Are both getters and setters mandatory in JSF's managed beans?

Question

I have a JSF component which is initialized from a managed bean's getter getProperty(). Is it mandatory to also have a setter setProperty() in that managed bean?

Answer 1

It depends.

Some property bindings must be read-write. For example, if you bind the value of a component that implements EditableValueHolder. Other properties can be read-only.

If you use the binding attribute for dynamically creating component instances, this must also be read-write as per the contract defined in the specification.
