Delete comments doesn't work with PostgreSQL

[MPriess]

Hi,

if I try to delete a comment I get the exception below. Actually I'm using Activiti 5.13, PostgreSQL 9.2 and postgresql_9.2-1002.jdbc4 as driver.

org.apache.ibatis.exceptions.PersistenceException:
### Error querying database.  Cause: org.postgresql.util.PSQLException: Unzulõssiger Wert f³r den Typ long : \x48616c6c6f.
### The error may exist in org/activiti/db/mapping/entity/Comment.xml
### The error may involve org.activiti.engine.impl.persistence.entity.CommentEntity.selectComment-Inline
### The error occurred while setting parameters
### SQL: select *      from ACT_HI_COMMENT      where ID_ = ?
### Cause: org.postgresql.util.PSQLException: Unzulõssiger Wert f³r den Typ long : \x48616c6c6f.
