Struts html:text and the 'disabled' flag

Whenever using struts html:text tags, be careful with the 'disabled' flag. It may appear that it just disables the field for input, and indeed it shows the value in the form in the grayed-out field. In reality though, it is going to send a null value when you submit the form regardless of what seems to be the case.

Use the 'readonly' flag instead if you want a non-null value to be submitted.
