TAPESTRY-1908
Hello, I disagree with the closing of this defect, because it could happen that the object type is defined at runtime: - the Property type of object parameter can be an interface - the object parameter can be instanciated on activation regarding activation context Why just not figure the beanType from object.getClass() ?

Re: render nested component
Hi,
Take a look at the Tapestry Tree component to see how recursive rendering
can be done.

Re: TAPESTRY-1908
I suspect you are talking about https://issues.apache.org/jira/browse/TAPESTRY-1908 instead of https://issues.apache.org/jira/browse/TAP5-1908? The actively worked T5 issues are in the TAP5 namespace. The former is a *nine years* old issue with a sample code to get it to do what you want. Furthermore, the beanType can by all means determined at runtime, that's exactly how Tynamo's tapestry-model (http://www.tynamo.org/tapestry-model+guide/) works. Object.getClass() works only for the simplest cases. Quite often you want to specify an interface as the beanType for your model.

render nested component
I am creating a Menu component (for a ul tag) that needs to
programmatically generate the child links.
I already have a MenuItem component, but this is parameter bound to a
template, whereas now I need to programmatically drive the parameters.
I either need to be able to create the existing MenuItem objects somehow in
the Menu component and render them, or I simply write the links out in the
menu - however since my Menu component isn't extending AbstractLink (like
MenuItem) I can't use writeLink().
Any ideas what is the simplest approach to resolve this? Code below.
