User Custom Actions not working in Version 2016


  • Hi Experts,

    this Issue is about SharePoint-Online 2016.

    I deployed some ScriptLink through User Custom Actions (Web) and a link to Location Microsoft.SharePoint.SiteSettings.

    None of these are working. From the Development-Tools in Edge i can see that the Script-Files are not loaded.

    If I Change the UI to Classical View everything is working as expected.

    Am I missing some new Rules in 2016?

    Hope you can Help, Best Regards, Ronny

  • Hi Ronny,

    Could you please share how you deploy the ScriptLink for us to reproduce this issue?

    And as a workaround for now, you can add the JS reference in master page.

  • Hi Victoria,

    sorry about my late Response. These are busy times :)

    Custom Actions are Installed over SSOM, CSOM & JSOM (depends on Product and Platform).

    Please note that this is working in Production (SP2013 On-Premise & SP 2013 Online) since two years!

    During our Tests on SP 2016 to identify if we might have a Migration issue we run into mentioned Problem.

    Here is one (JSOM) Code snippet to install a css-link as UCA to a Web:

    var caClientContext = SP.ClientContext.get_current();
    var oWebsite = caClientContext.get_web();
    var collUserCustomAction = oWebsite.get_userCustomActions();
    var oUserCustomAction = collUserCustomAction.add();
    var oUserCA3 = collUserCustomAction.add();
    oUserCA3.set_description('This has link-Reference to Root-Web Style Library SP2013Accordion.css.');
    var scriptBlock = "var headID=document.getElementsByTagName('head')[0];";
    scriptBlock += "var newScript=document.createElement('link');";
    scriptBlock += "newScript.type='text/css';";
    scriptBlock += "newScript.rel='stylesheet';";
    var webServerRelativeUrl = _spPageContextInfo.webServerRelativeUrl;
    if (webServerRelativeUrl === "/") {
    	// No sub site, just root.
    	scriptBlock += "newScript.href='" + _spPageContextInfo.webServerRelativeUrl + "Style Library/Company CSS/SP2013Accordion.css';";
    else {
    	// the subsite has no trailing end of /.
    	scriptBlock += "newScript.href='" + _spPageContextInfo.webServerRelativeUrl + "/Style Library/Company CSS/SP2013Accordion.css';";
    scriptBlock += "headID.appendChild(newScript);";
    function () {
    	alert("CompanyAccordionCssLink has been successfully added.");
    function (sender, args) {
    	alert("Request to add User Custom Action CompanyAccordionCssLink to Web failed. " + '\n' + args.get_message() + '\n' + args.get_stackTrace());
    Please note that none of the UCA will be loaded (Remeber: Production-Code working in 2013)

    Due to the Major changes in 2016 (e.g sidenavbox => <nav>-TAG) it seems that the guys in Redmond changed API and Interface?

    Please involve somebody with Knowledge on this.

    With Best Regards, Ronny
