> while investigating an issue involving {{sling:alias}}, i ended up manually adding the property using JCR API calls. this involved first adding the {{sling:ResourceAlias}} and i noticed that {{sling:alias}} can be both single or multi-valued according to the node type definition:
> {code}
> / Mixin node type to enable setting an alias on a resource
> [sling:ResourceAlias]
> mixin
>
> // alias name(s) for the node (single or multi-value)
> - sling:alias (string)
> - sling:alias (string) multiple
> {code}
> when setting multiple values for the {{sling:alias}} property, i found that {{ResourceMapper.getAllMappings}} only returns the first alias.
> looking at the implementation in {{ResourceMapperImpl.loadAliasIfApplicable}}, it seems that line 216 ({{String alias = ResourceResolverControl.getProperty(current, ResourceResolverImpl.PROP_ALIAS);}}), is the culprit as call will in any case just return a single string (it calls {{getProperty(res, propName, String.class)}}).
> as a consequence consumers of the {{ResourceMapper.getAllMappings}} method will not get a complete list of all aliases available.
