Simple Form

[xlugo]

Hi, I use Richfaces 3.1.3 anf Myfaces 1.1.4

I Have this code:

<h:form>

   <a4j:region id="region1">     
        <h:selectOneMenu value="#{myBean.selectedCountry}" id="countries" >
            <f:selectItems value="#{myBean.listCountries}" />
            <a4j:support actionListener="#{myBean.countryChanged}" event="onchange" reRender="states" />
            <h:outputLabel value="Countries:" for="countries"/>       
        </h:selectOneMenu>
   </a4j:region>   
      
   <a4j:region id="region2">
        <h:selectManyListbox id="states" value="#{myBean.selectedListStates}">
            <f:selectItems value="#{myBean.listStates}"/>
            <h:outputLabel value="States:" for="states"/>
        </h:selectManyListbox>            
   </a4j:region> 

this code is ok.

---------------------------------------------------------------------------------------------------------------------------------------

Then, I need to use the selected values (like parameters) in a method to show a table, but i dont know how to do it.

I need a action button.

    <a4j:region id="region3">   

       <a4j:commandButton actionListener="#{myBean.showTableCountryStates}" reRender="table" value="show country" >
       </a4j:commandButton>                  
    </a4j:region>

......................

myBean:

public void showTableCountryStates(ActionEvent event){

         //read   selectedCountry
         String paramCountry = this.selectedCountry;

         This code no working

        //logic to the table

you should remvoe region around the button - it's limits processing to just button.

And b.t.w if you even stucked with 3.1.x because of environment requirements - it's highly recommended to use 3.1.6 which is the latest and more stable version.

Let me try it, thank you very much-

I have this code:

<h:form>

   <a4j:region id="region1">     
        <h:selectOneMenu value="#{myBean.selectedCountry}" id="countries" >
            <f:selectItems value="#{myBean.listCountries}" />
            <a4j:support actionListener="#{myBean.countryChanged}" event="onchange" reRender="states" />
            <h:outputLabel value="Countries:" for="countries"/>       
        </h:selectOneMenu>
   </a4j:region>   
      
   <a4j:region id="region2">
        <h:selectManyListbox id="states" value="#{myBean.selectedListStates}">
            <f:selectItems value="#{myBean.listStates}"/>
            <h:outputLabel value="States:" for="states"/>
        </h:selectManyListbox>            
   </a4j:region>

<a4j:commandButton actionListener="#{myBean.showValues}" reRender="country" value="execute" >
    </a4j:commandButton>

<a4j:region id="region3">                      
        <h:outputText value="#{myBean.selectedCountry2}" id="country"/>
</a4j:region>

I want to read the selectedCountry value (and selectedListStates)

my bean:

   // private selectedCountry, selectedCountry2

   //get and set methods ...

    public void showValues(ActionEvent event){

        this.selectedCountry2 = this.selectedCountry;       
       
    }

If I just select  a item from selectOneMenu I get the correct value; but when I select a item from selectManyListBox I get a blank value.
