[jboss-user] [JBoss Seam] - Tomahawk dataTable & NPE Problem

I use this: | <t:dataTable id="operationsTable" | rendered="#{ operations.rowCount > 0 }" | value="#{ operations }" | var="operation" | rowIndexVar="i" | sortColumn="#{ operationView.column }" | sortAscending="#{ operationView.ascending }" | headerClass="dataHeader" | rowClasses="dataLine1, dataLine2" | styleClass="dataTable"> | | <h:column> | <f:facet name="header"> | <h:commandLink action="#{ operationFiling.create }"> | <h:graphicImage url="/img/new.png"style="margin-left: 2px; margin-right: 10px;"/> | </h:commandLink> | </f:facet> | <h:outputText value="#{ i+1 }"/> | </h:column> | | <h:column> | <f:facet name="header"> | <t:commandSortHeader columnName="name" arrow="true"> | <h:outputText value="Nome"/> | </t:commandSortHeader> | </f:facet> | <s:link value="#{ operation[1] }" action="#{ operationFiling.open(operation[0]) }" styleClass="blue"/> | </h:column> | </t:dataTable> | Action: | @Stateful | @Name("operationView") | @Scope(ScopeType.SESSION) | public class OperationViewAction implements OperationView | { | | @In(create = true) | private QueryService queryService; | | @DataModel | private List<Object[]> operations; | | private String column; | | private boolean ascending; | | public String getColumn() | { | return column; | } | | public void setColumn(String column) | { | if (!column.equals(this.column)) sortOperations(); | this.column = column; | } | | public boolean isAscending() | { | return ascending; | } | | public void setAscending(boolean ascending) | { | if (ascending != this.ascending) sortOperations(); | this.ascending = ascending; | } | | | public String clean() | { | operations = null; | column = "name"; | ascending = false; | | return "operation"; | } | | | @Observer("updateOperationList") | public void loadOperations() | { | // fill operations list | // ... | | sortFidcOperations(); | } | | private void sortOperations() | { | if (operations == null) | return; | | Comparator<Object[]> comp = new Comparator<Object[]>() | { | | private RuleBasedCollator collator = (RuleBasedCollator) Collator.getInstance(new Locale("pt_BR")); | | public int compare(Object[] x, Object[] y) | { | if (ascending) | { | Object[] t = y; | y = x; | x = t; | } | if (column.equals("name")) | { | String x1 = (String) x[1]; | String y1 = (String) y[1]; | | if (x1 == null && y1 == null) return 0; | | if (x1 == null)
