Non-descript Builder error results in huge amount of time tracking down the problem
Please see the attached custom indicator (MyMA.java), which I have used in a simple Strategy Template with a single Random Group. For some reason this is throwing an error upon using it. I'm still troubleshooting what the issue is. However, the Builder does not indicate anything that really helps me pinpoint either the Random Group involved, or the customer indicator involved (MyMA()). I had to deconstruct a far more complicated strategy template line by line to ultimately get to the bottom of it. Each time this kind of error happens, it's many hours spent on the debug. Would be great if the Builder's error message gave the information necessary to quickly pinpoint the problem.
