A working Approach, seems to be:

<f:for each="{patient.diagnosis}" as="oneDiagnosis"> 						

    <f:form.textbox 
name="patient[diagnosis][{oneDiagnosis.uid}][diagnosisName]" 
value="{oneDiagnosis.diagnosisName}"/>

    <f:form.hidden 
name="patient[diagnosis][{oneDiagnosis.uid}][__identity]" 
value="{oneDiagnosis.uid}"/>

</f:for>

Note that you add the hidden field "__identity" (where you give the 
uid), so that the values are updated not new children created.

Note also that "{oneDiagnosis.uid}" in 
"patient[diagnosis][{oneDiagnosis.uid}]..." is just a way to different 
between the childs. It's an identifier, like an array key not used for 
persistence. You could (as far as I understand - untested) use any 
iterating number.
