[FLEX-34717] #1009 RTE in SpellUI.cleanUp when disabling spelling before dictionaries finish loading

• Type: Bug
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Affects Version/s: Apache Flex 4.13.0, Squiggly 1.1
• Component/s: Squiggly
• Assignee: Mihai Chira

Description

Steps to reproduce: Run the attached application and click on the button twice, in quick succession. This simply calls SpellUI.enableSpelling() on a TextArea, and then SpellUI.disableSpelling() on the same text area - and all this happens before the dictionary has time to finish loading.

Error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
