    SaveImpl() on custom repository doesn't work

    I'm using a custom KonstruktRepository, but the protected override T SaveImpl(T entity) doesn't seem to be working. When I save an entity the custom SaveImpl() method is never hit and I get the following error:

    Sequence contains more than one matching element

    Or am I missing something?

    So it's failing property validation before it event gets to your entity save routine.

    Looking at the code for ValidatePropertyData it would appear it fails when it tries to lookup a configured property in your post model. The ThrowMoreThanOneMatchException would suggest you somehow have more than one property that matches a specific alias.

    I'd check your config / models for duplicate properties.

    I wanted to an "Info label" data type to the top of the editor view which shows some basic instructions. I had to bind it to an entity field in the AddField() method, so I used the Name field, but this field was also being used in another editor field. I've now added a dummy/placeholder field to the entity model that I can use to display the info label:

    And now the SaveImpl() method works as expected.
