Hi
You can do what you want creating a custom ViewHandler and overriding
createView(...) method like this:
@Override
public UIViewRoot createView(FacesContext context, String viewId)
{
UIViewRoot root = super.createView(context, viewId);
if (root != null)
{
FlowHandler flowHandler =
context.getApplication().getFlowHandler();
if (flowHandler.isActive(context, "", "flow1") &&
!viewId.startsWith("/flow1/"))
{
Flow flow = flowHandler.getFlow(context, "", "flow1");
flowHandler.transition(context, flow, null, null, viewId);
}
}
return root;
}
The code just check when the flow is active and if the view belongs to the
flow. If the navigation goes out of the flow it send a trasition ending the
flow.
Really this topic is being discussed under the EG, see:
https://java.net/jira/browse/JAVASERVERFACES_SPEC_PUBLIC-1253
Let's see what happen.
