Method Detail

onConfigure
protected void onConfigure()
Description copied from class:Component
Called on all components before any component is rendered. This method should be used to configure such things as visibility and enabled flags.Overrides must call
super.onConfigure()
, usually before any other codeNOTE: Component hierarchy should not be modified inside this method, instead it should be done in
Component.onBeforeRender()
NOTE: Why this method is preferrable to directly overriding
Component.isVisible()
andComponent.isEnabled()
? Because those methods are called multiple times even for processing of a single request. If they contain expensive logic they can slow down the response time of the entire page. Further, overriding those methods directly on form components may lead to inconsistent or unexpected state depending on when those methods are called in the form processing workflow. It is a better practice to push changes to state rather than pull.NOTE: If component's visibility or another property depends on another component you may call
other.configure()
followed byother.isVisible()
as mentioned inComponent.configure()
javadoc.NOTE: Why should
Component.onBeforeRender()
not be used for this? Because if a component's visibility is controlled insideComponent.onBeforeRender()
, once invisible the component will never become visible again.- Overrides:
onConfigure
