Passing array from JScript to COM object: Error converting argument 1 to type class StringArray

[FrankLeinbach]

I have run into a breaking issue in moving from an implementation I made of IActiveScript to ClearScript.

I have JScript that creates a COM object like this:

var thirdPartyObj = new ActiveXObject("ThirdPartyObj.API");

within the script, I also create an array of strings to pass to a method on this object:

var stringData = [];
stringData.push("String1");
stringData.push("String2");
stringData.push("String3");

In the previous iteration, I had a problem directly calling the third party object's method with this array, like this:

thirdPartyObj.ProcessStrings(stringData)

This gave me an error. To circumvent this, I created a global host object function that simply took the JavaScript array and returned an array of String (string[]).

thirdPartyObj.ProcessStrings(JSArrayToStringArray(stringData));

This worked in the original IActiveScript implementation.

Now, with ClearScript, every time I pass this to the ProcessStrings function, regardless of passing it directly or wrapping the array in the function, I get the error "Error converting argument 1 to type class StringArray".

I have tried a number of engine properties, but none have worked:

AllowReflection
DisableListIndexTypeRestriction
DisableTypeRestriction
EnableAutoHostVariables
EnforceAnonymousTypeAccess
UseReflectionBindFallback

Any insight would be appreciated.
