I want to implement a dynamic, dynamic custom component in visualforce and apex. Therefore I created a new component:

<apex:component controller="SidebarController">
    <apex:repeat value="{!components}" var="component">
        <apex:dynamicComponent componentValue="{!component}" />

And a corresponding controller:

public without sharing class SidebarController
    public List<Component.c> components {get; set;}

    public SidebarController()
        components = new List<Component.c>();

        components.add(new Component.c.TestComponent());
        components.add(new Component.c.TestComponent2());

Do you know from which type the component value has to be?

I already tried the following types:

  1. Object -> Cast fail
  2. UIComponent -> Not available in apex
  3. Component.c -> core.apexpages.quickfix.QuickFixException
  4. Component.apex -> core.apexpages.quickfix.QuickFixException
  5. Component -> general issue

Do you know the correct type of a component in apex?

  • If your dynamic components will allow input, be aware of Field Values In Dynamic Component Not Retaining After Error - the normal error handling lifecyle is broken.

  • Hmm ... The doc uses Component.Apex.xxx if the component being returned is apex.xxx; in your case, you are looking for the super class above Component.Apex.xxx - and it is not Component.Apex as that causes a compile error. The SFDC example similar to what you are doing enumerates each component by type explicitly and adds to the childComponents property: salesforce.com/us/developer/docs/pages/… . The childComponents property acts as a reference to a List of Component.Apex objects.

I think this is the correct type:

public List <ApexPages.Component> childComponents {get; set;}

Here are the docs.

  • No problem. That happens to me all the time. :) Aug 19 '14 at 1:46
