How do i restrict textFlow to single...

Hi Flex people,

I'm trying to use the textFlow with Flex3 and having trouble using it with only one line (i'm trying to make component that will act as TextInput that can have RTL and LTR).

i implemented the textFlow component, but still got strange behaviour:

When i use it the regular way, it jumps to the second like when reaches the end (why),

and when i use it with lineBreak, it does not show the rest of the text.

Can someone know how can i make my component act like TextInput?

Thanks in advance,

Lior
