Getting TypeConverter error that makes no sense

I have a TypeConverter for a TopMostNode class. It extends ExpandableObjectConverter. The TopMostNode has two properties. Setting those in the property grid results in correctly serialized code to the designer. However, if I type in text for the property, I get a "Property value is not valid" error and the details say:

Object of type 'TopMostNode' cannot be converted to type 'TopMostNode'.

I'm baffled. When I step through the type converter ConvertFrom code, it runs as expected. I don't even know were to start looking for an issue like this.

Solution

  • You probably have two different versions of the same assembly loaded.
