"Process Documents from Web"

Bunc

I am a new user so please excuse if this is a simple problem!
I am having a problem with "process documents from web" operator.

As I understand it this operator is basically the same as Crawl Web operator but allows for an inner process to process crawled content before storing it.

I have the following very simple start for my process

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.0">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="5.0.0" expanded="true" name="Process">
    <process expanded="true" height="673" width="1094">
      <operator activated="true" class="web:process_web" compatibility="5.0.3" expanded="true" height="60" name="Process Documents from Web" width="90" x="179" y="120">
        <parameter key="url" value="http://www.aol.com"/>
        <list key="crawling_rules">
          <parameter key="follow_link_with_matching_text" value=".*"/>
          <parameter key="store_with_matching_content" value=".*"/>
        </list>
        <parameter key="add_pages_as_attribute" value="true"/>
        <parameter key="max_pages" value="10"/>
        <process expanded="true" height="385" width="432">
          <connect from_port="document" to_port="document 1"/>
          <portSpacing port="source_document" spacing="0"/>
          <portSpacing port="sink_document 1" spacing="0"/>
          <portSpacing port="sink_document 2" spacing="0"/>
        </process>
      </operator>
      <connect from_op="Process Documents from Web" from_port="example set" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

When I run this I get an error "Process failed for input string follow link with matching text." As a result I cant get past this step to build a fuller process.

I cant see what I have specified wrong - im sure its something simple. I dont have any inner operators specified tathe moment - I tried it with inner operators but that made no difference and the problem is clearly at the start of the process with the crawl and store rules

Update:
This may be related to my problems with the above possibly.

I was using the Crawl web operator and encountered the same problem after editing the crawl rules. The problem remained when I re-edited and inserted the previously working rule.
When I examined the XML i noted that in the version that reported an error the parameters are coded as follows;

<list key="crawling_rules">
          <parameter key="follow_link_with_matching_url" value=".*(blogspot.com\/2010)"/>
          <parameter key="1" value=".+"/>
        </list>

In the working version however the parematers were coded as follows;

<list key="crawling_rules">
          <parameter key="2" value=".*(blogspot.com\/2010)"/>
          <parameter key="1" value=".+"/>
        </list>

Notice the parameter key in non working version is given as "Follow_link_to_matching_url"
Whereas in the second working version the parameter key is "2".

I did not change these myself and the change could only have been introduced I assume as part of the handling of the edit of the parameter key value. Is this a bug in the program?

I notice that the parameter keys in my first post (about the process documents from web operator) are also given as text strings rather than numbers. I now wonder if manually changing these to numerical key values would sort the problem - must try this.
