[JSF] Should I initialize components in their getters.
Hi,
JSF components getters (getter methods of instances that are EL bound to JSF components in the JSPs) are called only during initial requests and I presume that they are used by the JSF framework to synchronize the JSF view tree on the server with the instances on the Backing beans (i.e. Both the tree and the Backing bean should refer to the same instances of components).
Now is it ethical / correct to set initial values to a component in their getter methods?
Thanks,
Dushyant

Dushyant,
Sorry -- It's usually easier to set UI component properties in the setter
methods, as the JSF implementation has already created the instance of the
component for you. Otherwise you'll have to create the component instance
yourself, which normally isn't necessary.

Dushyant,
Sure, it's safe to set properties in the getter methods.
