Bean method not being invoked

StackOverflow https://stackoverflow.com/questions/23550003

Question

Turns out that faces-config.xml was overriding the inline annotation ViewScoped in my Controller class w/ RequestScoped. Fixed it and that seem to solve the problem.

This question does not have an answer here commandButton/commandLink/ajax action/listener method not invoked or input value not updated and if you think it does, please provide a working fix/example using primefaces fluidGrid extension.

I am using primefaces ui exension fluidGrid : http://fractalsoft.net/primeext-showcase-mojarra/sections/fluidgrid/dynamic.jsf

I can't seem to invoke profileController.testControl() , if I place the commandButton outside of the fluidGrid it works fine , but not within the grid. Any ideas?

I've tested by changing my bean to @ViewScoped , there are no nested forms etc.

           <!-- another button attempt that doesn't work -->

//Tried with  @ViewScoped as well
@Model
public class ProfileController {
    public void testControl(){
        log.info("---------------------------------------");
        log.info("TEST CONTROL CLICKED");
        log.info("---------------------------------------");
    }

    public void testControlEvent(ActionEvent actionEvent){
        log.info("---------------------------------------");
        log.info("TEST CONTROL CLICKED");
        log.info("---------------------------------------");
    }
}
Was it helpful?

Solution

I've tried the simple example of having command button inside fluidGrid and it works here.

ManagedBean code

package bean;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;

import org.primefaces.extensions.model.fluidgrid.FluidGridItem;

@ManagedBean(name = "tBean")
@ViewScoped
public class TestBean implements Serializable{

    private List<FluidGridItem> images;

    @PostConstruct
    protected void initialize() {
        images = new ArrayList<FluidGridItem>();

        for (int j = 0; j < 3; j++) {
            for (int i = 1; i <= 10; i++) {
                images.add(new FluidGridItem("i" + 1));
            }
        }
    }

    public void doAction() {

        System.out.println("Im doing action");
    }

    public List<FluidGridItem> getImages() {
        return images;
    }
}

Try above and see if that works for you. If it works then try to use in your implementation.

OTHER TIPS

I have sometimes problem with rendered and button not being invoked. Make sure that your rendered="#{!showvar.isSeries()}" works correct or remove it and try again.

u must update your form i think in your page add in the button update=":form1:fluidGrid" if dosent work make the ajax on true it helped to solve a problem like this i hope it will help you
