Hey,
Within a long running conversation I'm trying to start a nested one with

<s:link ...>
<s:conversationPropagation type="nested">
</s:link>

(I tried to use the propagation param with s:link but for some reason the generated link has no conversationPropagation parameter)

But I get a NPE
Here's the stack trace:

What's the cause of that?

I'm using Seam 2.0.3CR1

Thanks,
