So instead of getting for example; 1. | package ido.droolsrules.dqsrulesqa; 2. | 3. | import java.lang.Number; 4. | 5. | rule "Test Camera Model" 6. | dialect "mvel" 7. | when 8. | cam1 : Camera( brand.toLowerCase() == "sony" ) 9. | then 10. | cam1.setLens( 5.0 ); 11. | end Rule is generated (In source tab) as: 1. | package ebay.droolsrules.dqsrulesqa; 2. | 3. | import java.lang.Number; 4. | 5. | rule "Test Camera Model" 6. | dialect "mvel" 7. | when 8. | cam1 : Camera( brand.toLowerCase("") == "sony" ) 9. | then 10. | cam1.setLens( 5.0 ); 11. | end view line 8 to spot difference.
