running nightly MATSim-Build: a3bd8cf

I get an error and the log looks like this:

 There is no activity type that has an opening *and* closing time (or opening time and late penalty) defined.
 This usually means that the activity chains can be shifted by an arbitrary
 number of hours without having an effect on the score of the plans, and thus
 resulting in wrong results / traffic patterns.
 If you are using MATSim without time adaptation, you can ignore this warning.

As I have no clue, what about the config might be wrong, where do I start with this information?

Can anybody help?

thanks

Although I still have no idea, why this error occurred,

the safest bet for getting a working configuration seems to be

1. generate a default config from your MATSim version
2. change everything you need with some kind of diff-editor
3. stepwise
4. check if it still works...

at least this way I got my scenario to simulate.

Re: NullPointerException - unspecified problem with config consistency

The failing line in the code is

if (c.planCalcScore().getModes().get(TransportMode.pt).getMarginalUtilityOfTraveling() > 0) {

Presumably, the mode parameters for TransportMode.pt did not exist in your configuration (as constructed by the code), and then this throws a null pointer exception.

Presumably, this happens rarely with other people, since those parameters are set to some value by default, so you must have picked a configuration that erases them.

Still, looks like a bug to me.  I added code that hedges against these things being null (which is an allowed state).

Overall, I still recommend minimalistic config files, i.e. only copy those lines from the default config that you want to change.  Otherwise, you will run into additional problems with MATSim version updates.
