8:31 a.m.
This is my first attempt at using parts of the CRUD framework. I am getting an exception
when trying to access the results of an entity query.
Here is the query defined in components.xml
<framework:entity-query name="allCustomers"
| ejbql="select u from User u"/>
I am trying to use this as a part of the Trinidad Dialog framework but I don't think
the problem is tied to Trinidad since the same exception occurs when I try to place my
dataTable that shows the results from the query inline with my main page.
Here is how I am using the query
<tr:table value="#{allCustomers.resultList}"
var="customer">
| <tr:column>
| <f:facet name="header">
| <tr:outputText value="Customer"/>
| </f:facet>
| <tr:commandLink text="#{customer.userName}"
action="#{attachCustomer.select}"/>
| </tr:column>
| </tr:table>
Here is the exception
