1:08 a.m.
I am trying to start a new nested conversation using
| <s:link view="/a.xhtml" propagation="nest" value="Go to
A"/>
|
but I am getting an exception (see below). But the exception disappears if I start a
nested conversation in an action method. So, it'll work if I re-write with the
following:
| <s:link view="/a.xhtml" action="#{actionClass.prepare}"
value="Go to A"/>
|
| @Name("actionClass")
| public class ActionClass {
|
| @Begin(nested = true)
| public void prepare() {}
|
| }
|
I am using Seam 1.1GA. Also assume that a long running conversation already exists at the
time of invocation. Does anyone know why this is happening? Here's the exception:
