All you need is a resourcebundle containing the keys and text values, a selectcomponent to set the actual key and some java code in a valueChangeListener to search the resourcebundle for the key. So first create the resourceBundle file to hold the key/value pairs for the text resources. Next implement the page holding the selectcomponent, and an output component to show the value retrieved from the resourcebundle. 1: <af:panelGroupLayout id="pgl1"> 2: <af:selectOneChoice valueChangeListener="#{pageFlowScope.resourceBundleManager.listEntryChanged}" 3: id="soc1" autoSubmit="true" valuePassThru="true" 4: label="#{viewcontrollerBundle.SEL_RESOURCE_KEY}"> 5: <af:selectItem label="Value 1" val...

As a matter of fact this is possible. You can do this for the session only, or you can choose to persist these changes. In this post I first explain how to implement the "session only" functionality, and in the second part I explain how to use a persisted resource bundle with immediate refresh.

First of all you create a page that is used to hold components of which you want to change labels and prompts. Create two panelboxes next to each other. In the first one drop the employees collection and in the second one drop the child employees collection. Drop both as read only form. When browsing the first box, the second one will show the subordinate employees ...
