Sample contents from components.xml, 


<framework:entity-query name="fundsQuery" ejbql="select f from Fund f" />
<framework:entity-home name="fundPerformanceHome" entity-class="xxx.entity.FundPerformance" />
<factory name="fundPerformance" value="#{fundPerformanceHome.instance}" scope="event"/>
...
...

I'm able to save an instance of FundPerformance but it's an empty row in the database. The only two fields populated are createdBy and createdDate which is a @PrePersist annotation in my entity class

What am I missing?

within the same environment setup, I'm able to invoke a SFSB seam component, action handler as well EJBQuery methods.

The initial problem was solved by wrapping the 

<h:form>

tag at the right place (it was displaced before). However, EntityHome now persists always with s primary key beginning with 1, irrespective of whether there is data present or not. I double checked the sequence (I have same sequence number for all the tables) using 


SELECT hibernate_sequence.NEXTVAL FROM dual;

,

the value was 21.

I'm generating the schema completely with hbm.ddl.auto and the default sequence generator is same for all the tables ( no max limit)

Any suggestions?

PS: If there is no data, it does work though.(with pk 1,2,3 etc ..)

Can you post the annotations you are using on the primary key field?

Cheers,

I dont have the code handy rt now, but it's something like this:- 

@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE)
private long id;

all our entity classes extend a BaseEntity class which has a version, id and some audit columns.

I've used similar annotations before, but using hibernate annotations. Didn't have a problem them. I'm guessing that running scripts (import.sql in classpath) via hbm.ddl.auto won't increment the sequence correctly.

I have tried with GenerationType.AUTO as well and I manually updated the sequence number in the database too, the problem persists -- it always saves with pk 1, to begin with.

Any help, appreciated.
