Thanks Alex. That was also my understanding. Regarding TextInput / TextArea, there is no issue with regard to RTL in using StageText ( embedded in StyleableStageText or ScrollableStageText) .
Now something strange that gets me puzzled. I did some experiments with mobile components that use TextField (actually StyleableTextField) and I managed to displayed Arabic/Hebrew (list , titles and nav bar) https://www.dropbox.com/s/4e4untcp3f4jeb2/List_arabic_LTR.png But this works only if the surrounding View or the application layoutDirection is set to "ltr". And indeed, you notice that the text is RTL but the layout is still LTR. Now, if I set layoutDirection to RTL either at the Application or View , then everything disappears: https://www.dropbox.com/s/jzu1veecjm64m51/list_Arabic_RTL.png I thought that layoutDirection = RTL was "merely" applying a mirroring transform to the display. I am confused.

You need TextLines for RTL. You may be able to swap in the "desktop" skins for TextInput/TextArea and pay the performance and memory hit to get RTL text, but then I'm not sure how well StageText will work with that, if at all. Essentially, the mobile team traded off RTL support for better performance. Now, that was several years ago and phones and tablets are faster, so it might be worth revisiting that decision. -Alex On 3/21/14 3:41 PM, "Maurice Amsellem" <maurice.amsel...@systar.com> wrote: >Hi Team, > >Ori Segal has reported a problem in TextInput default skin with RTL >(Hebrew, arabic) layout. >I have fixed this problem. > >Now he has reported a problem in TextInput "prompt" text not being >displayed in RTL. > >So I did a small test: set layoutDirection="rtl" to a sample mobile app >(with buttons, mobilegrid, etc..) and almost every text disappeared. > >The only texts that seem to be displayed correctly are: >- TextInput / TextArea with the default text (that is using native >StageText) >- spark Label, that is using TextLine (and the new FTE/TLF engine). >Everything else, that uses the mobile-optimized StyleableTextField, >will not display RTL (apparently because it's based on the old >TextField engine). > >Reading the articles below, it seems clear enough that RTL is NOT >supported on AIR mobile (with a few exceptions): > >http://sourceforge.net/adobe/flexsdk/wiki/Mobile%20Text%20Components/ >http://help.adobe.com/en_US/flex/using/WS02f7d8d4857b1677-165a04e112695 >1a2 >d98-7ffe.html >http://help.adobe.com/en_US/flex/using/WS02f7d8d4857b1677-165a04e112695 >1a2 >d98-7ffd.html > >Alex, as you seem to have been involved in that, do you confirm? > >Something else: >The first article says: >" Primarily for performance reasons and support for native predictive >text input and editing, mobile will use TextField-based text in all >critical areas.
