How can I keep a user field from coming through on a Journal Entry release function?

Question

I have a customization to the Journal Transactions screen where I've added a user field to the grid (GLTran). When the Release function is initiated, it adds lines as it should - but it populates the user field with the values I had in the original lines, and I don't want this to happen. How can I intercept this process (I've looked at the source code and I can't see any functions I can use) to prevent this from happening?

I've tried the RowInserting / RowInserted events to set the field to null or blank, but this does nothing.

Thanks much -

From Acumatica support - an override of the Release process needs to be added to the Journal Entry BLC extension code, adding Event handlers as follows:

    public delegate IEnumerable ReleaseDelegate(PXAdapter adapter);
    [PXOverride]
    public IEnumerable Release(PXAdapter adapter, ReleaseDelegate baseMethod)
    {
        PXGraph.InstanceCreated.AddHandler<PostGraph>((graph) =>
        {
            graph.RowPersisting.AddHandler<GLTran>((sender, e) =>
            {
                var gltran = e.Row as GLTran;
                if (gltran != null)
                {
                    var gltranext = PXCache<GLTran>.GetExtension<GLTranExt>(gltran);
                    gltranext.UsrProject = null;
                }
            });
        });

        return baseMethod(adapter);
    }

Thanks much, Cesar!
