuovila


The problem is that the ItemRenderer's prepare is called for every visible 
ItemRenderer when the mouse is moved over the grid and when starting and 
finishing item editing. Of course that prepare function should be called when 
the renderers are first brought to stage at the initialization and when you 
scroll up or down outside the screen when the renderers are recycled. 

We are using datasets that well fit the screen with multiple columns so this 
can really make the program a little sluggish to use. When starting to edit 
there's easily a second or two delay before editor appears, after the indicator 
catches up with the mouse.
