| Steps to Reproduce: |
Steps to reproduce bug:
- create a new Flex app
- add a TextArea control
- size the TextArea control to 50 px wide by 200 px high
- doubleclick on the TextArea control and type some text (at least one hundred chars)
- add a button to the app
- add a click handler for the button
- in the click handler check the textWidth and textHeight of the TextArea control (trace them out)
- run the app
- click on the button to check the textWidth and textHeight Properties
Results:
The values returned in the trace are not accurate.
Expected results:
Accurate results. Validation should have already happened (since the text is rendered on the screen)
Also repros if:
you set the "TextArea.text" property at runtime, call validateNow on the TextArea and then check textWidth and textHeight.
The only time the correct values are returned is if:
- you type something in the TextArea control at runtime and then check the values
- you set the htmlText property programmatically, call validateNow, and then check them

TextArea.textWidth and TextArea.textHeight do not return correct values when text is set in MXML.
Open
I've uploaded a bug file and sample source. This occurs because the text is being set in MXML. If you set the text on creationComplete, it works ok, so that could be considered a workaround. Able to reproduce in 2.0.1 and 3.0. We should fix this.
