Firstly, I'm not against Media Picker v3 introduced in 8.14 as I'm a big fan of it's features and what it has to offer. However, I was forced to revert a data type back to v2 due to a console log error I was unable to find a solution for and was kind of urgent for me to find a solution due to a deadline on a project.

So I was mid project build when I decided to do an upgrade (not usually an issue). By this point I had already created a few pages and many fields with references to Media Picker v2. Anyways, not an issue I decided I'd just continue the build with a hybrid of media pickers by opting to adopt v3 henceforth.

Unfortunately whilst I was trying to configure a v3 data type I was unable to click options such as "Accepted Types" or "Image Crops". Looking in the console log I found I was getting "The controller with the name 'Umbraco.PropertyEditors.MediaPicker3.CropConfigurationController' is not registered.". Googled it and couldn't find an issue and really needed a solution ASAP.

Lightbulb moment... uSync! After comparing the .config files for an existing v2 & v3 data type I found that there were small subtle differences in the configuration, so I decided to change the <EditorAlias> and copied the <Config>. Did a uSync import and hey presto my data type is back to the old school media picker. There's a reason why it's award winning!

I'd be interested to know however why I was getting a console log error and why it wasn't working post upgrade. It'd be great to offer the option to change between the v2 and v3 so I don't have to resort to using uSync to perform this hack, but no doubt there were reasons at HQ for doing so.
