Acumatica Numbering Sequence - cant default to the new symbol - acumatica

Question

I've got a custom table storing serviceable components within fixed assets. The list is accessed using a grid on the AssetMaint screen.
I've set up an ID field to populate using a numbering sequence. I'm unsure how to set the default so this field populates with "<NEW>" by default, which is then updated by the numbering sequence when the component is saved.
It's sort of working, but there are a few issues. When I click the add button, the ID field is blank, but when I click add again, it populates with the "<NEW>" symbol. However if I add a third record before hitting save, the second record does not populate with "<NEW>". The second record is also not saved, unless I manually put "<NEW>" in the ID field.
This is part of the DAC for the component table:
[Serializable]
public class FAServiceComponent : IBqlTable
{
#region AssetID
public abstract class assetID : IBqlField { }
[PXDBInt(IsKey = true)]
[PXDBDefault(typeof(FixedAsset.assetID), DefaultForUpdate = false)]
[PXParent(typeof(Select<FixedAsset, Where<FixedAsset.assetID, Equal<Current<FAServiceComponent.assetID>>>>))]
[PXUIField(DisplayName = "Asset ID", Visible = false, Enabled = false)]
public virtual int? AssetID { get; set; }
#endregion
#region serviceComponentID
public abstract class serviceComponentID : IBqlField { }
[PXDBString(30, IsKey = true, IsUnicode = true)]
[PXUIField(DisplayName = "Component ID")]
[PXDefault(typeof(Search2<Numbering.newSymbol,
InnerJoin<FixedAsset, On<FixedAssetExt.usrServiceComponentNumberingSeq, Equal<Numbering.numberingID>, And<FixedAsset.assetID, Equal<Current<FixedAsset.classID>>>>>>))]
[Numbering]
public virtual string ServiceComponentID { get; set; }
#endregion
#region serviceComponentDescription
public abstract class description : IBqlField { }
[PXDBString(255)]
[PXUIField(DisplayName = "Description")]
[PXDefault(PersistingCheck = PXPersistingCheck.Nothing)]
public virtual string Description { get; set; }
#endregion
public class NumberingAttribute : AutoNumberAttribute
{
public NumberingAttribute():
base(typeof(Search<FixedAssetExt.usrServiceComponentNumberingSeq, Where<FixedAsset.assetID, Equal<Current<FixedAsset.classID>>>>),
typeof(AccessInfo.businessDate)) {; }
}
}

Check out T200 course available at Acumatica Open University. Part 4 Lesson 8 show you how to use the AutoNumberAttribute.
I would first suggest to remove the following code, as it is not required to make the < New > symbol work.
[PXDefault(typeof(Search2<Numbering.newSymbol,
InnerJoin<FixedAsset, On<FixedAssetExt.usrServiceComponentNumberingSeq, Equal<Numbering.numberingID>, And<FixedAsset.assetID, Equal<Current<FixedAsset.classID>>>>>>))]
You should have a setup screen where you choose the numbering sequence you want to use. As an example, the Sales Orders Preferences screen (SO101000) has the Shipment Numbering Sequence field, bound to SOSetup.ShipmentNumberingID.
In your graph, make sure you have the setup data view, something like public PXSetup<Setup> AutoNumSetup;. The PXSetup DAC should match with your setup screen, e.g. PXSetup<SOSetup> ShipmentSetup
In your DAC, the numbered field should have the AutoNumberAttribute referencing the setup table. e.g.
[AutoNumber(typeof(SOSetup.ShipmentNumberingID), typeof(SOShipment.shipDate))]
In Numbering Sequence screen (CS201010), make sure that Manual Numbering is unchecked and that you have a New Number Symbol set for the numbering sequence you are using.
