Error: TypeError: Cannot read property '_destroyed' of undefined when pasting data

[edwinvanelk]

When data is pasted from some (other) Mendix app, a <DIV> tag with a property like [widgetid="mxui_widget_TextArea_24"] is added to the text in the CKEditor:

for example:

<div data-mendix-id="561_3" focusindex="0" id="mxui_widget_TextArea_24" style="text-align:left" widgetid="mxui_widget_TextArea_24"> waterschade</div>

When leaving the page containing the CKEditor with this text (by saving or even using cancel button) , Mendix gives an error:

Cannot read property '_destroyed' of undefined TypeError: Cannot read property '_destroyed' of undefined

After removing the [widgetid] property from the <DIV> tag in the text, error is gone.

This is an issue with Microsoft Edge and Mendix 6/7. Upgrade to 6.10.13 or 7.16. See the releasenotes. Here's the same error on the forum

I am closing the issue as it is not related to the widget.

[edwinvanelk]

Before entering this issue I reproduced the issue in Mx 7.16.0 (build 36935) using the CKEditor 2.4.8 widget.

Not using MS Edge, issue was reproduced using Chrome 67.0.3396.99.

Issue might not be related to the widget, but problem is not yet solved in 7.16

After reading the forum post (Release notes do not show any details about the "Cannot read property '_destroyed' of undefined" error) it seems that some changes are made to the case of "widgetId" or "widgetid".

But why does some pieces of HTML data which is shown/edited inside the CKEditor cause an error in the Mendix app? Shouldn't this data/htm/text be isolated from the Mendix app?

[JelteMX]

Then it's an issue with the implementation of your html. widgetid is being used by Dojo/Mendix to identify a widget element in the DOM. Adding this yourself is prone to errors, because it isn't a widget. So you should never add these things to the HTML yourself.

What is the reason you add widgetid to the element?

[edwinvanelk]

Jelte,

widgetid gets added to the HTML because notes/data from another (Mendix) application are pasted in our (Mendix) application.

We do not know where the source data is copied from exactly, but the source data seems to contain these Mendix widgetid's.

[JelteMX]

Can you give me an example of what is pasted in there, plus how that is pasted? If this is done through an editor, you might want to apply some sanitation first (which in terms of XSS is a good idea regardless)

We might have to add some sanitation client side, but ultimately this has to be done server side

[edwinvanelk]

Hi Jelte,

Data is copied (to Windows clipboard) from any of the screens from another Mendix application ans pasted directly in our application. No editor is involved, so user is not able to sanitize data.

Complete copy of data that was pasted in CKEditor:
