blank row being added on insert - acumatica

Question

I have a very simple Maint page, it has no events
public PXCancel<RCDistributorSalesStat> Cancel;
public PXSave<RCDistributorSalesStat> Save;
public SelectFrom<RCDistributorSalesStat>.View Records;
and everytime I save the first record entered I get an error and it has added a second blank line and throws errors that required fields are missing.
I found a similar question to this on here about having multiple ISKey set, though I only have one.

I am unsure what is causing the unwanted row to try and persist.

Answer 1

I have changed my keys around, I removed my IsKey on the PXDBIdentity and set two other fields as the key in the DAC and the DB. That seems to have the desired effect as no blank row gets created during Save. Upon further testing it appears that for our listview page I was missing "px:Selector" rows inside of my RowTemplate in my Grid.
