$stateParams array value is converted to string when single element

[crystalneth]

When calling $state.go('app.foo', {someArray: ['a']}), the $stateParams.someArray is received as 'a'. When there are multiple values, it is received correctly as an array. This makes consistent processing difficult.

Is it in a query parameter? If so, force the 'array mode' to true: params: { someArray: { array: true } }

Can you show me the app.foo definition?

It's well work for me. But if use [] in place new Array() array can be cast to a string

url: 'posts?s&tags&page',
params: { s: null, tags: new Array(), page: null },
templateUrl: "/static/templates/posts/posts.html",

I'm seeing the same behavior, works with more than one array member, but an Array of length 1 or less isn't an array, but a single value. Using the alternate syntax ?kind[]=example would work here

export const index = { name: RESOURCE_INDEX, url: '/search?kind', data: { authenticate: true }, params: { kind: { array: true }, view: null }, component: Search }
