I am attempting to completely replace the default Case Workflow via code.

I copied nearly the entire default CaseWorkflow code and customized it to my liking. However, I am not able to make the changes display in any way.

Some important bits of code are:

namespace CaseTest
{
    using static PX.Data.WorkflowAPI.BoundedTo<CRCaseMaint, CRCase>;

    public class CaseWorkflow_CRCaseMaint_Workflow : PXGraphExtension<CRCaseMaint>
    {
        public static bool IsActive() => true;

        public override void Configure(PXScreenConfiguration config)
        {PXTrace.WriteInformation("!");
            var context = config.GetScreenConfigurationContext<CRCaseMaint, CRCase>();

            context.ReplaceScreenConfigurationFor(screen =>
            {
                return screen
                    .StateIdentifierIs<CRCase.status>()
                    .FlowTypeIdentifierIs<CRCase.caseClassID>(true)
                    .WithFlows(flows =>
                    {
                        flows.AddDefault(DefaultCaseFlow);
                    })
                    // ....

 And the customized workflow:

            Workflow.IConfigured DefaultCaseFlow(Workflow.INeedStatesFlow flow)
            {
                //....

Can anyone see any issues here? I attached the whole code file just in case someone wants to work through it. Just rename the file extension to .cs and it will open in Visual Studio.
