> 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}
> This is causing by the line 174 in org.drools.decisiontable.parser.xls.ExcelParser :
> {code:java}
> if ( num - Math.round( num ) != 0 )
> {code}
> The end users should have the possibility to keep the same formatter for the same column, with integers or not.
