--------------------------------------
Summary: Performance with TextArea using TLF
Key: FLEX-34247
URL: https://issues.apache.org/jira/browse/FLEX-34247
Project: Apache Flex
Issue Type: Bug
Components: Spark: TextArea
Affects Versions: Apache Flex 4.12.0
Environment: Win 7 64 Bit, FP 13
Reporter: Benjamin Ludwig
I run into performance issues with TextArea with Apache Flex 4.12.
After pasting a text of approx. 400000 chars into TextArea, it freezes for some
time but becomes responsive again. Then I noticed the follwing:
In Flex 4.6: I can enter chars into TextArea at any speed without any problems.
In 4.12: the FlashPlayer freezes on each char entered for some time, rendering
TextArea for long texts unsable.
I know there is much effort in TLF, but this feels like a downgrade, because
handling huge texts in a very fast way was my reason to choose TLF, but this
was about 2 years ago.
Do I now have to stay on tlf 1.0 for handling huge texts? Would be sad :(
regards
benny
