Missing PropertyEditor for Composite Keys in MVC controllers

Support was added for composite primary keys a while ago (https://jira.spring.io/browse/ROO-1982) but in order to make a successful request to a controller that takes a composite primary key ID as a parameter, Spring Roo doesn't create the necessary PropertyEditor in order to submit two or more id values in the url.

So when trying to make a request to a controller like:

public ResponseEntity<String> CommunityUserController.showJson(@PathVariable("id") CommunityUserPK id) {
        CommunityUser communityUser = communityUserService.findCommunityUser(id);

you get the error:

2014-08-21 09:32:05,356 [tomcat-http--3] DEBUG org.springframework.beans.BeanUtils- No property editor [community.model.CommunityUserPKEditor] found for type community.model.CommunityUserPK according to 'Editor' suffix convention
