If any error in form submit, values are not retaining in the form

[mslabba]

While submitting a form, if form fields have some error, it will return with a validation error message, but the form doesn't retain the form values.

@mslabba : I didn't use set_value() function in form inputs. If you want to implement then you can change it at your end. I will update this thing in next release. Thanks, you gave me space for improvement.
