retrieve outer component reference from inner component

[Henri Dupre <he...@gmail.com>]

In my page I have a
@Border component
and inside a @ImageSubmit that should update (with ajax) a component outside
@Border.
I did some searches here, the only method that was suggested is to pass
component references though parameters but this would be quite ugly because
there is quite a bit of complex nesting involved. What other methods could I
use?

Thanks

You could use IPage.getNestedComponent() by calling
getPage().getNestedComponent()
(http://tapestry.apache.org/tapestry4.1/apidocs/src-html/org/apache/tapestry/IPage.html#line.111)

Other than passing the component around as a parameter,  is there a
reason why you need the reference to it at all?   Could you not just
call ResponseBuilder.updateComponent(String componentId)  ?
