ListIterator is null, but why?

Hello,

I tried to execute code from the Implementing the Account and Financial Dimensions Framework (White paper), page 34. But for some mysterious reason it's not working.

DimensionValueService service = new DimensionValueService();
DimensionContract dimensionContract = new DimensionContract();
DimensionValueContract dimensionValueContract;
DimensionValue dimensionValue;
List dimensionValueContractList;
ListIterator contractorIterator;

;


dimensionContract.parmDimensionName(#DimName);
dimensionValueContractList = service.getDimensionValues(dimensionContract);
contractorIterator = new ListIterator(dimensionValueContractList);

while(contractorIterator.more())
{

dimensionValueContract = contractorIterator.value();
dimensionValue = dimensionValueContract.parmValue();
contractorIterator.next();
{info(strFmt("%1", dimensionValue));}

}

contractorIterator is always null! And the dimensionValueContractList is initialized and has values in it.
I tried to create simple list and iterator in the same way to test it and eveything works fine.

I'm really confused, I'm missing somehting very simple.

Please help,
Thanks in advance.

Maybe the list is on a different tier (client/server) than the enumerator. If it's the case and you use the recommended way, enumerator instead of iterator, it will work, but it would still be more efficient to do it on the same tier.

You were right.

I tested Enumerator in the job and it works perfectly fine.

contractorEnumerator = dimensionValueContractList.getEnumerator(); while(contractorEnumerator.moveNext()) { dimensionValueContract = contractorEnumerator.current(); dimensionValue = dimensionValueContract.parmValue(); {info(strFmt("%1", dimensionValue));} }

But in my class I still use Iterator, but from now executing of class is on server side.
Thank you.

I setup testing of an RDP report like this post where I create a Job, create the data contract and RDP objects before calling processReport() on the RDP object.

However, one of the data contract parm methods was for a multi-select parameter that handled a List object.

In the processReport() method I can see the List object having a value but then I create a ListIterator passing it the List and thereafter the ListIterator is null.

Is the calling Job running on a different tier to the RDP object and causing this problem?

You wouldn't ever get into this problem in the real execution, when the RDP class would be called by a report.

The problem is your test code, when you're creating the data contract object in a job, i.e. on client.
