----------------------------------------
Summary: Setting the text of a spark TextArea cause a script
timeout error
Key: FLEX-34081
URL: https://issues.apache.org/jira/browse/FLEX-34081
Project: Apache Flex
Issue Type: Bug
Components: Spark: TextArea
Affects Versions: Apache Flex 4.11.0
Environment: Windows. Firefox, IE, Chrome, FP 11.9, FP 12
Reporter: Alexander Scheibe
Attachments: FontCrash.fxp
Steps to reproduce: compile the attached FXP project
Description:
The test application contains a text area of a specific width and height and a
font size of 14. The application also contains three embedded fonts: Myriad
Pro, Rosario, Source Sans Pro and two buttons to set a 'critical' string.
Using the first button to set the 'critical' string of 85 characters length,
the application will become unresponsive and will end with error #1502 "A
script has executed for longer than the default timeout period of 15 seconds."
In most cases the stack trace shown in the debug player shows that work is
going on in the StandardFlowComposer, but since this is a timeout error it may
stop anywhere.
When using the second button only the first 84 characters of the 'critical'
string are set which does not cause the error for the fonts Myriad Pro and
Source Sans Pro. Also one can see that 84 characters do not create a scroll
bar. Moreover it is possible to type in the 85 character 'f' without problems
and the text area will show the vertical scroll bar.
Additionally setting the text programmatically when the text area already shows
a scroll bar does no cause the error either.
So for me it looks like certain font dimensions can cause the TLF to loop in
circles when it comes to point to where a text area will show a scroll bar
