Yes this is a public field. In this case the error will much be something like an IllegalAccessException. It's like there is a type problem. The strange thing is that this line is not working: if(directWriteField) src = "target." + field + " = " + " $1;"; but this one is: if(directWriteField) src = "target." + field + " = new java.util.Date();"; View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4223016#...
