I am creating visual force pages for to override New, Edit, and Detail view for a custom object. I am using ActionSupport event On Change for a checkbox. Why is it that when I check the checkbox the even that would be considered "on change" the section of the page that should be rendered on this action does not display. It displays if I click outside of the checkbox after the checkbox has been checked.

There is a lot more to add to this extension but I wanted to test that it functioned properly before I coded anymore.

Here is the Controller extension:

public with sharing class GoLiveController { public Go_Live_Process__c glp; public apexpages.standardController controller {get; set;} public GoLiveController(ApexPages.StandardController stdController) { // constructor controller = stdController; this.glp= (Go_Live_Process__c)stdController.getRecord(); Go_Live_Process__c goLives = (Go_Live_Process__c)stdController.getRecord(); goLives = [SELECT Account__c FROM Go_Live_Process__c WHERE id=:system.currentpageReference().getparameters().get('id')]; } //Property for Credentialing checkbox public Boolean showCredentialing{ get{ if(showCredentialing == null){ showCredentialing = false; } return showCredentialing; } set; } //Property for client agreement checkbox public Boolean showClientAgreement{ get{ if(showClientAgreement == null){ showClientAgreement = false; } return showClientAgreement; } set; } }

Here is part of the visual force page:

... <apex:pageBlockSectionitem > <apex:outputLabel value="Client Agreement"/> <apex:inputCheckBox value="{!showClientAgreement}"> <apex:actionSupport event="onchange" rerender="EditForm" status="showClientAgreement" /> </apex:inputCheckBox> </apex:pageBlockSectionitem> <apex:actionStatus startText="(rendering Client Agreement Go Live...)" id="showClientAgreement"/> </apex:pageBlockSection> <apex:actionRegion > <apex:pageBlockSection title="Client Agreement" rendered="{!showClientAgreement}" id="closeoutBlock" columns="2"> <apex:inputField value="{!Go_Live_Process__c.Privileges_issued__c}"/> </apex:pageBlockSection> </apex:actionRegion> ...

Any Ideas? I know how it works and I think it would be okay but I think that users would complain about having to click outside of the checkbox even after they have already checked the box.

Thanks!
