             Summary: NestedStringResourceLoader ignores hard-coded default values and throws MissingResourceException
                 Key: WICKET-6393
                 URL: https://issues.apache.org/jira/browse/WICKET-6393
             Project: Wicket
          Issue Type: Bug
          Components: wicket
    Affects Versions: 7.7.0
            Reporter: Richard Eckart de Castilho


The NestedStringResourceLoader ignores hard-coded default values and throws a MissingResourceException.

Consider FormComponen.getString()

{noformat}
		private String getString(Localizer localizer, String key, Component component)
		{
			triedKeys.add(key);

			// Note: It is important that the default value of "" is
			// provided to getString() not to throw a MissingResourceException or to
			// return a default string like "[Warning: String ..."
			return localizer.getString(key, component, "");
		}
{noformat}

The default value provided here actually gets lost in the call hierarchy in `Localizer.getString()` (line 232). That seems to be ok because the code there seems to expect that any code it calls will not take into account the `ThrowExceptionOnMissingResource` setting (at least that is what I infer from the method name `getStringIgnoreSettings`. However, again further down the hierarchy, `NestedStringResourceLoader.handleMissingKey()` (line 166) is called which throws a MissingResourceException and defies the default-value handling code in `Localizer.getString()`.

Here is a stack trace:
