How to do lookupReference and resolveReference via Chain of command?

Hi,

I added an int64 "Category" field to "Table1" with Edt "EcoResCategoryId"
then i added this field to Form1

now i want to override the "lookupReference" and "resolveReference" methods of the field in the form datasource, in order to get the tree lookup.

but how to do it?
When i first click on the drop down, it appears as normal lookup and everything appears without filtering the hierarchy role, then if i click on the drop down again, the tree lookup appears and it only shows the correct required data

[ExtensionOf(formDataFieldStr(Form1, Table1, Category))]
final class Form1FormDS_Extension
{
    public Common resolveReference(FormReferenceControl _formReferenceControl)
    {
        Common common;
        common = next resolveReference(_formReferenceControl);
        return EcoResCategory::resolveCategoryHierarchyRole(
                    _formReferenceControl,
                    EcoResCategoryNamedHierarchyRole::Retail);
    }

    public Common lookupReference(FormReferenceControl _formReferenceControl)
    {
        Common common;
        common = next lookupReference(_formReferenceControl);
        return EcoResCategory::lookupCategoryHierarchyRole(
                        _formReferenceControl,
                        EcoResCategoryNamedHierarchyRole::Retail);
    }
}
