Hello guys and gals.

I have a question about usage of p:parameters.

Is it possible to use the p:parameters in a p:variable?


<p:parameters name="params">
    <p:input port="parameters">
      <p:pipe step="run-pipe" port="par"/>
    </p:input>
  </p:parameters>

  <p:variable name="pipeline"
select="/c:param-set/c:param[@name='pipeline']/@value">
    <p:pipe step="params" port="result"/>
  </p:variable>

This causes this error.

SEVERE: it is a static error for a variable's document connection to
refer to the output port of any step in the surrounding container's
contained steps


but if I wrap the p:variable in a p:group, with the usages of that
variable, then it works.

Is there any other way of extracting a parameter from the p:parameters
pipe?


Thanks.
