Neo4J: Query parameters conversion not working

[vmarcinko]

Hi,

I dunno if this is a bug, or it is intended to be so, but when I pass some parameter into query method that has custom class-to-String conversion registered, the query method does not convert the value to String.

Concretely, I use:

neo4jTemplate.query(cypherQueryString, queryParametersMap)

And I have Joda DateTime-to-String converters registered through ConversionService. Mapping to entity fields works fine with these converters (unfortunately not to Long values, only String, but I already registered that bug).

Anyway, when I put something like this inside my query parameters map:

queryParametersMap.put("time", new DateTime());

the query return no result, which is not correct.
But when I call conversion manually, like:

queryParametersMap.put("time", neo4jTemplate.convert(new DateTime(), String.class));

then the query returns the result.

It's as if query method ignores the registered custom conversion for query parameters.

Is this a bug?

It is difficult to determine for parameters which property/type they refer to, so in principle the only thing we can do is to look for spring converters.

Can you raise a JIRA issue for this?

Thanks a lot
