Summary: Fatal errors in TextBlock after pasting text of specific
length in TextArea
Key: FLEX-34649
URL: https://issues.apache.org/jira/browse/FLEX-34649
Project: Apache Flex
Issue Type: Bug
Components: Spark: TextArea
Affects Versions: Apache Flex 4.12.1
Reporter: Mihai Chira
Assignee: Mihai Chira
*Steps to reproduce*:
# Compile and run the attached project
# Click on the TextArea and press Ctrl+HOME
# Paste this text, _including the empty line at the end_: {noformat}This
sentence needs to wrap with one or two characters like: w
{noformat}
# Press either
## DELETE
## LEFT
*Desired behaviour*: (for DELETE) the space is deleted without a fatal and (for
LEFT) the cursor moves left without an error.
*Actual behaviour*:
# DELETE: {noformat}TypeError: Error #1009: Cannot access a property or method
of a null object reference.
