+1. Can you please document the method?
> Make default dimension config in FacetConfig adjustable

> 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?)
