Autoheight doesn't appear to do anything. I've doublechecked the installed textfield.swf plugin.
The correct attribute is autosize
Also for the new textfield, autoheight, it has a new behavior.
I was setting it to -1 , set the input, and reading out the height when it changed so that I can resize its container.
However, now it can change with a step in between, if they final height is 100, it may have gone to 16 before its finished. This prevents me from discovering when its finished and created an erratic race condition.
Usually, I read out the correct height, but it's not 100%.
Also, setting autosize true, from false causes the plugin to resize correctly, however, the height attribute is never upadated until the input changes.
