Hy all,

i am new with all of this,and probably this would be a dumb question,but

i have an managed bean that has a property flower - String, and a property List - bouquet

in a xhtml i have an h:inputText in witch you should type a flower name and when you click a h:command button it callas an action #{managedBEan.addFlower}, in addFlower i want to add the flower name typed by the user and added in list --- i am using a h:form

but it seems that the set method for property aren't called by jsf when i click the button, the flower property have null as value, like she was declared

thank you for your sugestions, Alex

Bean:

... myBean() {
   Flower flower;

   (...)

   public void addFlower() { }

   //getters and setters for Flower prop.
}

Xhtml

<h:inputText value="#{myBean.flower.name}"/>
<h:commandButton action="#{myBean.addFlower}" value="Click me!"/>

Thats all you have to do. A instance for flower with get and set and a h:inputText with the flower name in "value" property.

When you clicks the button, the value typed will be put in the property referenced in value, so if you print the flower.name (in addFlower method) you will be able to see the user input.

actionListener works too, but you need to check wich import you are using for ActionEvent. IDE always import java.awt.event.ActionEvent but the right one is javax.faces.event.ActionEvent... java.awt doesn't work and I guess thats why your method is not called.

You have to declare an actionListener, like this:

<h:commandButton actionListener="#{myBean.addFlower}" . . .

and in your bean you must define addFlower 

   public void addFlower(ActionEvent ev)

that execute the job.

Does an tag surround both, the input and the button?

<h:form>
    <h:inputText value="#{myBean.flower.name}"/>
    <h:commandButton action="#{myBean.addFlower}" value="Click me!"/>
</h:form>

Otherwise the input will not be sent.
