[Question] ActionBinding - Resolution in matching entity throwing InvalidCastException when using Custom List Entities

[AndreMantas]

I faced a problem yesterday when the user typed a value that is a list entity which would cause an InvalidCastException to be thrown in the ActionBinding project.

Exception message: Object must implement IConvertible

After some debugging (pictures attached) I found the problem and came up with a temporary fix.

In LuisActionResolver.cs (line ~445)

Before:

if (matchingEntity != null)
{
	var paramValue = matchingEntity.Resolution != null && matchingEntity.Resolution.Count > 0
		? matchingEntity.Resolution.First().Value
		: matchingEntity.Entity;

	result &= AssignValue(action, property, paramValue);
}

After:

if (matchingEntity != null)
{
	var paramValue = matchingEntity.Resolution != null && matchingEntity.Resolution.Count > 0
		? matchingEntity.Resolution.First().Value
		: matchingEntity.Entity;

	if (paramValue is JArray)
	{
		paramValue = (paramValue as JArray).First();
	}

	result &= AssignValue(action, property, paramValue);
}

(and the required imports)

It works for me since I don't have the same synonym in multiple entries.

I could create a pull request but I'm not sure if this is the best approach to solve the problem.
