Well, your component will have a field with a parameter:
public class SomeComponent {
@Parameter
private int rowsPerPage;
}
If you modify the class to expose that value by adding:
public int getRowsPerPage() { return rowsPerPage; }
Or by adding @Property annotation to the rowsPerPage field.
Your now on the right track.
You can inject the component instance into the containing page (or component):
public class MyPage {
@Property @InjectComponent
private SomeComponent zulu;
}
And in your MyPage.tml, reference the component's property and inside
it, rowsPerPage:
<t:somecomponent t:id="zulu" rowsPerPage="17"> .... The component
has ${zulu.rowsPerPage} rows per page.
In other words, if your component wants to make that information
visible, it can do so. There's a bunch of variations on this, of
course. As you get more experienced with OO development and Tapestry,
you'll see a lot of ways to take advantage of the fact that
information is organized into objects and properties.
