[JBoss Seam] - Re: DataTable Sorting Example
by griffitm
Ok, I tried restructuring this as a framework query, and the query works, but the pagination throws an exception.
First the query as defined in components.xml:
<framework:entity-query name="deliverableSearchList"
| entity-manager="#{em}"
| ejbql="select d from Deliverable d"
| order="d.dueDate">
| <framework:restrictions>
| <value>d.dueDate > #{search.fromDate}</value>
| <value>d.dueDate < #{search.toDate}</value>
| </framework:restrictions>
| </framework:entity-query>
|
And My XHTML:

|
| <div class="tableControl">

| value="#{messages.left}#{messages.left} First Page"
| id="firstPage">

| </s:link>
|
| <s:link view="/Search.xhtml"

| </s:button>
| </s:div>
|
| </ui:define>
|
| </ui:composition>
|
And my managed Bean:
| @Name("search")
| @Scope(ScopeType.SESSION)
| public class Search {
|
| /** Creates a new instance of Search */
| public Search() {
|
| }
| private Date fromDate;
| private Date toDate;
|
| public Date getFromDate() {
| if(fromDate == null){
| fromDate= Calendar.getInstance().getTime();
| }
| return fromDate;
| }
|
| public void setFromDate(Date fromDate) {
| this.fromDate = fromDate;
| }
|
| public Date getToDate() {
| if(toDate == null){
| Calendar calendar= Calendar.getInstance();
| calendar.roll(Calendar.DAY_OF_YEAR, 30);
| toDate= calendar.getTime();
| }
| return toDate;
| }
|
| public void setToDate(Date toDate) {
| this.toDate = toDate;
| }
|
|
| }
|
Throws Exception:
| javax.faces.FacesException: javax.el.ELException: /Search.xhtml @162,33 rendered="#{deliverableSearchList.nextExists}":
| Error reading 'nextExists' on type org.jboss.seam.framework.EntityQuery_$$_javassist_9
| at javax.faces.component.UIComponentBase.isRendered(UIComponentBase.java:373)
| at javax.faces.component.UIComponent.encodeAll(UIComponent.java:880)
|
If I remove the pagination, the search works fine. How is this any different from the managed components generated by seam gen?
Any help would be much appreciated!
Best Regards,
MG
