Description

It would be quite useful if the following contained techTag.toString():

FreeMarker template error (DEBUG mode; use RETHROW in production!):
The following has evaluated to null or missing:
==> techTag.title [in template "reports/templates/techReport-boxes.ftl" at line 133, column 59]

Java stack trace (for programmers):

---

freemarker.core.InvalidReferenceException: [... Exception message was already printed; see it above ...]
at freemarker.core.InvalidReferenceException.getInstance(InvalidReferenceException.java:134)
at freemarker.core.EvalUtil.coerceModelToTextualCommon(EvalUtil.java:465)

Now as it doesn't, I need to write a logging line, rebuild the project, and run again. Or debug. Neither is quick So this would save quite some time in development cycle.

Thanks for considering.
