Hello,
I have an idea for PageLink version that would be type-safe because I simply
love when I don't have to worry about page names or context parameters in my
templates as much as possible, especially cosidering that I like to refactor
much...
If PageLink could accept page *instance* as parameter, it could resolve page
name and also activation context from this instance.
For example, in ViewAllEmployeesPage class I need to provide
EditEmployeePage instance for each looped employee ID as activation context,
I could have:
private Employee employee; // looped employee
@InjectPage
private EditEmployeePage editEmployeePage;
public Object getEditEmployeePageInstance() {
editEmployeePage.onActivate(employee.getId()); // configuring page
isntance
return editEmployeePage;
}
It seemed simple enough to write my own TypeSafePageLink that would render
these links via :
PageRenderLinkSource.createPageRenderLinkWithContext(Class pageClass,
Object... context);
...but I got in problem how to extract this activation context parameter
from page instance parameter ?
Any Tapestry utility method for this somewhere?
Actually, documentation of current PageLink states that:
".If no context is supplied, then the target page itself will supply the
context via a passivate event."
I'm little confused how can PageLink resolve activation context from target
page specified with only its name, when one would actually need an
*instance* of configured page to extract its activation context via
"passivate" event? Or I have mixed up some things here?
Regards,
Vjeran
