How can I use multiple DAC fields in a PXProcessingJoin result?

I have a custom processing screen with its data view (using a PXProcessingJoin) selecting from / joining multiple DACs. Here's an example:

public PXProcessingJoin<GLHistoryByPeriod,
                            InnerJoin<Account,
                                On<GLHistoryByPeriod.accountID, Equal<Account.accountID>>,
                            InnerJoin<Sub,
                                On<GLHistoryByPeriod.subID, Equal<Sub.subID>>,
                            InnerJoin<Branch,
                                On<GLHistoryByPeriod.branchID, Equal<Branch.branchID>>,
                            LeftJoin<GLHistory, On<GLHistoryByPeriod.ledgerID, Equal<GLHistory.ledgerID>,
                                                And<GLHistoryByPeriod.accountID, Equal<GLHistory.accountID>,
                                                And<GLHistoryByPeriod.subID, Equal<GLHistory.subID>,
                                                And<GLHistoryByPeriod.finPeriodID, Equal<GLHistory.finPeriodID>,
                                                And<GLHistoryByPeriod.branchID, Equal<GLHistory.branchID>>>>>>,
                            InnerJoin<MasterFinPeriod, On<GLHistoryByPeriod.finPeriodID, Equal<MasterFinPeriod.finPeriodID>>>>>>>,
                            Where<GLHistoryByPeriod.finPeriodID, Equal<Constants.finPeriod>,
                                And<GLHistory.finYtdBalance, Equal<Constants.finYTDBalance>>>> FileData;

and here's the constructor:

public BlackLineFileMaint()
{
    FileData.SetProcessCaption("Process");
    FileData.SetProcessVisible(true);
    FileData.SetProcessAllCaption("Process All");
    FileData.SetProcessAllVisible(true);
    FileData.SetSelected<BlackLineFileData.selected>();
    FileData.SetProcessDelegate(GenerateFiles);
}

The problem I have is, in the process delegate (here called 'GenerateFiles'):

public static void GenerateFiles(List<GLHistoryByPeriod> records)
{
     //...code goes here - but I need more than the GLHistoryByPeriod fields..
}

How can I get the values of any of / all the other DAC fields in the PXProcessingJoin select? Is there some other way of creating the delegate that adds the other DACs?

Thanks much..

Solution

You can pass the entire resultset to your delegate. Sorry, I didn't use your view, but I think you can use this as a template:

public class TestProcessing : PXGraph<TestProcessing>, IGraphWithInitialization
{
    public SelectFrom<SOOrder>
        .InnerJoin<Customer>.On<SOOrder.customerID.IsEqual<Customer.bAccountID>>
        .ProcessingView ProcessingView;

    // It is called when you press the process button
    public void Initialize()
    {
        // Filter by selected records
        var dataFromView = ProcessingView.Select()
            .Where(it => it.GetItem<SOOrder>().Selected == true)
            .ToList();
    
        ProcessingView.SetProcessDelegate(list => DoProcess(list, dataFromView));
    }

    protected static void DoProcess(List<SOOrder> list, List<PXResult<SOOrder>> dataFromView)
    {
        foreach (var data in dataFromView)
        {
            var soOrder = data.GetItem<SOOrder>();
            var soLine = data.GetItem<Customer>();
        }    
    }
}
