Minor Update Makes Content Not Accessible

JesseDevelops · November 20, 2025, 5:20am

Updating from previous minor version to 16.3.4 some of my custom content types with appear to not show in the dropdown. I’ve done everything I could think of, indexes, cache restart etc.

This is how it appears in my umbraco backend Screenshot by Lightshot

Error in console - context-consumer.js:194 Uncaught (in promise) Context request was cancelled, host was disconnected. (Context Alias: UmbModalContext with API Alias: default). Controller is hosted on #document-fragment > UMB-INLINE-LIST-BLOCK

How do i fix this so I can upgrade a few of my projects to the latest without having content errors?

Hi @JesseDevelops

This does look like exactly this issue:

### Which Umbraco version are you using? 16.3.2, 17.0.0-beta ### Bug summary …When you have a block list set to use 'inline editing mode', any block that has tabs will not work. It will show the tabs, but not the content of the tabs: <img width="1120" height="350" alt="Image" src="https://github.com/user-attachments/assets/ad68c9a5-fa45-476a-bfe7-c805881b213d" /> ### Specifics - ### Steps to reproduce 1. Create an element type with tabs and add one or more properties to the tabs: <img width="790" height="367" alt="Image" src="https://github.com/user-attachments/assets/5fb4f242-ee62-4101-b069-72606b5d0d0e" /> 2. Add a new block list data type, add the block created in step 1 and set it for inline editing mode: <img width="1023" height="1128" alt="Image" src="https://github.com/user-attachments/assets/545942d8-53fc-42d2-ba3e-2f8d8377ae0a" /> 3. Create a document type that uses that block list and set it to 'allow at root', so we insert it: <img width="1053" height="377" alt="Image" src="https://github.com/user-attachments/assets/5bcee771-02aa-4ae2-ae1d-a47a17fc3e10" /> 4. When you add the block, it will show the tabs - and you can switch between the tabs - but the content of the tab will not be displayed: <img width="1152" height="321" alt="Image" src="https://github.com/user-attachments/assets/ad605ec1-4ca7-4651-bfee-5d85f415eb3e" /> ### Expected result / actual result Obviously I expect the content of the tabs to show so that I'm able to edit the fields the are on the tabs. --- _This item has been added to our backlog AB#61219_

Fixed by this PR:

Taking part in v16.4 and 17.0

So hopefully it works for you if you upgrade to one of the RCs or to the final releases coming very soon.
