Liferay.Service(...) causes JS error "a.Array.filter is not a function"

[Harri Tuomela, modificado 8 Anos atrás.]

Hi! I've implemented a custom jsonws and http://localhost:8080/api/jsonws/LiferayLayoutRelation-portlet.layoutrelation/get-public-layouts/company-id/10155/locale/fi_FI returns JSON array [["Test",2],["Welcome",1]]. However, when I try to access this service from portlet's view.jsp like this

<aui:script>
    Liferay.Service(
        '/LiferayLayoutRelation-portlet.layoutrelation/get-public-layouts',
        { "companyId": 10155, "locale": "fi_FI" },
        function(obj) { console.log(obj); }
    );
</aui:script>

I get a JavaScript error "Uncaught TypeError: a.Array.filter is not a function" which is caused by this statement in everything.jsp:

var o=a.Array.filter(m,d.isFunction);

How can I access custom jsonws from JavaScript?

Hi!
Please add this snippet to your URL:
&js_fast_load=0&css_fast_load=0&strip=0

this will give you a better insight on what actually is failling. I have encountered this error, when there was a different error with my JavaScript. Not with the actual Service Call, but in some other part. Please take a look with Firebug (or any other tool) on the Java Script Console, if there are any traces where the error occured. (Disable js_fast_load though ;) )

Thanks Jan!

The problem is caused by liferay.js row 94:

var callbacks = A.Array.filter(args, Lang.isFunction);

which is in the call stack originated by call to Liferay.Service(...).

I still have no idea how to cope with this issue.

In the /api/jsonws view, you can get sample code of your Method. Did u try to execute that snippet generated?

Also try this one:

<aui:script>
    Liferay.Service(
        '/LiferayLayoutRelation-portlet.layoutrelation/get-public-layouts',
        { companyId: 10155, locale: "fi_FI" },
        function(obj) { console.log(obj); }
    );
</aui:script>

I actually started with /api/jsonws generated JS:

Liferay.Service(
  '/LiferayLayoutRelation-portlet.layoutrelation/get-public-layouts',
  {
    companyId: 10155,
    locale: 'fi_FI'
  },
  function(obj) {
    console.log(obj);
  }
);

It produces the error and so does your sample code.

The method filter is provided by the YUI module "array-extras". Adding it to solved the problem.

<aui:script use="array-extras">
    Liferay.Service(...);
</aui:script>
