---------------------------------------
Assignee: Christopher Lenz
> undefined in an array as a key causes an Erlang error
> -----------------------------------------------------
>
> Key: COUCHDB-83
> URL: https://issues.apache.org/jira/browse/COUCHDB-83
> Project: CouchDB
> Issue Type: Bug
> Components: JavaScript View Server
> Affects Versions: 0.7.2, 0.8
> Reporter: Ryszard Szopa
> Assignee: Christopher Lenz
>
> Whenever a view emits an array containing undefined as a key an Erlang is
> thrown:
> For example, if there's at least one document in the db without foo being
> set, the following view
> function(doc) {
> emit([doc.foo], doc);
> }
> triggers
> {{nocatch,{bad_value,"Cannot encode 'undefined' value as JSON"}},
> [{couch_query_servers,prompt,2},
> {couch_query_servers,'-map_docs/2-fun-0-',2},
> {lists,map,2},
> {couch_query_servers,map_docs,2},
> {couch_view,view_compute,2},
> {couch_view,update_group,1},
> {couch_view,temp_update_loop,2}]}
> OTOH,
> function(doc) {
> emit(doc.foo, doc);
> }
> causes no problems.
