[rules-dev] Open a BRL file from BRMS in Eclipse throws an Exception

Wed Sep 23 01:48:42 EDT 2009

Hi Michael.

There is a nature tag in my brl-XML:

  <rhs>
    <assert>
      <fieldValues>
        <fieldValue>
          <field>reason</field>
          <value>Too Young</value>
          <nature>1</nature>
          <type>String</type>
        </fieldValue>
      </fieldValues>
      <factType>Rejection</factType>
      <isBound>false</isBound>
    </assert>
  </rhs>
</rule>

I try to check with the pure plugin from Drools later on, I tried with
Eclipse and the latest JBoss Tools as well, no difference...

Cheers
Bernd

Also - if you open up the BRL as text - so you see a <nature> type tag
or something that could be causing that?
