List in Data Contract not decoding properly.

Posted on by DSAnderson 15

When passing Json data to a custom service with data contract

[DataContract]
public final class ProductionOrderPickingListContract extends ProductionOrderJournalContractBase
{
     private List pickingListLines;


     [
           DataMember('pickingListLines'),
           SysOperationLabel("@ManufacturingExecutionCommon:PickingListLines"),
           DataCollection(Types::Class, classStr(ProductionOrderPickingListLineContract)),
           Hookable(false)
     ]

}

the contract object does not properly decode the child List objects as seen below:

The JSON being passed is below:

    Hi DSAnderson,

    From the code you've shared so far, there seems to be not any problems, have you debugged it? You must specify the AifCollectionTypeAttribute attribute if you use an X++ collection as a parameter to or as a return value from a service operation. Then you can loop through the list values using ListEnumerator.

    I did decode it and the information does get imported but appears to be imported as a list of JSON strings instead of as a List of objects.  I can even iterate through the List of strings.

    My understanding of the information from the debugger is that you're getting JObject instances, not strings.

    Note that you can look at the actual types, while we're limited to the single screenshot you showed us.

    Apologies, you are correct that it is a Jobject - I was expecting it to be a List of objects.  Where I actually run into an issue is when I am iterating through the list.  The enumerator.current() returns a JObject without parameters and methods.  

           ListEnumerator enumerator = pickingListLines.getEnumerator();

           while (enumerator.moveNext())

           {

               ProdJournalBOM prodJournalBom = enumerator.current().parmProdJournalBom(prodTable, journalData);

               this.validate(prodJournalBom, allowValidationFailure);

               prodJournalBom.insert();

           }
