Hello,
Following a suggestion from a fellow T5 user (cheers Nicolas!) I've
changed my page name injecting strategy. I now have a
ComponentClassTransformWorker which adds a Mixin to every Page
component. This Page Mixin (in the afterRender() method) then injects
the page name as a comment in the Document model.
This has the benefit of injecting the name of the "rendered page" as
oppose to the name of the requested page. The important difference is
that on error pages (http 404 and 500) I now inject the names of the
error pages and not what the user originally asked for.
What I'd like to know now, is there a "nice" way, in the
ComponentClassTransformWorker to check if I'm transforming a page?
Both of the following work, but neither seem particularly pleasant:
@Inject
private ComponentClassResolver resolver;
try {
resolver.resolvePageClassNameToPageName(transformation.getClassName());
} catch (IllegalArgumentException e) {
// not a page... goodbye!
return;
}
... or...
if (!transformation.getClassName().contains(".pages."))
// not a page... goodbye!
return;
Any ideas?
Cheers,
Steve.
