> Components: tapestry-core
> Affects Versions: 5.0.13
> Reporter: Fritz Pröbstle
> Assignee: Howard M. Lewis Ship
> Priority: Minor
>
> Abstract: Error message not correct
> Workaround: Specify t:id for the component
> Problem: Wrong error message confuses user
> Description:
> I have a Page Uebersicht with uses a Component "common/kopf" by specifiing
> only t:type="common/kopf" with *NO* t:id .

> -------------------------------
> In the Page-class I reference the "common/Kopf" by type , which works *BUT*
> generates the following error:
> [ERROR] Uebersicht Embedded component(s) kopf are defined within component
> class .....pages.Uebersicht, but are not present in the component template.
> ----------------
> public class Uebersicht {
>
>
> @Component ( type="common/kopf")
> private Kopf kopf;
> ...
> }
> ---------------
> The error generation is emitted by
> PageLoaderProcessor.loadTemplateForComponent ( see my comments inside the
> code below )
> ----------------
> for (String id : loadingComponentModel.getEmbeddedComponentIds())
> // getEmbeddedComponentIds returns {"kopf"}
>
> // -I expect it to return {"common/kopf" } for a
> component in the subpackage "common" of the "tapestry.app-package"
> embeddedIds.put(id, true);
> idAllocator.clear();
> for (String id : template.getComponentIds()) // getComponentIds
> returns *ONLY* ids which are explictly set by t:id- implicit id which are
> derived from t::type are missing
>
> // in this case I expect "common/kopf" inside the result
> {
> idAllocator.allocateId(id);
> embeddedIds.remove(id);
> }
> if (!embeddedIds.isEmpty())
>
> logger.error(ServicesMessages.embeddedComponentsNotInTemplate(embeddedIds.keySet(),
