Why does my PXSelector ignore what I have selected - acumatica

Question

I have created a PXGraphExtension on POLandedCostDocEntry. I have added a PXAction button. When the button is pressed I show a popup panel to ask the user for a landed cost code.
The problem is that the PXSelector ignores whatever I enter into the field and resets to APPLE (or whatever Landed Cost Code is alphabetically first). If I use the Selector to choose a different code, the code I select is visible for a moment and then immediately replaced with APPLE again.
The ASPX for the popup dialog is as follows:
<px:PXSmartPanel runat="server" ID="PanelAskForLCCode" LoadOnDemand="True" AutoRepaint="True" Key="LandedCostCodeSelection" CaptionVisible="True" Caption="Select Landed Cost Code" AcceptButtonID="CstButton4" CancelButtonID="CstButton5">
<px:PXPanel runat="server" ID="CstPanel9">
<px:PXFormView runat="server" ID="CstFormView10" SkinID="Transparent" Width="100%" SyncPosition="True" DataMember="LandedCostCodeSelection" DataSourceID="ds">
<Template>
<px:PXSelector runat="server" ID="CstPXSelector11" DataField="LandedCostCodeID" CommitChanges="True" DataSourceID="ds">
</px:PXSelector>
</Template>
</px:PXFormView>
</px:PXPanel>
<px:PXPanel runat="server" ID="LandedCostCodeSelectionButtons" SkinID="Buttons">
<px:PXButton runat="server" ID="CstButton4" DialogResult="OK" Text="OK" />
<px:PXButton runat="server" ID="CstButton5" DialogResult="Cancel" Text="Cancel" />
</px:PXPanel></px:PXSmartPanel>
The code for the view that I'm referencing in the dialog is:
public PXSelect<LandedCostCode> LandedCostCodeSelection;
The code that I'm using to call the dialog is:
if (LandedCostCodeSelection.AskExt() == WebDialogResult.OK)
{
//rest of code here
}
What am I missing to allow the user to select or type a different Landed Cost Code?
Edit 1:
I have changed the code for the view that I'm referencing in the dialog to:
public PXFilter<LandedCostCode> LandedCostCodeSelection;
My aspx now looks like this:
<px:PXSmartPanel runat="server" ID="PanelAskForLCCode" Key="LandedCostCodeSelection" CaptionVisible="True" Caption="Select Landed Cost Code" AcceptButtonID="CstButton4" CancelButtonID="CstButton5" Width="300px" AutoRepaint="True" LoadOnDemand="True">
<px:PXFormView runat="server" ID="CstFormView18" CaptionVisible="False" Caption="LC Code Selection" DataSourceID="ds" DataMember="LandedCostCodeSelection">
<Template>
<px:PXLayoutRule runat="server" ID="CstPXLayoutRule19" StartColumn="True" ControlSize="XM" LabelsWidth="S"/>
<px:PXSelector runat="server" ID="CstPXSelector20" DataField="LandedCostCodeID" CommitChanges="True" DataSourceID="ds" DataMember="LandedCostCodeSelection"/>
</Template>
<CallbackCommands>
<Search CommitChanges="True"/>
</CallbackCommands>
</px:PXFormView>
<px:PXPanel runat="server" ID="LandedCostCodeSelectionButtons" SkinID="Buttons">
<px:PXButton runat="server" ID="CstButton4" DialogResult="OK" Text="OK"/>
<px:PXButton runat="server" ID="CstButton5" DialogResult="Cancel" Text="Cancel"/>
</px:PXPanel>
</px:PXSmartPanel>
I'm calling the dialog as follows:
if (LandedCostCodeSelection.AskExt((graph, view) =>
{
LandedCostCodeSelection.Cache.Clear();
},true) == WebDialogResult.OK)
{
}
I notice that when I click on the selector button and pick a row from the selector (which briefly returns a value to the field which is then overwritten right away) when I click on the selector button again, the selector has remembered the record I last selected.
Finally, if I invoke the dialog as follows:
if (LandedCostCodeSelection.AskExt((graph, view) =>
{
LandedCostCodeSelection.Cache.Clear();
LandedCostCodeSelection.Current.LandedCostCodeID = "XYZ";
},true) == WebDialogResult.OK)
{
}
Then the field is populated with XYZ and if I click OK I can reference the value of XYZ. (But if I use the selector, then the value is cleared and cannot be accessed again.)

The problem relies in the definition of the DataView and the DAC used. I have reproduced the issue and this is what I've changed to make it work:
Use a new custom DAC as a source for your view. Note that the field is not bound and is not key (does not have IsKey = true, as in LandedCostCode.LandedCostCodeID:
[Serializable]
[PXHidden]
public partial class LandedCostCodeFilter: IBqlTable
{
#region LandedCostCodeID
public abstract class landedCostCodeID : PX.Data.BQL.BqlString.Field<landedCostCodeID> { }
[PXString(15, IsUnicode = true)]
//[PXUnboudDefault("APPLE")] //optional, to preselect a value
[PXUIField(DisplayName = "Landed Cost Code",Visibility=PXUIVisibility.SelectorVisible)]
[PXSelector(typeof(Search<LandedCostCode.landedCostCodeID>))]
public virtual String LandedCostCodeID {get; set}
#endregion
}
Change the DataView definition, using a PXFilter instead of PXSelect and use the new DAC
public PXFilter<LandedCostCodeFilter> LandedCostCodeSelection;
Correct that and your dialog should work.
Obs.
If you want to have a value pre-selected when you open the dialog, add [PXUnboudDefault("APPLE")] to the field in the DAC
Not sure how does your button definition look like, but here is what it should be:
public PXAction<POLandedCostDoc> SelectLandedCost;
[PXButton]
[PXUIField(DisplayName = "Select Landed Cost Code", MapEnableRights = PXCacheRights.Delete, MapViewRights = PXCacheRights.Delete)]
protected void selectLandedCost()
{
if(LandedCostCodeSelection.AskExt(true) != WebDialogResult.OK) return;
// do some stuff here
}
Also, my aspx code:
<px:PXSmartPanel runat="server" ID="PanelAskForLCCode" Caption="Select Landed Cost Code" CaptionVisible="True" Key="LandedCostCodeSelection">
<px:PXFormView runat="server" ID="CstFormView2" DataMember="LandedCostCodeSelection" SkinID="Transparent" DataSourceID="ds" Height="100%" Width="100%">
<Template>
<px:PXLayoutRule runat="server" ID="CstPXLayoutRule3" StartColumn="True" />
<px:PXSelector runat="server" ID="CstPXSelector4" DataField="LandedCostCodeID" CommitChanges="True" AutoRefresh="True" />
<px:PXPanel runat="server" ID="LandedCostCodeSelectionButtons" SkinID="Buttons">
<px:PXButton runat="server" ID="CstButton6" DialogResult="OK" Text="OK" />
<px:PXButton runat="server" ID="CstButton7" DialogResult="Cancel" Text="Cancel" /></px:PXPanel></Template></px:PXFormView></px:PXSmartPanel>
