Description
When configuring data binding for a TableView, if binding the "title" property on a TableViewRow to a model property, and the model's property is not a string, an argument exception is thrown and the application crashes. I would think that the proxy should accept values not of string type and just convert them.
[ERROR] The application has crashed with an uncaught exception 'NSInvalidArgumentException'.
Reason:
-[__NSCFNumber isEqualToString:]: unrecognized selector sent to instance 0xb23fce0

What other data types would you like to be able to be inserted in the title property? The title property of TableViewRow is only meant to show a title in the form of a string which describes what the Row is. If you want to have any other thing inside the row you can just add to it (such as a view or label). Would you mind elaborating on the benefits of allowing any data type be in the title property? Regards, Carter
This is expected behavior. **title** is a string property.
