I am upgrading an index from Solr 3.6 to 4.2.0. Everything has been picked up except for the old DateFields.
I read some posts that due to the "extra functionality" of the TrieDateField you would need to re-index for those fields. To avoid re-indexing I was trying to do a Partial Update (http://solr.pl/en/2012/07/09/solr-4-0-partial-documents-update/), I am doing this with a Python script that does a query, pulls the field contents and then reformats it and sends a JSON update back to Solr. But no matter what I send Solr gives me the same error SEVERE: java.lang.ClassCastException: java.lang.String cannot be cast to java.util.Date at org.apache.solr.schema.TrieDateField.toObject(TrieDateField.java:70) at org.apache.solr.schema.TrieDateField.toObject(TrieDateField.java:55) …… I have tried send the date as a date string to be parsed and as a number of milliseconds from or before epoch. Both give the same error. Any suggestions would be appreciated. Examples of record attempts.
