[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-1287) Enable support for DataModelSelection when used with entiy-query

[Gavin King (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBSEAM-1287?page=all ]

Gavin King closed JBSEAM-1287.
------------------------------

    Fix Version/s: 1.3.0.BETA1
       Resolution: Done
         Assignee: Gavin King

OK, suppose we have:

<h:dataTable value="#{customerQuery.dataModel}" var="customer"> 
   ...
</h:dataTable>

Did you try using:

@In("#{customerQuery.dataModel.rowData}")
Customer customer;

Or, in CVS, you can try the following:

@In("#{customerQuery.dataModelSelection}")
Customer customer;

Does that work for you?

> It would be nice to be able to match up a DataModelSelection with a DataModel that is provided by an entity-query.  As of now a deployment error is thrown.
> Use Case:  If a data table is driven by an entity-query, the only way currently to select a row is by passing the var using the Extended EL Seam provides.  The extended EL is not compatible with some component libraries (Trinidad) and it is very ugly to go through component bindings to get the current value of the selected row.  It would be nice to hook a DataModelSelection to the entity-query.
> Something like this
> -components.xml-
>   <framework:entity-query name="allUsers"
>                                ejbql="select u from User u"/>
> -facelets page-
> [code]
>             <tr:table id="user_table" value="#{allUsers}" var="user">
>                 <tr:column id="user_column">
>                     <f:facet name="header">
>                         <tr:outputText id="user_header" value="Customer"/>
>                     </f:facet>
>                     <tr:commandLink id="user_link" text="#{useruserName}" actionListener="#{attachUser.done}"/> 
>                 </tr:column>
>             </tr:table>[
> /code]
> -Seam Bean-
> @DataModelSelection("allUsers")
> List <User> userList;
