Problem with @OneToMany annotation with Spring Roo

Question

I'm trying to use Spring Roo to generate entities with a @OneToMany unidirectional relationship. Here's what I've tried:

entity --class ~.family.Child
field string --fieldName name
controller scaffold ~.web.ChildController
entity --class ~.family.Father
field string --fieldName name
field set --fieldName children --element ~.family.Child --cardinality ONE_TO_MANY 
controller scaffold ~.web.FatherController
perform package

This produces the expected entities and database tables (including a link table.) The Father entity is generated with the following annotation, which conforms to the JPA spec:

@OneToMany(cascade = CascadeType.ALL)
private Set<family.Child> message = new java.util.HashSet<family.Child>();

But when I go to the Roo-generated admin page, and click Create Father, I find the following message:

Create Father

Name:      (field to enter name)
Children:  This relationship is managed from the Father side.

This looks like a bug in Roo. Has anyone found a work-around? Or do I have an error in here?

Answer 1

OK, here's a workaround: In the fathers/create.jspx file, Roo generates the following line:

<field:simple field="children" id="c:family.Father.children" messageCode="entity.reference.not.managed" 
 messageCodeAttribute="Child" z="dMKrUOiCeYNub4vNayuiWJ99s1k="/>

This should be replaced by:

<field:select field="children" id="c:family.Father.children" itemValue="id" 
 items="${children}" multiple="true" path="/children"/>

And it should work.
