Eureka! That was the problem...thank you so much for continuing to think about this!

If you noticed in the code I posted yesterday, I had written:

factory.generateFragments();

instead of something like:

var result = factory.generateFragments();

Apparently the Javascript API to the COM interface is actually sensitive to that, and was not providing anything useful for the 'pVarResult' value in the case where the result was not being consumed. Once I added code to do something with the result, the problem went away (although I am still having problems get useful results from the 'trim' factory).

That's a huge issue to be aware of! Thanks again for sticking with me on this problem...
