Here's the session bean snippet...
| @Out(scope=ScopeType.SESSION)
| private DataModel openPackages = new ListDataModel();
|
| private String opQuery = "from PackageEntity p, OfficeEntity o where
p.office.id = o.id and p.code = 'OPN' and o.id = 1";
|
| @Create
| @Factory("openPackages")
| public void init() {
| openPackages.setWrappedData(em.createQuery(opQuery).getResultList());
| openPackages.addDataModelListener(this);
| openPackages.setRowIndex(0);
| }
|
the jsf snippet
| <h:dataTable value="#{openPackages}" var="pkgEntity"
rendered="#{openPackages.rowCount > 0}"
| rows="#{rowSize}" first="#{openIndex}"
rowClasses="evenRow,oddRow" cellspacing="0"
| onmouseover="highlightRow(event);"
onmouseout="unhighlightRow(event);">
| <h:column>
| <f:facet name="header">
| <h:outputText value="#{pkgHeaders.id}" />
| </f:facet>
| <h:commandLink value="#{pkgEntity.id}"
action="#{remittance.selectedRemittance}" />
| </h:column>
| <h:column>
|
| .... more columns ...
| </h:dataTable>

I believe I know what's wrong but I'm not sure why or how to fix it. So, if you
guys will bear with me and read along I'll explain as best I can.
I think the problem lies in the query which does a join and the resultant List actually
consists of both entity (PackageEntity and OfficeEntity) objects retreive from the
database (using hibernate). The reason I say this is because I had everything working just
fine with the simple query like so
from PacakgeEntity p where p.code = 'OPN'
This simple query returned a list of PackageEntity objects and all was good. The new query
returns a list alright, but it's not a PackageEntity list. It's an Object list.
Each element in the object list then contains a list of PackageEnity and OfficeEntity
objects that were created from the join (so I think).
So, it's seems that I have some sort of referencing problem and I don't really now
how to resolve it. Please ask if you need more information. This is hard to explain.
Thanks.
Eric Ray
