Re: Non-primary port connection between non-contiguous steps

Yves,

You're confusing the declaration of the steps and it's use

You first declare the step without giving any connection to other steps

And then you do you connection with

<srz:step1 name="exec_step_1"/>
<srz:step2 name="exec_step_2"/>
<srz:step3 name="exec_step_3">
  <p:input port="result_from_step1">
    <p:pipe port="result" step="exec_step_1"/>
  </p:input>
 </srz:step3>

Hope this helps
