Seam 1.1 & Tomahawk Datatable

newlukai Nov 29, 2006 4:15 AM

Hi,

I'm trying to migrate to Seam 1.1 and having some problems. I hope that somebody can help.

On several pages in my application I make use of the DataModelWithTomahawkDataTable workaround mentioned on the wiki (http://wiki.jboss.org/wiki/Wiki.jsp?page=DataModelWithTomahawkDataTable).
Since I use Seam 1.1 this workaround doesn't work anymore. Or I made a mistake.

The workaround proposes to annotate a method as @Factory("xyz") for a member and to annotate the corresponding getter with @DataModel. So when I use "xyz" on a page there are two methods related to the attribute. In the past the @DataModel was invoked, but now it seems that the @Factory is invoked. That's fatal since the @Factory returns String (in the wiki it returns void) so all the subsequent calls to the "var" of the dataTable are invoked on the String.

That's one problem. The other problem also has to do with this workaround and I hope it will disappear when the first problem is fixed.
There has to be something wrong with the column member which is introduced to make a dataTable sortable, but I don't know what's wrong with it at all. And there's only a stack-trace which doesn't tell me anything useful. Perhaps somebody else knows what's the problem:

Could U show some code?

Sure. Here we go:

The session bean:

@Stateful
@Scope(ScopeType.SESSION)
@LoggedIn
@Name("searchTestaction")
public class SearchTestactionAction implements Serializable, SearchTestaction {
 @PersistenceContext(unitName = "aresDatabase")
 private transient EntityManager em;

 @In(required=false)
 private Testaction testaction;

 private List<Testaction> foundTestactions;
 @DataModelSelection
 @Out(required=false, scope=ScopeType.SESSION)
 private Testaction foundTestaction;
 //@DataModelSelectionIndex workaround
 private int foundTestactionIndex;

 @In(required=false)
 private Release selectedRelease;

 private String sortColumn = "id";
 private boolean ascending = true;

 @Factory("foundTestactions")
 public String search() {
 //omitted: generate the query

 if(query.length() != 0) {
 if(selectedRelease != null) {
 addPrefix(query);
 query.append("TACT_REL_ID=");
 query.append(selectedRelease.getID());
 }
 foundTestactions = EMHelper.execQuery(em, "from Testaction " + query.toString() + " order by TACT_ID asc");
 Collections.sort(foundTestactions, new TestactionComparator(sortColumn, ascending));
 }

 return "search";
 }

 @DataModel
 public List<Testaction> getFoundTestactions() {
 return foundTestactions;
 }

The page with a search form and a result list:

<ui:define name="content">
 <h1>#{ares_messages.header_searchTestaction}</h1>
 <h:form>
 <div id="errors"><h:messages layout="table" /></div>
 <div class="buttonLine">
 <h:outputText rendered="#{not empty searchTestaction.foundTestactions}"
 value="#{ares_messages.label_search_displaySearchForm}"
 onclick="switchVisibility('searchForm'); this.style.display='none';" styleClass="button"
 style="margin-right: 30px; padding: 5px; cursor: pointer;" />
 <h:commandButton action="#{searchTestaction.search}" image="img/find.gif" styleClass="graphical"
 style="margin-left: 0px; margin-right: 15px;" title="#{ares_messages.tooltip_searchTestaction}" />
 </div>

 <div id="release">
 <h:outputText value="#{ares_messages.filter_release}: " />
 <h:selectOneMenu value="#{releaseSelector.selectedReleaseNumber}">
 <f:selectItems value="#{releaseSelector.releaseItems}" />
 </h:selectOneMenu>
 </div>

 <div id="searchForm" style="display: #{empty searchTestaction.foundTestactions ? 'block' : 'none'};">

....


<t:dataTable var="testaction_var"
 value="#{foundTestactions}"
 id="foundTestactionsTable"
 renderedIfEmpty="false"
 sortColumn="#{searchTestaction.sortColumn}"
 sortAscending="#{searchTestaction.ascending}"
 preserveSort="true"
 rows="20">
 <f:facet name="header">
 <h:outputText value="#{ares_messages.label_ResultCount}: #{foundTestactions.rowCount}" />
 </f:facet>

This ocde adresses the first problem I mentioned. The second problem occurs here:

Bean:

@Stateful
@Scope(ScopeType.SESSION)
@LoggedIn
@Name("testactionValidator")
public class TestactionValidatorAction extends TestactionHandling implements Serializable, TestactionValidator {
 @In(required=false)
 private Release selectedRelease;

 @In(required=false)
 private User selectedUser;

 private Long lastSelectedReleaseID;
 private String lastSelectedUserID;

 @Factory("testactionsForValidator")
 public void initTestactions() {
 if(hasAFilterChanged() || shouldRefresh() || testactions == null) {
 StringBuffer filter = new StringBuffer();
 if(selectedRelease != null) {
 filter.append(" and TACT_REL_ID=");
 filter.append(selectedRelease.getID());
 }
 testactions = EMHelper.execQuery(em.createQuery(
 "from Testaction where TACT_VALIDATOR_USR_ID=:validator and " +
 "TACT_BFV_ID=" + BugfixValidation.Constants.TO_VALIDATE.value() + " and " +
 "TACT_REV_ID!=" + Revisionclass.Constants.TO_BUGFIX.value() +
 filter.toString() +
 " order by TACT_ID asc"
 ).setParameter("validator", user.getIsAdmin().equals(new Integer(-1)) ? selectedUser.getID() : user.getID()));

 lastSelectedReleaseID = (selectedRelease == null) ? null : selectedRelease.getID();
 lastSelectedUserID = (selectedUser == null) ? null : selectedUser.getID();
 }
 Collections.sort(testactions, new TestactionComparator(column, ascending));
 }

 @DataModel(scope=ScopeType.PAGE)
 public List<Testaction> getTestactionsForValidator() {
 initTestactions();
 return testactions;
 }

And the page:

<t:dataTable var="testaction_var" value="#{testactionsForValidator}"
 renderedIfEmpty="false" sortColumn="#{testactionValidator.column}"
 sortAscending="#{testactionValidator.ascending}" preserveSort="true">
 <f:facet name="header">
 <h:outputText value="#{ares_messages.label_ResultCount}: #{testactionsForValidator.rowCount}" />
 </f:facet>
 <h:column>
 <f:facet name="header">
 <t:commandSortHeader columnName="id">
 <h:outputText value="#{ares_messages.label_testaction_ID}" />
 </t:commandSortHeader>
 </f:facet>
 <h:commandLink value="#{testaction_var.ID}"
 action="#{testactionValidator.select}" styleClass="rightAlignment" />
 </h:column>

The members "column" and "ascending" are defined in the superclass (with getters and setters). Perhaps that's is the problem?
