Hi, So the difference between getId() and getClientId() is that the last one generates the Id if necessary, am I right?
>From my point of view getId() is the getter for the id property which can be set with setId(). However, there is no method setClientId(). So I think the sence is that getId() returns non-null if the user assigned an id to the component and null otherwise, whereas getClientId() always returns a valid id, because it generates one if the component has no assigned id. So you are able to check if the user assigned an id to the component if the result of getId() is non-null. Nevertheless I don't know if that makes a lot of sence...
