Bug-note to self, and workaround while waiting for the bug-base to migrate from Adobe to Apache.
I’m using in a Flex 4.6 mobile project and found that setting the maxChars property to 512 caused exeption:
Main Thread (Suspended: ArgumentError: Error #2006: The supplied index is out of bounds.)

From experimentation, seems that the biggest number to which maxChars could be set without causing the problem was 481. I have no idea what that number relates to. Anyway the database field my TextInput corresponds to is 512 chars max so that’s the number I need.
The workaround:
Setting maxWidth on the TextInput seems to solve the problem. But rather than insert a constant I want the TextInput to flex to the width of it’s container, so the following seems to avoid the problem:
<s:TextInput
id ="textInputId"
maxWidth ="{skinableContainerId.width}"
maxChars ="512" />The future of Flex :
why the fuck does this happen on the AIR 3.2 release build. I am getting it too 🙁
