SumRow rendered content before listener method fires

[rudy85]

Hi,
As per SumRow listener documentation
"Method expression to execute before rendering summary row. (e.g. to calculate totals)."

<p:summaryRow listener="#{rBean.setSortProperty}" >
<p:column colspan="#{rBean.sortSpan}" style="text-align:right">
<h:outputText value="Total:" />
</p:column>
<c:forEach items="#{rBean.sumRow}" var="sumcol" >
<p:column >
<h:outputText value="#{sumcol}">
<f:convertNumber maxFractionDigits="2" locale="ru_RU"/>
</h:outputText>
</p:column>
</c:forEach>

the bean

private List<BigDecimal> sumRow =new ArrayList<>(); // sum row val holder

public void setSortProperty(Object o) { // filter value
if (o instanceof String) {
setSortVal((String) o);
try {
sumRowCalc();
} catch (NoSuchMethodException ex) {
Logger.getLogger(rangeBean.class.getName()).log(Level.SEVERE, null, ex);
} catch (IllegalAccessException ex) {
Logger.getLogger(rangeBean.class.getName()).log(Level.SEVERE, null, ex);
} catch (IllegalArgumentException ex) {
Logger.getLogger(rangeBean.class.getName()).log(Level.SEVERE, null, ex);
} catch (InvocationTargetException ex) {
Logger.getLogger(rangeBean.class.getName()).log(Level.SEVERE, null, ex);
}
}
}

public void sumRowCalc() throws NoSuchMethodException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
sumRow.clear();
......

In my case inner column values rendered before setSortProperty fires, for ex. first time I click on sort column it shows empty sumrow, next time click it shows values from previous execution

ps

Please modify your post according to forum rules.Are you able to replicate the issue on showcase example.

Hi,
I added my environment details in initial post.
I replicated showcase with subtle modifications as follows

<h:form>
<p:dataTable var="car" value="#{dtSummaryRowView.cars}" >

<p:ajax event="sort" listener="#{dtSummaryRowView.onsort}" id="sortev" async="true" >
<f:attribute name="event" value="event" />
</p:ajax>

<p:column headerText="Id" sortBy="#{car.id}">
<h:outputText value="#{car.id}" />
</p:column>
<p:column headerText="Year" sortBy="#{car.year}">
<h:outputText value="#{car.year}" />
</p:column>
<p:column headerText="Brand" sortBy="#{car.brand}">
<h:outputText value="#{car.brand}" />
</p:column>
<p:column headerText="Color" sortBy="#{car.color}">
<h:outputText value="#{car.color}" />
</p:column>
<p:summaryRow listener="#{dtSummaryRowView.setSortProperty}">
<p:column colspan="3" style="text-align:right">
<h:outputText value="Total:" />
</p:column>
<c:forEach items="#{dtSummaryRowView.randomPrice}" var="sumcol" >
<p:column>
<h:outputText value="#{sumcol}">
</h:outputText>
</p:column>
</c:forEach>
</p:summaryRow>
</p:dataTable>
</h:form>


the bean

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.enterprise.context.ApplicationScoped;
import javax.inject.Named;
import org.primefaces.event.data.SortEvent;
import service.Car;

@ApplicationScoped
@Named("dtSummaryRowView")
public class SummaryRowView implements Serializable {

private List<Car> cars;

//@ManagedProperty("CarService")
private CarService service=new CarService();

private List<String> testFire = new ArrayList<>();


@PostConstruct
public void init() {
cars = service.createCars(50);
testFire.add("I'm not initialized!");
}

public List<Car> getCars() {
return cars;
}

public void setService(CarService service) {
this.service = service;
}

public List<String> getRandomPrice() {
return testFire;
//return (int) (Math.random() * 100000);
}

public void setSortProperty(Object o) { // filter value
if (o instanceof String) {
testFire.add("set sort: "+(String)o);
}
}

public void onsort(SortEvent event) { //filter by
if(event!=null){
testFire.add("get column: "+(String)event.getSortColumn().getHeaderText()+" I'm Initialized");
}
}
}

So, first time table rendered not calling listener method setSortProperty, this is an issue.
