Sorry, I don't know much about extjs and I can't help.
Would you please show more complete code? Such as textfield segment in template. Then anyone here can help you even though they are not familiar with extjs.
And you can debug the TextField component in your IDE to check what's the value submitted from client side. But first you need to down 5.0.11 source code.
Hope that would help.

Thanks!

DH

Try to introduce @Persist, like this:

@Persist
private String _formValue;
