Dynamic rich:datatable with el expression
Hello guys,
I'm creating a dynamic datatable (richfaces 3.3.3.Final) with a datascroller (in order to paginate the grid). But I couldn't get it work properly with EL Expression
I have a panel, inside then I have a dataScroller and a data table and all of this is inside another panel.
The main question is why does this not work?
Add a value expression as a value in a data table
table.setValueExpression("value", GeradorUtil.createValueExpression("#{geradorRelatorioManagerBean.listaPaginada}"));
CODES:
//PANEL
HtmlPanelGrid painel = new HtmlPanelGrid();
painel.setId( "datagridPanel" );
//TABLE
HtmlDataTable table = new HtmlDataTable();
table.setId("dataTableSomeId");
table.setVar("_lista");
table.setRows(10);
// >>>>>>>>>>>>>>>>>>>>> THIS IS NOT WORKING (the getListaPaginada() method code is below)<<<<<<<<<<<<<<<<<<<<<
table.setValueExpression("value", GeradorUtil.createValueExpression("#{geradorRelatorioManagerBean.listaPaginada}"));
table.getChildren().add( buildColuna("codigo", "Código", table.getVar()) );
table.getChildren().add( buildColuna("descricao", "Descrição", table.getVar()) );
//METHOD buildColuna
private UIComponent buildColuna(String varValue, String title, String var){
HtmlOutputText header = new HtmlOutputText();
header.setId( "id" + varValue + "Header" );
header.setValueExpression("value", GeradorUtil.createValueExpression( title ));
HtmlColumn coluna = new HtmlColumn();
coluna.setId( "Idcol" + varValue );
coluna.setHeader(header);
coluna.setStyleClass("font-normal");
HtmlOutputText txtColuna = new HtmlOutputText();
txtColuna.setId(par.getNome() + "tx" + varValue );
txtColuna.setValueExpression("value", GeradorUtil.createValueExpression("#{" + var + "." + varValue + "}") );
coluna.getChildren().add(txtColuna);
return coluna;
}
//SCROLLER
HtmlDatascroller scroll = new HtmlDatascroller();
scroll.setId("scroll");
scroll.setFor("dataTableSomeId");
scroll.setMaxPages(5);
scroll.setStepControls("hide");
scroll.setAlign("right");
scroll.setReRender( "datagridPanel" );
scroll.setRequestDelay(500);
scroll.setIgnoreDupResponses(true);
scroll.setEventsQueue( "scrollQueue");
//ADDing SCROLL and TABLE TO the Panel
painel.getChildren().add( scroll );
painel.getChildren().add( table );
//ObjetoComponenteDinamico
public class ObjetoComponenteDinamico {
String codigo
String descricao
//gets and sets and hash and equals methods
}
//METHOD getListaPaginada()
/**
* Metodo responsavel por implementar um {@link org.richfaces.model.DataProvider} que realizara a paginação sob demanda.
* @return ExtendedTableDataModel
*/
public ExtendedTableDataModel<ObjetoComponenteDinamico> getListaPaginada() {
lista = new ExtendedTableDataModel<ObjetoComponenteDinamico>(new DataProvider<ObjetoComponenteDinamico>() {
private static final long serialVersionUID = 1L;
@Override
public ObjetoComponenteDinamico getItemByKey(Object _CurrentHashCode) {
for (ObjetoComponenteDinamico obj : listaAuxiliar) {
if (obj.hashCode() == (Integer)_CurrentHashCode)
return obj;
}
return null;
}
@Override
public List<ObjetoComponenteDinamico> getItemsByRange(int firstRow, int endRow) {
PaginatedList<ObjetoComponenteDinamico> paginatedList = new PaginatedList<ObjetoComponenteDinamico>();
try {
paginatedList = new PaginatedList<ObjetoComponenteDinamico>(firstRow, endRow);
paginatedList.setSkipResults(firstRow);
paginatedList.setMaxResults(endRow);
listaAuxiliar = geradorEngine.listaPaginadaDinamica(consulta, paginatedList);
return listaAuxiliar;
} catch (GeradorEngineException e) {
jsfUtil.addMessageError("Nenhum registro encontrado.");
} catch (Exception e) {
jsfUtil.addMessageError(e.getMessage());
}
return null;
}
@Override
public Object getKey(ObjetoComponenteDinamico objetoComponenteDinamico) {
return objetoComponenteDinamico.hashCode();
}
@Override
public int getRowCount() {
try {
return geradorEngine.listaPaginadaDinamica(consulta, null).getTotalCount();
} catch (GeradorEngineException e) {
jsfUtil.addMessageError(e.getMessage());
} catch (Exception e) {
jsfUtil.addMessageError(e.getMessage());
}
return 0;
}
});
return lista;
}
The XHTML code is:
<!-- I have a method in my bean to bind this panel wich add the datatable above -->
<h:panelGrid id="renderPanel" binding="#{geradorRelatorioManagerBean.renderPanel}"/>
In order to test my methods I have the exactly same code in XHTML and is working fine
<h:panelGrid id="togglePanelLista">
<div align="right">
<rich:datascroller for="processosList" maxPages="5"
stepControls="hide"
reRender="togglePanelLista" align="right" requestDelay="500"
ignoreDupResponses="true" eventsQueue="fila" />
</div>
<rich:dataTable id="processosList"
value="#{geradorRelatorioManagerBean.listaPaginada}"
var="_processo"
rows="10"
onRowMouseOver="this.style.backgroundColor='#F1F1F1'"
onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'">
<rich:column>
<f:facet name="header">codigo</f:facet>
<h:outputText value="#{_processo.codigo}" styleClass="font-normal"/>
</rich:column>
<rich:column rendered="#{geradorRelatorioProcessamentoBean.podePararProcesso}">
<f:facet name="header">descricao</f:facet>
<h:outputText value="#{_processo.descricao}" styleClass="font-normal"/>
</rich:column>
</rich:dataTable>
</h:panelGrid>
When I run the dynamic code I get this error:
