SYMPTOM:
When a user tries to open a metric editor of a new metric, the following error occurs in Strategy 9.x:
Out of stack space
Strategy will only validate the syntax of a single metric definition. Therefore, if a change in metric definition causes a circular reference in another metric, both metrics will still be validated independently. However, there are some instances while trying to resolve the metric definition where Strategy will enter an infinite loop until this error occurs. This will happen if the metric with the circular definition is inserted as a part of another metric definition. This will also occur if the metric is duplicated (through copy/paste) and the user attempts to enter the new metric editor.
ACTION:
Alter the definition of one of the offending metrics so that the circular definition is broken.
