MVVM : The binding is from a different library -> assert in cooked editor

Hi Epic,

Since 5.6.1 we have started seeing this assert hit when using MVVM UMG Plugin in cooked editor.

FMVVMCompiledBindingLibrary::ExecuteImpl

ensureAlwaysMsgf(false, TEXT(“The binding is from a different library.”));

This used to be fine in 5.5 and looking through the history there is nothing obvious that stood out. So any insights into this would be appreciated.

We are relying on MVVM plugin extensively so having this functional in a cooked editor flow is something we’d like to have moving forward.

Thank you.

Kind Regards,

Abhi

Hi,

Can you post a full callstack from the moment when you hit that assert? That should help us narrow down what might have changed between 5.5 and 5.6 to cause this.

Best,
