SelectBooleanRadio not showing properly with readonly EL

Question

Hi,
I'm trying to implement a group of selectBooleanRadios that the value or selected value is a read-only EL.
Like:
<af:iterator value="#{backBean.items}" id="id0"
var="row">
<af:panelGroupLayout>
<af:selectBooleanRadio group="items" label="#{row.name}"
simple="true" text="#{row.name}"
value="#{row==backBean.targetItem}" id="sbr2">
</af:selectBooleanRadio>
</af:panelGroupLayout>
</af:iterator>
But it seems the selectBooleanRadio select radio disappear (instead of unselected) when the #{row==backBean.targetItem} value is false.
In the ADF faces says: If the EL binding for the "value" points to a bean property with a getter but no setter, and this is an editable component, the component will be rendered in read-only mode.
Is this a case of this sentence? Say:EL with comparison will be considered as read-only and the selectBooleanRadio will never take in any input?

Answer 1

that is correct. if there is no setter, then the user will not be able to change the value
