Creating a simple colorpicker based on a field in a table

I extended the ReqParameters table with an int field, named ProductionQuantitiesColor.

I then extended the form with the same name and added a formcontrol for my field.

I found an existing Microsoft dropdown on the form JmgProfileTable:

[DataSource]
class JmgProfileTable
{
    public int active()
    {
        int ret;
        ret = super();
        displayColor.backgroundColor(jmgProfileTable.Color);
        return ret;
    }


    [Control("Integer")]
    class displayColor
    {
        public void lookup()
        {
            jmgProfileTable.Color = ColorSelection::selectColor(this, jmgProfileTable.Color);
            displayColor.backgroundColor(jmgProfileTable.Color);
        }

    }
}

So I wanted to create the same logic for my reqParameters extension, so I added the following code:

[ExtensionOf(formControlStr(ReqParameters, ProductionQuantitiesColorCtrl))]
final class FormDF_ReqParameters_ProductionQuantitiesColorCtrl_Extension
{
    public void lookup()
    {
        next lookup();
        this.lookup_post();
    }

    public void lookup_post()
    {
         FormDataSource formDatasource = this.formRun().dataSource(tableStr(ReqParameters));
         ReqParameters reqParameters = formDatasource.cursor();
         reqParameters.ProductionQuantitiesColor = ColorSelection::selectColor(this, reqParameters.ProductionQuantitiesColor);
         this.backgroundColor(reqParameters.ProductionInstructionsColor);
         reqParameters.write();
    }
}


[ExtensionOf(FormDataSourceStr(ReqParameters, ReqParameters))]
internal final class FormDS_ReqParameters_ReqParameters_Extension
{
    public int active()
    {
        int ret = next active();
        this. active_post(ret);
        return ret;
    }

    public int active_post(int ret)
    {     
        ReqParameters reqParameters = this.cursor() as ReqParameters;
        if(reqParameters)
        {
            int color =  reqParameters.ProductionQuantitiesColor;
            FormIntControl  formControl  = this.formRun().control(this.formRun().controlId(formControlStr(ReqParameters,                                ProductionQuantitiesColorCtrl)));
            formControl.backgroundColor(reqParameters.ProductionQuantitiesColor);
        }
        return ret;
    }
}

The only thing I added is the call to reqParameters.write(), in order to make sure the value gets stored.

The integer value gets saved correctly and I also get a colorpicker via the lookup if I open the dropdown.

However, when rendering the screen the colorpicker always stays white. I even check in a breakpoint that the call to fromControl.backgroundColor in the datasource's active extension is being called correctly and has the correct integer value as well.

Does anyone know what I could be missing here?
