Problem with "required" attribute in inputBox

Question

Hi ,
I have a requirement where a input field needs to be populated using lookup.
I am using commandButton to populate the input field.Since I dont want user to type anything in this input Field , I have made this field readOnly.
This is a mandatory field so I have put required attribute true.But on the click of submit button this validation does not trigger.If I make remove readOnly attribute or make it false, the validation triggers.Here is the snippet for this part.
<afh:rowLayout>
<afh:cellFormat halign="right" >
<af:commandButton id="lookupFrom_buttonId" text="From Mfg:"
action="dialog:company.selectBox"
immediate="true" windowWidth="390" windowHeight="550"
launchListener="#{mfgReassignBean.addParameter}"
returnListener="#{mfgReassignBean.returnFromMfr}"
partialSubmit="true" useWindow="true"
>
</af:commandButton>
</afh:cellFormat>
<af:inputText
partialTriggers="lookupFrom_buttonId"
readOnly="true"
required="true"
binding="#{mfgReassignBean.fromDeveloperInput}"
value="#{mfgReassignBean.assignmentRule.fromMfgName}"
/>
</afh:rowLayout>
has anybody faced such situation...any suggestions ?
Thanks!!

disabled and readonly fields are discarded from the JSF stack and thus not validated! Options are: make readonly field not readonly on form submit or copy readonly field to hidden field (both involve client side javascript)
