RE: Data Binding problem

[Yishay Weiss]

As I understand it the bead you use depends on your document type. If your root 
tag were a View you would use ViewDataBinding. I’m not aware of performance 
differences but I wasn’t involved in writing Binding so others may want to 
comment.

Hello Yishay, thank, with ApplicationDataBinding work !
I understand that I can shorten the level of "binding", so I am trying to use 
"ViewDataBinding" without success
Is it recommended to use "ApplicationDataBinding"? or is less performant



Thank very much.
Gustavo.

Hello.

I do not find what the concept of error is because it does not work "binding" 
from the beginning, but in the method refresh  .
Don't load the data for default.
