RE: [EXTERNAL] - Re: custom search component process method not called

Sigh.  Best way to find a stupid mistake is post it.

I had this...
<requestHandler name="/select" class="solr.SearchHandler">
    <!-- default values for query parameters can be specified, these
         will be overridden by parameters in the request
      -->
    <lst name="defaults">
      <str name="echoParams">explicit</str>
      <int name="rows">10</int>
        <arr name="last-components">
	<str>saveStateComponent</str>
      </arr>
  </lst>
</requestHandler>

Instead of this....

<requestHandler name="/select" class="solr.SearchHandler">
    <!-- default values for query parameters can be specified, these
         will be overridden by parameters in the request
      -->
    <lst name="defaults">
      <str name="echoParams">explicit</str>
      <int name="rows">10</int>
    </lst>
    <arr name="last-components">
	<str>saveStateComponent</str>
    </arr>
</requestHandler

I believe the init bit is called on startup, so that leaves the second part of your puzzle. I find this a bit suspicious though:

   <str name="saveCore">${solr.core.name}</str>

Are you sure this is different for all three cores? My thought is that the component is being called for all three cores but it's hard to see b/c the name is the same.

Total guess though.
