OCM Collection Question
Hello,
I am VERY new to Jackrabbit (today) and am trying to get my collection to
save how I want, but not having any luck. Any help would be greatly
appreciated.
I have a "CommentList" object that has a java.util.List of "AuthoredText"
objects. AuthoredText has a creationDate field. Each time a user adds a
new AuthoredText object to a CommentList, I save the entire CommentList
using ocm.update or ocm.insert if the CommentList is new. Doing the
ocm.update appears to resave all of AuthoredText objects previously saved in
the CommentList instead of just the newly created one, resetting the
creationDates on all of them. Is there any way I can save the new
AuthoredText directly or at least have the others not updated when I save
the master CommentList object?
Here are some relavant pieces of info....
*Some mapping info....*
<class-descriptor
className="com.hyper9.service.workspace.ocm.CommentList"
jcrType="h9:commentList"
extend="com.hyper9.service.resource.ocm.HierarchyNode" >
<collection-descriptor fieldName="comments" proxy="true"
jcrType="h9:authoredText" jcrElementName="h9:comment"
elementClassName="com.hyper9.service.resource.ocm.AuthoredText"
jcrSameNameSiblings="true"
collectionConverter="org.apache.jackrabbit.ocm.manager.collectionconverter.impl.NTCollectionConverterImpl"
/>
</class-descriptor>
<class-descriptor
className="com.hyper9.service.resource.ocm.AuthoredText"
jcrType="h9:authoredText"
extend="com.hyper9.service.resource.ocm.AbstractResourceObject">
<field-descriptor fieldName="author" jcrName="h9:author" />
<field-descriptor fieldName="text" jcrName="h9:text" />
</class-descriptor>
<class-descriptor
className="com.hyper9.service.resource.ocm.AbstractResourceObject"
abstract="true">
<field-descriptor fieldName="path" path="true" />
<field-descriptor fieldName="creationDate" jcrType="Date"
jcrName="jcr:created" jcrProtected="true"
jcrAutoCreated="true" />
</class-descriptor>
*Some NodeType info...*
<nodeType name="h9:commentList">
<supertypes>
<supertype>h9:hierarchyNode</supertype>
</supertypes>
<childNodeDefinition name="h9:comment" autoCreated="false"
defaultPrimaryType="h9:authoredText"
mandatory="false" onParentVersion="COPY" protected="false"
sameNameSiblings="true">
<requiredPrimaryTypes>
<requiredPrimaryType>h9:authoredText</requiredPrimaryType>
</requiredPrimaryTypes>
</childNodeDefinition>
</nodeType>
<nodeType name="h9:authoredText">
<supertypes>
<supertype>nt:hierarchyNode</supertype>
</supertypes>
<propertyDefinition name="h9:text" requiredType="String"
autoCreated="false" mandatory="true"
onParentVersion="COPY" protected="false" multiple="false" />
<propertyDefinition name="h9:author" requiredType="String"
autoCreated="false" mandatory="true"
onParentVersion="COPY" protected="false" multiple="false" />
</nodeType>
Thanks!
Ryan

I think I figured it out. I had tried setting the path of the child object
directly but it wasn't working. The reason was because the wrapper I was
using for the save was checking if the path existed and only did an insert
if it didn't exist. In a SNS this doesn't work because even though the path
existed I still want to do an insert.
