This has already been reported by other users. This is a bug in the
engine, and I have already fixed it for the next release. I don't think
there is a way to workaround the issue with the present version.

Fixed for the next release. BTW, the following is not correct in your

<p:input port="source">

Unless you make the "source" port accept sequences (sequence="true"),
you will get a dynamic error.

Thanks for reporting the problems.
