jsf inputText disabled and readonly properties in form

This question is a follow on from a previous question "InputText value null when disabled is true" however I can not add comments to it.

I am using jsf 2.2 and the both the disabled and readonly properties when set true, for the inputText and inputTextarea controls when included in a form is deleting data from the associated field in the database when the object is merged because the fields are null when the object is returned from the jsf page.

The purpose for setting these properties on a form's field is to display the data in the field but not allow the user to change it and save changes to other fields in the form.

What other way can this be achieved other than placing the fields outside of the form and complicate the page layout.
