How are you supposed to use GuiConfigEntries.SelectValueEntry?

I'm going to go insane. As with almost everything Forge there is basically no documentation to be found. I wanted to use the SelectValueEntry GUI entry in the same fashion I use numeric sliders - by telling Configuration Properties about this nice ConfigEntry class:

 

File configFile = event.getSuggestedConfigurationFile();
config = new Configuration(configFile);
config.get("Category", "Field", "Default").setConfigEntryClass(GuiConfigEntries.SelectValueEntry.class);

Naturally that doesn't work because the relevant constructor then doesn't know about SelectValueEntry's fourth required parameter that gives it the map with values.

I tried a bunch of different  things; mainly the least  ugly override of the class like so:

public class MySelectValueEntry extends GuiConfigEntries.SelectValueEntry {
	public MySelectValueEntry(GuiConfig owningScreen, GuiConfigEntries owningEntryList, IConfigElement configElement) {
		super(owningScreen, owningEntryList, configElement,  ValueMap);
	}
}

where ValueMap is a previously constructed Map<Integer, String>, and just using it there instead. Seemed like a fairly okay solution, but I was met with an exception:

[01:59:12] [main/ERROR] [FML]: There was a critical error instantiating the custom IConfigEntry for config element cfg.field.

suggesting that a fitting  constructor(?) doesn't exist. You can look at the full and pretty much current source code for context. I specifically don't want to draw the menu "by hand" (thus bypassing the whole instantiation from net.minecraftforge.fml.client.config.GuiConfigEntries:126) to avoid duplicating tons of code that already works just fine inside Forge.

Did I miss something or am I doing it somehow completely wrong? I've been trying at it for the past like 4 hours without much recourse. Any ideas?
