[rules-dev] Conversion Error in DRL file

[Wolfgang Laun]

I can reproduce the error and I'll create a JIRA.

There are several things I can suggest as a workaround.

(1) Try using global Double for the temperature limits.

(2) Better: Use a single Parameter fact with double fields for
temperatureElevee and temperatureCritique:

  rule "1- aTraiterUrgent"
       when
               Parameter( $te: temperatureElevee )
               $patient : PatientDto( eval(
$patient.getDoubleValue("temperature") > $te ) )

(2++) You might also provide a getter double getTemperature for PatientDto.

  rule "1- aTraiterUrgent"
       when
               Parameter( $te: temperatureElevee)
               $patient : PatientDto( termperature > $te )
