Reporting Example?

I've tried to work with the reporting extension, but it didn't work. I just retrieved some data from a rm-repository, connected it to a report-operator and connected the latter to a "generate report"-operator. Here's the process definition:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.0">
  <operator activated="true" class="process" expanded="true" name="Process">
    <process expanded="true" height="692" width="961">

        <parameter key="repository_entry" value="wellfields"/>
      <operator activated="true" class="reporting:report" expanded="true" height="60" name="Report" width="90" x="246" y="390">

        <parameter key="report_item_header" value="test-header"/>
        <parameter key="specified" value="true"/>
        <parameter key="reportable_type" value="Data Table"/>

          <parameter key="block_type" value="attribute_block"/>
          <parameter key="use_block_type_exception" value="false"/>

          <parameter key="show_name" value="true"/>

          <parameter key="show_range" value="true"/>
          <parameter key="show_sum" value="true"/>
          <parameter key="show_missings" value="true"/>
      <operator activated="true" class="reporting:generate_report" expanded="true" height="76" name="Generate Report" width="90" x="380" y="390">
        <parameter key="report_name" value="test"/>
        <parameter key="format" value="PDF"/>
        <parameter key="pdf_output_file" value="test.pdf"/>
        <parameter key="pdf_template_file" value="/Users/brandl/tdst.pdf"/>
        <parameter key="image_template_file" value="no file selected"/>
        <parameter key="section_one_font" value="courier"/>
        <parameter key="section_two_font" value="courier"/>
        <parameter key="section_three_font" value="courier"/>
        <parameter key="section_four_font" value="courier"/>
        <parameter key="section_five_font" value="courier"/>
        <parameter key="text_content_font" value="courier"/>
      <connect from_op="Retrieve" from_port="output" to_op="Report" to_port="reportable in"/>
      <connect from_op="Report" from_port="reportable out" to_op="Generate Report" to_port="through 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
However, when I run this basic process, I get the following error:
"No report was specified for this reporting operator."

What is wrong with my setup?

Best, Holger

    before one can add something to the report using the Report operator, you have to open a report using the Generate Report operator.
    The name's really misleading, don't know why we have overseen it when we renamed the others.
    Sorry for the inconvenience.

    Thanks for your answer.

    Does this mean, that I have to connect all the examplesets which I would like to include into a report to the "Generate report" operator? How are inputs to it associated to "Report"-operators (which I assume to be connected to the outputs of the "Generate Report"-op)?

    It seems ways more natural to me to connect data-sets to report-operators, which are consumed by a "generate report" node (which doesn't need any outgoing connections).

    Where can I find any examples/documentation? Are the reporting operators already used in production, or are they still under development?

    the reporting operators have been part of the Enterprise Edition for over a year now. That's the main reason, why we didn't change the behavior to be more 5.0 like: We couldn't break with compatibility for people paying us.
    And no, the Report Generator just opens a Stream that's accessed by the subsequent Report operators via its name. To report things, you simply have to open a report using the Generator and add parts by the Report operator.

    Unfortunately there are no samples right now.
