p:viewport masks subpipeline errors

[ndw]

From private email:

I think I found out what’s wrong: The match pattern performs fine but when an error is raised inside the <p:viewport>, the message is that the match pattern couldn’t be evaluated, not the actual error.

Try something like this:

<p:viewport match="/*/*">
      <p:variable name="xxx" select="error((), 'blah')"/>
      <p:identity/>
    </p:viewport>

Fixed in 1.1.16
