java - Hibernate @Any Annotation and Multiple Join Columns (ie: Composite Key) -

-

is possible use hibernate @any annotation when object being mapped has composite key? have tried following annotation combination: 

@any(metacolumn = @column(name = 'meta_column')) @anymetadef(idtype = 'string', metatype = 'string', metavalues = [     @metavalue(value = 'v1', targetentity = object1),     @metavalue(value = 'v2', targetentity = object1),     @metavalue(value = 'v3', targetentity = object2) ]) @joincolumns([     @joincolumn(name = 'column1'),     @joincolumn(name = 'column2'),     @joincolumn(name = 'column3') ])

unfortunately results in 

org.hibernate.mappingexception: property mapping has wrong number of columns: ca.package.class type: object

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
