[development] Form textfield data retreive

[Austin Einter]

Hi All
This issue is resolved.

While adding textfield, I used #value attribute, and that was causing issue.
Instead, if #default_value attribute is used, then I am able to retreive the
value.

So is it a expected behavior or something wrong.

Regards
Austin
