Exception in Gosu script editor: Cannot traverse in window mode

[Mirza Daniyal Ahmad]

I am fairly new to Gosu scripting and am getting this below exception on in Gosu script editor while trying to print an entity:

var period = Query.make(entity.PolicyPeriod).compare("PublicID", Equals, "somePublicID").select().FirstResult
print(period)

if(period.Buildings_CG == null) ///**********************This line is failing *******************//
{
  print("period.Buildings_CG is null ?")
}

Exception:

java.lang.IllegalArgumentException: Cannot traverse in window mode

Any idea what may be wrong here?

PolicyPeriod comes in two modes - Window mode and Slice mode.

var period = Query.make(entity.PolicyPeriod).compare("PublicID", Equals, "somePublicID").select().FirstResult

period = period.getSlice(period.EditEffectiveDate)

if(period.Buildings_CG == null) ///**********************This line is failing *******************//
{
  print("period.Buildings_CG is null ?")
}

This is a feature of Guidewire where data can be changed as of some effective date. This means that there can be multiple versions of the job. When you try to look into the Period most of the times it will be in a Slice mode. You can also view data across all the versions and this is called Window mode. The above Query gave you a object in Window mode and you need to look at the building's properties that are available as of some date(this will be a Slice).

Hi,

Curious but what if EditEffectiveDate is the overall value you are using to access the PolicyPeriod and you really don't need the slice?

Hi Paul,

For your question here is the detailed answer.

This can happen at multiple points in the Guidewire application. It has been seen in both configuration and integration code. All objects in PolicyCenter can either be in slice or window mode. 

Slice - Contains the version of the object at a specific point in time, such as the effective date of the job. This is the mode that most people interact with.

Window - Contains the data for all the versions of the object for the life of the policy term.

There are many functions in the system that assumes we are running in slice mode. Each of these functions will throw the Illegal Argument Exception. To fix this, we need to find the PolicyPeriod. This may be in the current method or we may need to look in calling functions or traverse the entity model. We can then use the getSlice(date) method to get the slice that is effective on a specific date. In most cases, we will use the effective date for the current job.

Hope it clarifies for your question.

Thanks,

Sridhar Chinchili
