Access public variables in extension class using chain of command

When you wrap a method, you can also access public and protected methods
and variables of the base class.
CustInvoiceJour is a base class variable hence you will be able to access it. Eg.

[ExtensionOf(classStr(SalesConfirmJournalCreate))]
Final class SalesConfirmJournalCreate_Extension
{
protected void createJournalHeader()
{
next createJournalHeader();
//It's as simple as this:
custConfirmJour.SalesBalance = 0;
}
if gets an error, It's an old bug with variable names. Declare new one and use it:
protected void createJournalHeader()
{
next createJournalHeader();
CustConfirmJour custConfirmJourLocal =
custConfirmJour;
custConfirmJourLocal.MyField = 'blah-blah';
}
}

How to refresh form datasource from Class or Table in D365fo

// If this is a data source on a form, then refresh from table in AX7 / D365.
if (FormDataUtil::isFormDataSource(this))
{
	FormDataUtil::getFormDataSource(this).refresh();
}


Refresh from data source from class in AX7 / D365
Table tableBuffer;
FormDataSource formDataSource;
tableBuffer = _args.record();
formDataSource = FormDataUtil::getFormDataSource(tableBuffer);
formDataSource.research();

Refresh from data source from class in AX7 / D365 from workflow
I just wrote couple of custom workflow. But on Submit workflow, form did not refresh and available for edit until, you manually refresh the form. That behavior is certainly not acceptable by end user.

usually “_args.caller().updateWorkflowControls();” will do this. Possible I missed something. But for its solution I add following code snippet for data set refresh that works for me.

dssRfpTable tableBuffer = _args.record();
FormDataSource custInvoiceTableDataSource;
custInvoiceTableDataSource = FormDataUtil::getFormDataSource(tableBuffer);

 

if (custInvoiceTableDataSource)
{
custInvoiceTableDataSource.research(true);
custInvoiceTableDataSource.refresh();
}

How to open new form through code in AX

 /// <param name = "_sender">The AnswersButton control.</param>
    private void onAnswersButtonClicked(FormFunctionButtonControl _sender)
    {
        FormRun formRun = _sender.formRun();
        CaseDetail caseDetailBase_CaseDetail = formRun.dataSource(formDataSourceStr(CaseDetail, CaseDetailBase_CaseDetail)).cursor() as CaseDetail;
        Args answersButtonArgs = new Args();
        answersButtonArgs.caller(_sender);
        answersButtonArgs.record(KMVirtualNetworkAnswerTable::find(CaseDetailBase_CaseDetail.AnswerId));

        new MenuFunction(menuItemDisplayStr(KMKnowledgeCollectorResultAnswer), MenuItemType::Display).run(answersButtonArgs);
    }
