[jboss-user] [JBoss Seam] - Dynamically rendering more than one select elements in a for

[kindor]

I'm trying to dynamically build a form by looping over a set of fields that have a renderer attribute, which is used to tell what widget should be used to renderer them. 

The problem I'm facing is when the widget is a select element. In this case, the nested f:selectItems load their data from a bean that, if I understand well the documentation, cannot be specified at runtime. Thus, I have hardcoded the bean that provides the data to the select boxes (dataProviderBean.selectItems in my simplified example below). But when the form is rendering, I haven't found any mean by which dataProviderBean can know which select element is being populated. 

What's the best approach for solving this problem ?


  | <h:dataTable var="field" value="#{fieldSet}">
  |         <h:column>
  |                 #{field.name}
  |         </h:column>
  |  
  |         <h:column> 
  |                <h:inputText value="#{field.value}" 
  |                         rendered="#{field.renderer.isInputText}"/>
  | 
  |                <h:selectManyListbox value="#{field.value}" 	
  |                        rendered="#{field.renderer.isManyListBox}">
  |                    <f:selectItems value="#{dataProviderBean.selectItems}"/>
  |                </h:selectManyListbox>
  | 
  |                <h:selectManyCheckbox value="#{field.value}" 	
  |                        rendered="#{field.renderer.isManyselectManyCheckbox}">
  |                    <f:selectItems value="#{dataProviderBean.selectItems}"/>
  |                </h:selectManyCheckbox>
  |         </h:column> 
  | </h:dataTable>
