[jira] Commented: (TAP5-757) Allow PageLink's "page" parameter to accept page instance or class instead of just logical name to add new type-safe way of render request generation

["Vjeran Marcinko (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12723574#action_12723574 ] 

Vjeran Marcinko commented on TAP5-757:
--------------------------------------

Yes, good idea. Page class instance parameter would be especially useful when there is no activation context, so instead of:

@InjectPage
private EditUserPage editUserPage;

public EditUserPage getEditUserPage {
   return editUserPage;
}

one can write shorter :

public Class getEditUserPage {
   return EditUserPage.class;
}

> It's a bit overkill to use ActionLink only for render requests (when no action is needed) just to use its ability to return target page instance from handler methods, preconfigured with required context values. This type safety comes at the expense of 2 HTTP requests.
> If PageLink's "page" parameter could not only accept logical page name, but also page instance, then it would be possible to achieve same type-safety with only one HTTP request.
