[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-678) @NumericField does not work with BigDecimal types (and others?)

[G Fernandes (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-678?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=39816#action_39816 ] 

G Fernandes commented on HSEARCH-678:
-------------------------------------

Unfortunately, there's no support for encoding BigDecimal as a numeric fields in Lucene. Allowed types as int, long, float and double, and any other types than can be represented as one of those (Date as milliseconds, for example). I'll update the docs and work on the error message

> My first attempt to use BigDecimal ran into trouble trying to use the new @NumericField annotation.  The SessionFactory fails to create an instance of the session.  The code:
> {{
> @Column(name="val")
> @Field(name="val", index=Index.UN_TOKENIZED, store=Store.YES)
> @NumericField
> private BigDecimal val;
> }}
> Results in the exception:
> {{
> Exception in thread "main" java.lang.ExceptionInInitializerError
> [cut]
> Caused by: org.hibernate.HibernateException: could not init listeners
> [cut]
> Caused by: org.hibernate.search.SearchException: Unable to guess FieldBridge for val
> at org.hibernate.search.bridge.BridgeFactory.guessType(BridgeFactory.java:250)
> at org.hibernate.search.engine.AbstractDocumentBuilder.bindFieldAnnotation(AbstractDocumentBuilder.java:690)
> at org.hibernate.search.engine.AbstractDocumentBuilder.checkForField(AbstractDocumentBuilder.java:564)
> [cut]
> }}
> Taking out the @NumericField allows the session to start up successfully.
> I will attempt to make a test case but I'm having local build env issues.  'mvn clean install' of a fresh hibernate search git checkout is taking an incredibly long time (an hour for the first 10 or so .pom files?) so I may be several hours or days over this trivial task.
