[T5] programmatically setting/getting @Property values

[manuel aldana]

hi,

@Property is used, so setters/getters are generated in runtime. As an
example take PageLink, it is usually set through .tml file (with
t:page="xxx"). How is it possible to set @Property fields
programmatically in a consise and short way?

Or is it always better to use .tml templates for setting @Property fields?

As far as I know, it is not possible to programatically set or get
@Property fields, only access them from bindings (don't forget that using
a ${property} in a template is using the prop binding).
It is not a good practice to have templates changing the state of page
classes and components unless it is something like setting a Grid row or
index or a Loop value or index.

I think you are asking two different things.

You can use the PropertyConduit service to create PropertyConduit
instances; these allow you to dynamically read and update an
expression on any object; it doesn't even have to be a component.

So propertyConduitSource.create(foo.getClass(), "stuff").set(foo,
"mojo") will create a PC for the "stuff" property and update it.

To give you some background why I would like to use to set the PageLink
component programmatically:

In a navigation-component (which is built up dynamically) I want to
refer to a main-content page. For that I'd like reuse the PageLink
component, so I can use tapestry facilities for link creation. So far
the navigation-component worked without template, so don't want to
create a template for just passing a PageLink component.
