Justin Mclean updated FLEX-33282: --------------------------------- Labels: perfomance (was: ) > 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 > Labels: perfomance > > 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. -- This message is automatically generated by JIRA.
