Acumatica - creating a simple detail screen with header - acumatica

Question

Acumatica is seriously gonna make me cry. I have followed the tutorial in T100 to create a simple inquiry screen. When I open it, the screen is blank. I can see the layout in design view, when I load the screen it is blank.
My graph:
public class QLInventoryMaint : PXGraph<QLInventoryMaint>
{
public QLInventoryMaint()
{
ResponseRec.Cache.AllowInsert = false;
ResponseRec.Cache.AllowDelete = false;
ResponseRec.Cache.AllowUpdate = false;
}
[Serializable]
public class StrainFilter : IBqlTable
{
#region DisplayID
public abstract class displayID : PX.Data.IBqlField
{
}
protected String _DisplayID;
[PXString(4)]
[PXUIField(DisplayName = "Display ID")]
public virtual String DisplayID
{
get
{
return this._DisplayID;
}
set
{
this._DisplayID = value;
}
}
#endregion
}
public PXCancel<StrainFilter> Cancel;
public PXFilter<StrainFilter> StrainFilterRec;
[PXFilterable]
public PXSelectReadonly<StrainResult, Where<StrainResult.displayID, Equal<Current<StrainFilter.displayID>>>> ResponseRec;
}

I wanted originally to create a lookup screen with no database fields, but I was getting the same result. I decided just o follow tutorial and create inquiry screen. I hate this framework.

Answer 1

My guess is the Current<> display ID is not getting set so the query for the grid is empty. You can do a SQL trace to confirm but I would use CommitChange="True" on the filter field in your page...
<px:PXTextEdit ID="edDisplayID" runat="server" AlreadyLocalized="False" DataField="DisplayID" CommitChanges="True">

It appears that FormDetail creation does not work in 17.204.0019. I created the screen in 17.202.0016 and it worked fine. I imported the screen into 17.204.0019 and it also worked. Can anyone confirm or deny this?
