Cannot use decimal formatters for integers in an excel decision table --------------------------------------------------------------------- Key: DROOLS-450 URL: https://issues.jboss.org/browse/DROOLS-450 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 6.0.1.Final Reporter: Maxime Falaize Assignee: Michael Anstis Priority: Minor Fix For: 6.1.0.Beta2 Attachments: issue_example.png When I use decimal formatter in an excel action column for numbers that are in fact integers, I am getting this exception : {noformat} Exception in thread "main" java.lang.RuntimeException: Error while creating KieBase[Message [id=1, level=ERROR, path=com/sample/my_decision_table.xls, line=5, column=0 text=Rule Compilation error The method setParameter(double) in the type MyObject is not applicable for the arguments (int, int)]] at org.drools.compiler.kie.builder.impl.KieContainerImpl.getKieBase(KieContainerImpl.java:260) at org.drools.compiler.kie.builder.impl.KieContainerImpl.newKieSession(KieContainerImpl.java:400) at org.drools.compiler.kie.builder.impl.KieContainerImpl.newKieSession(KieContainerImpl.java:375) {noformat} Actually, the system uses the format number "1,00000" (with comma in french) instead of "1.00000" like it should use. This is causing by the line 174 in org.drools.decisiontable.parser.xls.ExcelParser : {code:java} if ( num - Math.round( num ) != 0 ) {code} I don't understand why we use the formatted value when this test is not passed. I think the end users should have the possibility to keep the same formatter for the same column, with integers or not.
