Possible Bug in the 2.0.0 webclient

When downloading the packed server version of Neo4j community v2.0.0, they provide a web interface for Cypher, however, I cannot make it accept queries of the form:

MATCH (a:Person {name: {value1}})
RETURN a;

It calls a syntax error on the first curly bracket, and will only accept 

MATCH (a:Person)
WHERE a.name ="value1"
RETURN a;

Am I using it wrong, or is this a bug in the parser? The first form appears to work fine when you use it with an embedded client, it is only when using the webclient interface that there is a problem.

UPDATE: To be clear, in the 2.0.0 web interface, even the examples from the Cypher 2.0 reference card throw syntax errors; e.g. the line MATCH (n {name:'Alice'})-->(m) RETURN n from the reference card: http://docs.neo4j.org/refcard/2.0/ gives the following error:

Node properties cannot be specified in this context (line 1, column 10)
"MATCH (n {name:'Alice'})-->(m)"

even though it works fine when passed to the cypher execution engine in the embedded client.

ANSWER: It turned out the problem was that I was using a milestone release which was not complete/bug free. 2.0.1 stable release solves this problem.

The notation of your first query is using parameterized Cypher, see http://docs.neo4j.org/chunked/stable/cypher-parameters.html. Parameters are important when developing an application using Neo4j. For usage inside the Neo4j browser, parameters are pretty much useless as you cannot specify the values.

Use the following syntax instead:

MATCH (a:Person {name: 'value1'})
RETURN a;
