Can't plot graphs for fields which where string type previously

[gsamat]

I can't phrase it in English properly, let me explain steps to reproduce the problem.

1. Write log stash config with a field without specifying :int or :float type, ingest some data with it to the elastic search
2. Change logstash config by adding :int or :float and start ingesting a lot of data
3. Create a histogram chart and filter query by time to show only newest events with :int or :float
4. Get ClassCastException Error in the histogram

+1 I am seeing this too. My colleague suggested waiting until tomorrow, as a new index will be created and it will then work... I've yet to verify this (I don't have a time machine), but even if it does work it seems somewhat unsatisfactory.

In Kibana 4 we require that all indices pointed to by an index pattern have matching field types. When that is not the case, the field type will be set to "conflict" and the application will tell you why you can't sort on it. Closing this as I consider it solved for now.
