AbstractColumn: how to set propertyName to get value from HashMap?

[iezzomaniero]

Hi, i'm trying to set the propertyName of an AbstractColumn to get a value from a HashMap with the key using round brackets but it's not working. I don't get any errors but the value is not printed in the report. What am I doing wrong?

ColumnBuilder.getNew().setColumnProperty("projectsHours(1)", Double.class.getName()).setTitle("Project " + index).setWidth(60).build());

Thanks -Iezzo
