I've encountered a couple problems trying to use the LIKE operator.

1) It doesn't work when the pattern is a query parameter. The error happened with it tried to cast a Neo4jQueryParameter to a String on the last line of Neo4jQueryRendererDelegate.predicateLike(). I no longer have the exception trace for that though.

2) The ESCAPE clause doesn't seem to work - after the core Hibernate code parses the query successfully, I get the following exception:

Caused by: org.hibernate.hql.ParsingException: HQL000002: The query SELECT e FROM com.nokia.nspos.model.domain.mock.entities.MockEntity e WHERE (mockString LIKE 'i' ESCAPE '\') is not valid; Parser error messages: [[statement, statementElement, selectStatement, queryExpression, querySpec, whereClause, logicalExpression, expression, logicalOrExpression, logicalAndExpression, negatedExpression, equalityExpression, relationalExpression, concatenation, additiveExpression, multiplyExpression, unaryExpression, atom, expressionOrVector, expression, logicalOrExpression, logicalAndExpression, negatedExpression, equalityExpression, relationalExpression, likeEscape, concatenation, additiveExpression, multiplyExpression, unaryExpression]: line 1:108 state 0 (decision=68) no viable alt; token=[@35,108:108='<EOF>',<-1>,1:108], [statement, statementElement, selectStatement, queryExpression, querySpec, whereClause, logicalExpression, expression, logicalOrExpression, logicalAndExpression, negatedExpression, equalityExpression, relationalExpression, concatenation, additiveExpression, multiplyExpression, unaryExpression, atom]: line 1:108 mismatched token: [@35,108:108='<EOF>',<-1>,1:108]; expecting type RIGHT_PAREN].

Sorry about the double post. Network problems, I think. Feel free to delete this one if you can.
