Hi!

We've just update DNN from 8.0.4 to 9.0.1 and if you want to add a module (existing or new) we get a JavaScript error. This happens on all pages except home

Uncaught TypeError: Cannot read property 'data' of null
    at Object.onClick (AddModule.js?cdv=431:17)
    at main.js?cdv=431:182
    at main.js?cdv=431:103
    at Object.init (AddModule.js?cdv=431:10)
    at main.js?cdv=431:101
    at Object.execCb (require.js?cdv=431:1650)

    at require.js?cdv=431:132
    at require.js?cdv=431:1156

I already added an issue to DNN Tracker (see https://dnntracker.atlassian.net/browse/DNN-9329) but they closed because they could not reproduce it. I want to look into it (see comments in the issue) but I do not get any support...

Can somebody help me understand the code below and what might be causing the problem? See below of what's happing within the code

It's not getting any data on the following function on DesktopModules/Admin/Dnn.EditBar/scripts/addModule.js:

var onClick = function () {
        var dialog = window.top.dnn.ContentEditorManager.getModuleDialog(); /* this one return an object */
        var contentPane = dialog.getDefaultPane(); /* this one is null */
        var moduleManager = contentPane.data('dnnModuleManager'); /* here it breaks */
        if (moduleManager) {
            moduleManager.getHandler().click();
        }
    }

what does moduleManager expect from the dialog.getDefaultPane() function and where is this based upon?

Thanks in advance!

Hi Brad,

Thank you for sharing your experience with the issue. It's however not something I can reproduce on my side. :(

What I did find out was that it's related to the fact that if a container is not a <div> element bit an HTML5 element like <section> or <article> it breaks on these symptoms. I've also posted it on the JIRA of DNN: https://dnntracker.atlassian.net/browse/DNN-9508?filter=-2

Maybe it is something you can relate to as well?
