Flex4.6 mobile maxChars bug/problem and workaround

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.)
flash.text::StageText/set viewPort [no source]

However setting maxChars to something much smaller (e.g. 10) was fine. 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:


id        ="textInputId"
maxWidth  ="{skinableContainerId.width}"
maxChars  ="512" />


The future of Flex :
