Hi..I have an implemented project inTurkish made by flex 3 and now i want to convert whole frontend into Arabic. I am not sure to migrate to flex 4 since it has not an official release. I tried Flaraby but it does not fullfill my requirements. I need mirrored components, especially tree control. I was ready to pay for these if someone is selling these. Unfortunately, i found nothing on net except from TLF and Gumbo. If ı use gumbo, it is likely that i will have lots of problem since there are more thsn 50000 lines of code in my project. Does TLF work in rendering arabic texts right to left when the text come from a servlet?
Regarding the mirrored components, it's planned for Gumbo but I think Adobe didn't yet start implementing this feature. So it wouldn't help to migrate to Gumbo for now.
I advise to use TLF for text and implement the component mirroring manually on a case by case basis. Especially for complex components like the tree control, you can see for example if you really need the folding functionality and if not, you could implement your own 'simple' mirrored tree.
