Hi,
I'm trying to obtain a page from it's name to set a property on it. I'm
trying something like this:
Component page = componentSource.getPage("MyPage");
MyPage myPage = (MyPage)page;
myPage.setSomething("");
This code fails in the cast, despite a
System.out.println(page.getClass().getName());
prints the expected page class (com.myapp.pages.MyPage).... I assume is
because all the instrumentation T5 does to the pages, but is there a way to
obtain a page from its name and then set a property that the "original"
class has??
The only workaround i've found is to call the method setSomething with
reflection, without casting it to MyPage, but it would be really nice not to
use reflection for this....
Regards.
