How to clear the body of an injected component

[Ed Cohen <ec...@powersteeringsoftware.com>]

I have a component that is rendered in java code.  The main part has a
loop that renders a DirectLink on each iteration.

 

I obtain the DirectLink by injection, and want to set its body and then
render it.  I tried getting the DirectLink, then calling addBody to set
its body, and then rendering.  What I found was that the same DirectLink
component was being returned because its body was the accumulated body
from all previous iterations of my loop.  It was kind of cool looking
but wrong.

 

Is there a way to clear the body, or alternatively, to get a different
DirectLink each time?

 

Thanks in advance.

Remember:  In Tapestry, its a static structure and a dynamic behavior.

I think what you want to do is render an <a> tag that generates a URL
using the direct service.  You can do this in Java code (by injecting
the DirectService).  Make your component implement IDirect.
