Travel to Object with Travel Destination Force of SocialForeceSystem

Hi,

I want to move a Task Executer by Activity [Travel to Object] with SocialForceSystem navigator that has a force of Travel Destination. But when the Task Executer arrives at the object, the system shows an error (time: 14.100000 exception: Exception caught in Executive::processeventinlist().) and the navigation system does not work any more. I attached a file, please run the model. When the task executer arrives in a queue, the exception occurs. (travelforce-2410.fsm)

I found that the error does not occur when I use A-star force or Activity [Travel to Location] / [Load].

Thank you.

This is a bug. When the agent reaches the goal, it finishes its travel task, but doesn't complete the goal. So then the next update cycle, the travel task is NULL and throws an exception.

I'll add a case to the development list to fix this. Thanks.

Your workaround of using Travel to Loc to travel to the object's location rather than to the object itself is a good solution in the meantime.
