Johannes Goll commented on SOLR-2295:
-------------------------------------
from Chris Hostetter
: I am getting a mal-formatted json response when using the
: stats component with a facet that returns a stddev value of NaN ,e.g
I'm not a JSON expert, but i suspect NaN just isn't legal JSON, and the
JSON response writer has a bug.
quick google search...
http://stackoverflow.com/questions/1423081/json-left-out-infinity-and-nan-json-status-in-ecmascript
...suggests that the only valid value is "null"
please file a bug.

> I am getting a mal-formatted json response when using the
> stats component with a facet that returns a stddev value of NaN ,e.g
> "facet-1":{
> "min":0.0604898,
> "max":0.0604898,
> "sum":1.209796,
> "count":20,
> "missing":0,
> "sumOfSquares":0.0731803180808,
> "mean":0.0604898,
> "stddev":NaN
> },
> I have submitted my complete response to
> http://jsonformatter.curiousconcept.com
> and got the following exception:
> Warning:Invalid quotes on string for the line with "stddev":NaN
> The Solr response broke my PHP code; replacing "NaN" with 0.0 solved the
> issue.
