RapidMiner 7.2 to 7.3 sentiment analysis issue

hi...what are you using for the sentiment analysis?  The Aylien Sentiment extension operator?

I just tested it with the Aylien operator and it all seems to be working fine.

        <parameter key="query" value="foo"/>
        <parameter key="limit" value="2"/>
      </operator>

      </operator>
      <connect from_op="Search Twitter" from_port="output" to_op="Analyze Sentiment" to_port="Example Set"/>
      <connect from_op="Analyze Sentiment" 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>

If you upgraded to RapidMiner Studio v7.3, make sure to update all your extensions to the latest version. We've made some security enhancements that might cause older extensions to not work right.
