> Now it is hardcoded to DEFAULT_DIM_CONFIG. This may be useful for most standard approaches.

> However, I use lots of facets. These facets can be multivalued, I do not know that on
beforehand. So what I would like to do is to change the default config to {{mulitvalued =
true}}. 
> Currently I have a working, but rather ugly workaround that subclasses FacetConfig, like
this:
> {code:title=CustomFacetConfig.java|borderStyle=solid}
> public class CustomFacetsConfig extends FacetsConfig
> {
> 	public final static DimConfig DEFAULT_D2A_DIM_CONFIG = new DimConfig();
> 	static
> 	{
> 		DEFAULT_D2A_DIM_CONFIG.multiValued = true;
> 	}
> 	@Override
> 	public synchronized DimConfig getDimConfig( String dimName )
> 	{
> 		DimConfig ft = super.getDimConfig( dimName );
> 		if ( DEFAULT_DIM_CONFIG.equals( ft ) )
> 		{
> 			return DEFAULT_D2A_DIM_CONFIG;
> 		}
> 		return ft;
> 	}
> }
> {code}
> I created a patch to illustrate what I would like to change. By making a protected method
it is easier to create a custom subclass of FacetConfig. 
> Also, maybe there are better way to accomplish my goal (easy default to multivalue?)
