TextArea loading from a file

[Aanjaneya Shukla]

Hi,
I am trying to load a text file from json into the window as
JSON:
{
Text:"@sample.txt"
}
BXML:
<TextArea text="%Text"/>

So instead of loading the text into the TextArea from the file sample.txt, it 
only it shows '@sample.txt' as the text in the TextArea. 

Same logic works fine for images.

Thanks
