VF

<apex:dynamicComponent componentValue="{!DynamicPicklist}"/>

Apex

public List<MyWrapperClass> lstPicklistValues{get;set;}
public Component.Apex.repeat getDynamicPicklist() {
        Component.Apex.repeat myDetailList= new Component.Apex.repeat(var='l');
        myDetailList.expressions.value = '{!lstPicklistValues}';

        Component.Apex.OutputLabel theLevelLabel = new Component.Apex.OutputLabel();
        theLevelLabel.value = '{!l.level.Value__c}';

        myDetailList.childComponents.add(theLevelLabel);

        return myDetailList;
    }

The above code displays as below,

{!l.level.Value__c} {!l.level.Value__c} {!l.level.Value__c} {!l.level.Value__c} {!l.level.Value__c}

Its not fetching value instead its hardcoded with '{!l.level.Value__c}'

please help! i am stuck with this since long time

  • hi @KeithC can you solve this issue? – snehakem Jun 2 '15 at 12:40
  • When Apex code such as your getDynamicPicklist method executes there is no {!} substitution mechanism or context available: that is only available in a Visualforce page or component. I suggest looking for a non-dynamic component solution; if you can't find one your can post another question that explains what you are trying to accomplish. – Keith C Jun 2 '15 at 12:51
  • that means dynamic component doesnt work with apex repeat. i feel like there has to be some way. because i didnt find apex:repeat in dynamicComponent not supported list. – snehakem Jun 2 '15 at 12:56
  • Also i tried it by referring this salesforce.com/docs/developer/pages/Content/… – snehakem Jun 2 '15 at 13:08

    I've found dynamic components to be too flawed to use. For example, when there are input fields and a validation error occurs the current values are lost because dynamic components can't be serialized into the view state. – Keith C Jun 2 '15 at 13:28

theLevelLabel.expressions.value = '{!l.level.Value__c}';

  • Bryan, you'd clear up your answer if you also explain it. – Samuel De Rycke Jul 30 '15 at 12:48
