xml connector & textarea

Hello everybody!
I have a project where I use an xml connector with some textarea component. it works fine but I have a problem. I need the text area to be invissible and only the text that comes into it from an xml file should be vissible so I can see the background under the text.
I can achieve that with "myTextarea.setStyle ("borderStyle", 0);" but then I can only see 2 lines of the text in the text area and only in the left upper corner of the textarea. it's not using the whole textarea area.
I tried to use a dynamic textfield instead of the textarea component but it doesn't support bindings.
my question is:
1. is there any way to make the textarea component transparent or any other component for that matter?
2. any way to code bindings support for a dynamic textfield?

Thanks in advance!
Best regards, Marius
