I am also trying to have restful URLs for my facebook application.
I have tried to follow the instruction here, but I got to a dead end. Here
is my declaration inside MyApp.java.init():
QueryStringUrlCodingStrategy page1URLS = new
QueryStringUrlCodingStrategy(
"page1",
Page1.class
);
mount(page1URLS);
QueryStringUrlCodingStrategy page2URLS = new
QueryStringUrlCodingStrategy(
"http://apps.facebook.com/myapp/page2";,
Page2.class
);
mount(page1URL2);
my application is run in an IFrame in facebook. when I use a
BookmarkablePageLink to link to page1 and page2, I get the following urls:
page1: http://localhost:8080/some-directory/page1?some_param=29
page2: http://apps.facebook.com/bennyworkbook/page2?some_param=2
clicking page1 link works perfectly. however, If the link is bookmarked or
saved by the user, and accessed later, the application is loaded outside the
facebook realm. I would like the links to all point to facebook, so
bookmarking them would link to my application's page ON FACEBOOK.
page2 link looks perfect, because it links to facebook. However, it doesn't
work. I get a 4040 with the following error:
"The requested resource (/page2) is not available."
any ideas how I can have all the links look like page2 link but work good
(link page1 link)?
thanks,
Benny.
