I am trying to create a simple config page for my module but I am running into what seem to be localization issues. I am setting up the config panel similar to the “Home Connect” example. I have the following code in my gateway hook: [code] public static final ConfigCategory CONFIG\_CATEGORY = new ConfigCategory(“lrs”, “LRS.nav.header”, 750); ``` @Override public List getConfigCategories() { return Collections.singletonList(CONFIG_CATEGORY); } public static final IConfigTab LRS_CONFIG_ENTRY = DefaultConfigTab.builder() .category(CONFIG_CATEGORY) .name("lrs_manager") .i18n("LRS.nav.settings.title") .page(LRSSettingsPage.class) .terms("LRS settings") .build(); @Override public List getConfigPanels() { return Arrays.asList( LRS_CONFIG_ENTRY ); }[/code] ``` And the following class LRSSettingsPage.java [code]public class LRSSettingsPage extends ConfigPanel{ ``` public LRSSettingsPage(final IConfigPage configPage) { super("LRSSettingsPage.lrsTitle", configPage, null); } ``` } [/code] and the following properties files stored in maven’s default resources folder: LRS.properties `nav.header=LRS Management nav.settings.title=Settings ` LRSSettingsPage.properties ```auto lrsTitle=My LRS Title ``` I am able to compile and build and package the module just fine however it seems the properties files are not being discovered properly. When I install the module the menu tab has question marks around it and displays the wrong string. Also, when attempting to open the config page the following error happens: [code]org.apache.wicket.WicketRuntimeException: Exception in rendering component: [Component id = main-title] at

LRS.properties needs to be loaded and unloaded by BundleUtil in your module’s GatewayHook. LRSSettingsPage.properties does not need to be manually loaded, but you have to place it in a package structure that mirrors the one that the LRSSettingsPage class is in, so something like src/main/resources/com/foo/bar/LRSSettingsPage.properties ---

Thanks for your reply. Adding and removing the bundle seems to have made a slight improvement in the appearance of the menu tab title. However, I still get the same error when attempting to open the page. My files are now organized in the following folders class files: …\lrs\lrs-gateway\src\main\java\lrs properties files: …\lrs\lrs-gateway\src\main\resources\lrs Interestingly enough, two strings are stored in the LRS.properties file, yet only one is discovered. Gatewayhook code added: [code] public void setup(GatewayContext gatewayContext) { BundleUtil.get().addBundle(“LRS”, getClass(), “LRS”); ``` } ``` public void shutdown() { ``` BundleUtil.get().removeBundle("LRS"); } ``` [/code] ---

I was mistaken about the settings page properties file - those keys should just be in the main LRS.properties file. It’s settings _records_ that are automatically loaded and must have a mirrored package structure (things that extend PersistentRecord). If your bundle is being loaded correctly you should be able to reference the keys/values by at the path “LRS.path.to.key”, so: LRS.nav.header LRS.settings.title LRS.lrsTitle ---

It works beautifully now, thanks!
