Re: Problems changing from rc4 to rc5

[Armin Waibel]

Hi Dean,

in rc4 "empty cache" implementation use a temporary map to prevent 
circular references. You can use ObjectCachePerBrokerImpl to prevent 
circular references (this implementation is very similar to the old 
version of empty cache)

regards,
Armin

I have found my problem after reading the FAQ.  I had circular
references in our model and we were using EmptyCache; however in RC4 we
did not run into the problem with infinite loading of objects.

Subject: Problems changing from rc4 to rc5

I have recently switched from rc4 to rc5 and I am having problems
retrieving a collection of client groups from my class client (shown
below).  The class client-group uses an anonymous reference to the
client class but it appears that every time I try to retrieve the
client, it retrieves the client group, then the client groups class
retrieves the client and I enter into an infinite loop of retrieving
client, client group, client....
I am using the Persistence Broker API, and I have not changed my
repository-user.xml file from rc4. 

<class-descriptor
          class="com.lmig.pm.affinity.model.client.Client"
          table="DEXA010T"
      <field-descriptor
         name="id"
         column="CLIENT_ID"
         jdbc-type="VARCHAR"
         primarykey="true"
         autoincrement="false"
      />
      <field-descriptor
         name="wipStatusId"
         column="WIP_STATUS_ID"
         jdbc-type="INTEGER"
         access="anonymous"
      />
      <reference-descriptor name="wipStatus" 
           class-ref="com.lmig.pm.affinity.model.client.WipStatus">
      	<foreignkey field-ref="wipStatusId"/>
      </reference-descriptor>

	<collection-descriptor
      	name="clientGroups"
 
element-class-ref="com.lmig.pm.affinity.model.client.ClientGroup"
      	auto-delete="true"
      >
      		<inverse-foreignkey field-ref="clientId" />
      </collection-descriptor>
</class-descriptor>

<class-descriptor
   	  class="com.lmig.pm.affinity.model.client.ClientGroup"
   	  table="DEXA020T"
   	  
   >
      <field-descriptor
         name="id"
         column="CLIENT_GROUP_ID"
         jdbc-type="INTEGER"
         primarykey="true"
         autoincrement="true"
         access="readonly"
      />
      
      <field-descriptor
         name="clientId"
         column="CLIENT_ID"
         jdbc-type="VARCHAR"
         access="anonymous"
      />
      <reference-descriptor name="client"
class-ref="com.lmig.pm.affinity.model.client.Client">
      	<foreignkey field-ref="clientId"/>
      </reference-descriptor>

</class-descriptor>

If anyone has any suggestions on what I might be doing wrong please let
me know.
Thanks

Dean
