I'm try to show a list of components with AJAX zones in a table:
An 'ExecutableRowPair' consists of a header row (that's always visible) and
a details row, that's loaded through AJAX. The request is triggered by an
event link in the header row.
In ExecutablePair.java, I'm injecting the component as follows:
When rendering the AJAX response, Tapestry tries to evaluate an expression
on 'child' (*), but 'child' is null.
Why does Tapestry need the value of 'child'? How is it supposed to know?
