Combobox setting value

[msantana]

Hello,my name is Matias and i´m new to Seam Framework.
I am making a lot of tests, before i decide to make my project with it.

I have a simple-for-you-problem, but i spend a lot of hours trying to figured it out, without success.
I make a project using seam gen of a simple, product with categoria entity.
The scenario is simple like this. I have a product which has a category. Simply.
The sem-gen made a view where i can put the name of the client. But insted of make a comobox with all roles i can select it makes a grid where i have to enter to the page of roles and select one.

So i decided to put a combo there, And here's where i get stucked.
I made this:

 <s:decorate id="categoriaField" template="layout/edit.xhtml">
                <ui:define name="label">Categoria</ui:define>
                <rich:comboBox value="#{productoHome.instance.categoria.categoriaId}"
                                     suggestionValues="#{categoriaServiceBean.findAll()}" 
                                     defaultLabel="Seleccione..." 
                                     required="true"
                                     directInputSuggestions="true" />   
                                    <s:selectItems var="categoria" itemLabel="#{categoria.descripcion}" itemValue="#{categoria.categoriaId}" />
                    <a:support event="onblur" reRender="categoriaField" bypassUpdates="true" ajaxSingle="true"/>
            </s:decorate>

But the problem is that when i select the category i want, the event is not setting the value to productoHome.instance.categoria. Then  my save button is not settibn enabled.

<h:commandButton id="save"
                          value="Save"
                         action="#{productoHome.persist}"
                       disabled="#{!productoHome.wired}"
                       rendered="#{!productoHome.managed}"/>

Where am i wrong? what am i doing wrong?

Thanx all!!

Someone who has a clue?

There are several problems in your code.

The first is that the value property for rich:combobox points to the categoria.categoriaId. This won't work. Look at the <s:convertEntity>. Your code should look like:

<rich:comboBox value="#{productoHome.instance.categoria}"
          defaultLabel="Seleccione..." 
          required="true"
          directInputSuggestions="true" />   
    <s:selectItems 
         var="categoria"
         value="#{categoriaServiceBean.findAll()}" 
         label="#{categoria.descripcion}" 
         itemValue="#{categoria}" />
    <s:convertEntity/>
</rich:comboBox>
 

In order to enable the save button you also have to modify the isWired() method so that it doesn't check if categoria is null. The pattern for wired/not wired entity home needs a page refresh to work.

YES!! It work but the combobox is showing me the items with numbers! but the numbers aren´t the id´s however i want to show the descripition of the object, or the toString().

Matias,

  <rich:combo> works as a suggestion box and supports only a list of characters. your are using the below :

<s:selectItems var="categoria" itemLabel="#{categoria.descripcion}" itemValue="#{categoria.categoriaId}" />

instead use :

<s:selectItems var="categoria" itemLabel="#{categoria.categoriaId}" itemValue="#{categoria.descripcion}" />

the itemValue appears in the combo list and not the itemLabel. <rich:combo> is different from <h:selectOneMenu>.
