I've found the missing part myself: In case of no model for TransparentMarkupContainer itself it calls through to it's parents using Component.initModel to give those the chance to provide a model. The nasty thing here is that a simple default model of a parent is not enough, only models implementing the special interface IComponentInheritedModel are accepted and this behavior doesn't seem to be clearly enough documented to me. My default model was a simple Map and obviously didn't implement it so it was not taken into account. And because the fun never stops, it seems that wicket:message as an attribute is resolved using another class WicketMessageTagHandler which implements a different behavior regarding variable substitution which seems to result in a call to Component.getString without any model at all: > final String value; > if (tag.getAttributes().containsKey(attr)) > { > value = component.getString(key, null, > tag.getAttributes().getString(attr)); > } > else > { > value = component.getString(key); > } From my point of view both calls should provide the same model as MessageContainer does, because in both cases the component is a TransparentWebMarkupContainer with my custom panel as parent, which is able to provide a default model. I don't see why there should be a different approach than in MessageContainer. Additionally it seems there's a misplaced comment in Localizer.getString: > // If a property value has been found, or a default value was given, > // than replace the placeholder and we are done > if (value != null) > { > return value; > } There's no replacement done and the one mentioned seems to happen in getStringIgnoreSettings already. So half the way done and still no solution...
