hello people

,

I'm a new user of primefaces and I'm trying to make a datable with a delete button like a commandButton with Ajax feature. I used the primefaces show case to test the table and the Datatable don't rerender after i click on delete button.

my datatable code in datatableLzy.xhtml :

Code: Select all

                <p:dataTable id="lazyTableCar" widgetVar="lazyTableCarWidget"
                             var="car" value="#{tableBean.lazyModel}" paginator="true" rows="10" lazy="true"
                             paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink}"
                             rowsPerPageTemplate="5,10,15"
                             selection="#{tableBean.selectedCar}" selectionMode="single"
                             onRowSelectComplete="carDialog.show()" onRowSelectUpdate="display">

                    <f:facet name="header">
                        Displaying #{tableBean.countLazyCars} Cars
                    </f:facet>

                    <p:column headerText="Model">
                        <h:outputText value="#{car.model}" />
                    </p:column>

                    <p:column headerText="Year">
                        <h:outputText value="#{car.year}" />
                    </p:column>

                    <p:column headerText="Manufacturer">
                        <h:outputText value="#{car.manufacturer}" />
                    </p:column>

                    <p:column headerText="Color">
                        <h:outputText value="#{car.color}" />
                    </p:column>

                    <p:column >
                        <p:commandButton value="Delete"  action="#{tableBean.delete}" update="lazyTableCar" >
                            <f:setPropertyActionListener value="#{car}" target="#{tableBean.selectedCar}" />
                        </p:commandButton>
                    </p:column>

                </p:dataTable>

my code in TableBean.java

Code: Select all


    private List<Car> lazyCars;

    private int countLazyCars;

	public TableBean() {
		cars = new ArrayList<Car>();
		carsSmall = new ArrayList<Car>();
        carsLarge = new ArrayList<Car>();
        droppedCars = new ArrayList<Car>();
		
		populateRandomCars(cars, 50);
		populateRandomCars(carsSmall, 9);
        populateRandomCars(carsLarge, 200);
        populateRandomSales();

        createDynamicColumns();
        populateDynamicCars();
        manufacturerOptions = createFilterOptions(manufacturers);
        	
		lazyModel = new LazyDataModel<Car>() {

			/**
			 * Dummy implementation of loading a certain segment of data.
			 * In a real application, this method should load data from a datasource
			 */
			@Override
			public List<Car> load(int first, int pageSize, String sortField, boolean sortOrder, Map<String,String> filters) {
				logger.log(Level.INFO, "Loading the lazy car data between {0} and {1}", new Object[]{first, (first+pageSize)});

                //Sorting and Filtering information are not used for demo purposes just random dummy data is returned
				
												
				return loadLazyCars(first, pageSize);
			}
		};

        /**
         * In a real application, this number should be resolved by a projection query
         */

        lazyModel.setRowCount(100);
        countLazyCars=100;
        lazyCars = new ArrayList<Car>();
	populateLazyRandomCars(lazyCars, 100);

	}

        public List<Car> loadLazyCars(int first, int pageSize){
            List<Car> result = new ArrayList<Car>();

            for (int i = first; i < (first + pageSize); i++) {
                result.add(lazyCars.get(i));
            }

            return result;
        }

      public String delete() {
         lazyCars.remove(selectedCar);
         lazyModel.setRowCount(lazyCars.size());
         return null;  
     }

    public int getCountLazyCars() {
        return countLazyCars;
    }

    public void setCountLazyCars(int countLazyCars) {
        this.countLazyCars = countLazyCars;
    }

I tried use "onComplete" evente in button to call JavaScript function to reload rows in datatable and don't work.

Code: Select all

<p:commandButton value="Delete"  action="#{tableBean.delete}" update="lazyTableCar" oncomplete="lazyTableCarWidget.loadLiveRows">
                            <f:setPropertyActionListener value="#{car}" target="#{tableBean.selectedCar}" />
</p:commandButton>

I'm using the newest versions of prime-showcase and primefaces-2.2-snapshot.

its does rerender, thou theres glitch in event firing

anything you do parameter ur passing go after all ajax bound to button well just something but try this

ditch action and f:set shit and add somthing like this

Code: Select all

actionListener="#{tableBean.deleteCar(car)}"

heres my code what works

Code: Select all

							<p:commandLink oncomplete="showDlg.show();" actionListener="#{galBean.setShowItem(item)}" update="showPanel">
								<p:graphicImage value="#{item.thumbPath}" cache="false"/><br/>
								<h:outputText value="#{item.displayLink}" />
							</p:commandLink>

I did what you sugest but the datatable still don't rerender. the "car" was deleted form list but the datatable don't rerender. After i delete the "car" and change the page of datatable and back to first page finanlly the car is deleted from datatable

my chande code:

xhtml:

Code: Select all

                    <p:column >
                        <p:commandButton value="Delete"  actionListener="#{tableBean.delete(car)}" update="lazyTableCar" />
                            
                        <p:commandButton value="Delete"  action="#{tableBean.delete(car)}" update="lazyTableCar" />

                        <p:commandLink value="Delete" actionListener="#{tableBean.delete(car)}" update="lazyTableCar"/>

                        <p:commandLink value="Delete" action="#{tableBean.delete(car)}" update="lazyTableCar"/>

                    </p:column>

tableBean

Code: Select all

      public String delete(Car car) {
         lazyCars.remove(car);
         lazyModel.setRowCount(lazyCars.size());
         return null;  
     }

thanks for you help.

aah lazy do following

public void refreshTable() {
DataTable dataTable = (DataTable) FacesContext.getCurrentInstance().getViewRoot().findComponent("txForm:txTable");
dataTable.loadLazyData();
}

I did what you sugest and datatable still don't rerender, please see my code.

Code: Select all

      public String delete(Car car) {
         lazyCars.remove(car);
         lazyModel.setRowCount(lazyCars.size());
         refreshTable();
         return null;  
     }

    public void refreshTable() {
        DataTable dataTableTest = (DataTable) FacesContext.getCurrentInstance().getViewRoot().findComponent("myForm:lazyTableCar");
        dataTableTest.loadLazyData();
    }

I debug the code, and the car are deleted from list, the refreshTable method is called, method load of LazyDataModel<Car> is called, all fine. But the table in browser isn't refreshed.

was dataTableTest found?

Posted: **26 Jan 2011, 21:29**

yes, was found. Worked all fine. dataTableTest != null, the method load was called.

have you tried

Code: Select all

<p:commandButton value="Delete"  actionListener="#{tableBean.delete(car)}" update="@form" />

or

Code: Select all

<p:commandButton value="Delete"  actionListener="#{tableBean.delete(car)}" update="myForm:lazyTableCar" />

?

Posted: **27 Jan 2011, 15:52**

It's Works! Thanks a lot brothers, the code that works:

Code: Select all

<p:commandButton value="Delete"  actionListener="#{tableBean.delete(car)}" update="@form" />

I will clear all my code and post here the final solution.
