What I missed in Acumatica processing page implementation - acumatica

Question

I try to create Acumatica processing page.
I have following aspx code:
<%# Page Language="C#" MasterPageFile="~/MasterPages/TabView.master" AutoEventWireup="true"
ValidateRequest="false" CodeFile="SM102000.aspx.cs"
Inherits="Page_SM102000" Title="Untitled Page" %>
<%# MasterType VirtualPath="~/MasterPages/TabView.master" %>
<asp:Content ID="cont1" ContentPlaceHolderID="phDS" runat="Server">
<px:PXDataSource ID="ds" runat="server" Visible="True" Width="100%"
PrimaryView="StackOverflowProcess" TypeName="StackOverflowSync.UsrStackOverflowProcess">
</px:PXDataSource>
</asp:Content>
<asp:Content ID="cont2" ContentPlaceHolderID="phF" runat="server">
<px:PXGrid ID="grid" runat="server"
Height="400px"

And following graph:
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using PX.Data;
using PX.SM;
using StackOverflowSync.DAC;
namespace StackOverflowSync
{
public class UsrStackOverflowProcess:PXGraph<UsrStackOverflowProcess>
{
[PXFilterable]
public PXProcessing<UsrStackOverflowSettingItem> StackOverflowProcess;
public PXCancel<UsrStackOverflowSettingItem> Cancel;
public UsrStackOverflowProcess()
{
StackOverflowProcess.SetProcessDelegate(Process);
}
public static void Process(List<UsrStackOverflowSettingItem> syncItems)
{
foreach (UsrStackOverflowSettingItem usrStackOverflowPrcSt in syncItems)
{
//
}
}
public override bool IsDirty => false;
}
}
If I compile and open all of it in my Acumatica instance I see three buttons: Process, and Process All and Cancel, which is expected behavior. When I check "Process All" then method Process receives all items. But if I select few items, and press at Process, method Process doesn't receive any ( I've checked in debugger ). What else should I add/remove to my code in order make button Process work properly?

Answer 1

Reported issue is caused by the non-nullable SettingID field. All DAC fields must be of a nullable type. Your custom screen should operate as expected after you change type of the SettingID property and the _SettingID field to Nullable<int> (int?):
[Serializable()]
public class UsrScanCoSettingItem : IBqlTable
{
#region SettingID
public abstract class settingID : PX.Data.IBqlField
{
}
protected int? _SettingID;
[PXDBIdentity(IsKey = true)]
public virtual int? SettingID
{
get
{
return this._SettingID;
}
set
{
this._SettingID = value;
}
}
#endregion
...
}

Answer 2

The problem is that in aspx you have the first column defined as:
<px:PXGridColumn DataField="Seleted" ...
While the name of the column you want is Selected. Looks like it is as easy as that.

Answer 3

I've been where you are and I think to solve it I had to build the list. Try something like the following.
//Invoices.SetProcessDelegate(SendData);
Invoices.SetProcessDelegate(delegate(List<ARInvoice> list)
{
List<ARInvoice> newlist = new List<ARInvoice>(list.Count);
foreach (ARInvoice doc in list)
{
newlist.Add(doc);
}
SendData(newlist);
});
