Hi,
i copied an editor xml from one entity to the next. Unfortunately there was a attribute which was not part of the entity of the new editor.
I got an exception that was pretty hard to reason about.
java.lang.ClassCastException: java.lang.String cannot be cast to com.haulmont.chile.core.model.MetaPropertyPath

I figured out the reason but not because of the Stacktrace but rather looking at the XML file.
This post is because if anyone has the error it will be crawled by google. So if you have this problem: take a look at your xml file and see if every property in the table / treetable (as in my case) is available in the entity.
Additionally: would it be possible to get a proper error message so that the developer get a hint on what to look at?
That would be great!
Bye,
Mario
