Thread: [Repast-interest] Cannot construct repast.simphony.engine.schedule.ScheduleParameters as it does no

Hi,

Every time I add a display to my model, upon running the model the warning below occurs. Anyone any idea why this happens?

Regards

Can you send me the display xml file, and the scenario.xml file? They will be in your scenario rs directory. The display file will look something like:

repast.simphony.action.display_3.xml

although the number there may be different.

Hi Nick,

Thank you. You are correct. I am using java 7 and switching back to Java 6 does solve the issue. Replacing xstream-1.3 with its latest stable version causes all sorts of other issues, unless I am doing something wrong here. So it look like I will not be able to use java 7, unfortunately.
