What you need is a 'redirectAndWait'. This is something that IMHO is missing
in the current flow API, but very easy to implement. I don't have the cocoon
source here at the moment, but take a look at the 'sendPageAndWait' method in
the flow implementation you are using (probably javascript). This method
should call 'sendPage' and some other stuff. The 'redirectAndWait' method you
need will contain a 'redirect' (or is it 'redirectTo'?) and this other stuff.
That's all you need.
A custom flow engine I'm working on as an example:
public void sendPageAndWait(String uri, Object bizdata) {
sendPage(uri, bizdata);
getCont().endExecution(null);
}
public void redirectAndWait(String uri) {
redirectTo(uri);
getCont().endExecution(null);
}
Good luck,
Emond
