apex:dynamicComponent
This tag acts as a placeholder for your dynamic Apex components. It has one required parameter—componentValue—which accepts the name of an Apex method that returns a dynamic component.
The following Visualforce components do not have dynamic Apex representations:
- <apex:attribute>
- <apex:component>
- <apex:componentBody>
- <apex:composition>
- <apex:define>
- <apex:dynamicComponent>
- <apex:include>
- <apex:insert>
- <apex:param>
- <apex:variable>
Example
<apex:page controller="SimpleDynamicController">
<apex:dynamicComponent componentValue="{!dynamicDetail}" />
</apex:page>
/* Controller */
public class SimpleDynamicController {
public Component.Apex.Detail getDynamicDetail() {
Component.Apex.Detail detail = new Component.Apex.Detail();
detail.expressions.subject = '{!acct.OwnerId}';
detail.relatedList = false;
detail.title = false;
return detail;
}
// Just return the first Account, for example purposes only
public Account acct {
get { return [SELECT Id, Name, OwnerId FROM Account LIMIT 1]; }
}
