Drools Exception - no alternative viable input

Anonymous — Sat, 16 Nov 2024 12:54:12 GMT

Hi All,
I'm having an exception when reading on rules from Talend, I tried deleting spaces, but still exception occurs.
The versions below:
Talend Version: 4.1.2.r53616
Guvnor Version: drools-5.1.1-guvnor

rule "test_123_rules_21"
when
FIELD_A=2009-04-25 AND FIELD_B=999-9999
then
FIELD_C=SB
end

: Line 3:0 no viable alternative at input 'FIELD_A' in rule "test_123_rules_21"
: Line 3:23 no viable alternative at input 'FIELD_B' in rule "test_123_rules_21"
Exception in component tRules_1
java.lang.IllegalArgumentException: Could not parse knowledge.

try it with guvnor 5.0.1. current tbrms component is not yet compatible with later version.
http://download.jboss.org/drools/release/5.0.1.26597.FINAL/drools-5.0-guvnor.zip
besides, "FIELD_A=2009-04-25" is equivalent to "FIELD_A=1980", you need to specify "literal value" while adding this field as condition.
