Creating a simple sysFramework batch with a query as parameters

I am trying to create a sysFramework batch which creates a purchaseOrder based on a tender.

For this I am trying to add a query to my batch operation. I tried using KanbanPrinterBatch as an example, but I cannot choose any parameters.

My contract class:

[DataContractAttribute]
class CreatePurchaseOrdersForTendersContract
{
str packedQuery;

public Query getQuery()
{
return new Query(SysOperationHelper::base64Decode(packedQuery));
}

[
DataMemberAttribute,
AifQueryTypeAttribute('_packedQuery', queryStr(BWI_TenderPurchaseOrders))
]
public str parmPackedQuery(str _packedQuery = packedQuery)
{
packedQuery = _packedQuery;
return packedQuery;
}

public void setQuery(Query _query)
{
packedQuery = SysOperationHelper::base64Encode(_query.pack());
}

}

My controller:

class CreatePurchaseOrdersForTendersController extends SysOperationServiceController
{

public static void main(Args _args)
{
CreatePurchaseOrdersForTendersController::newStandard(_args).startOperation();
}

public static SysOperationController newStandard(Args _args)
{
SysOperationController controller = new CreatePurchaseOrdersForTendersController(classStr(CreatePurchaseOrdersForTendersService));
controller.parmArgs(_args);
controller.parmDialogCaption("Create purchase orders for tenders");
return controller;
}

}

My service class only contains a simple process() method at this moment. The problem however, when I click on my menu-item and the sidepanel of the batch opens, the header called 'Records to include' somehow does not render at all.

Question 1:

I assume I'm missing just one simple thing or so, but I am not getting any errors anywhere. Does anyone know what I am missing?

I read somewhere you can use initQuery to change the query setup and it then has to be called in the controller class. I can see that the Kanban contract class does have an initialize method, but I do not see that getting called.

Question 2:

If I wanted to make some changes to my query via an init method, am I supposed to call it then or how is this initialize method of the kanban contract called when I can't find any references?
