I have updated my controller to include an Integer property:

public Integer ChildAccountCount { get; set; }

Then I set the property in my method:

public PageReference updateChildAccountOwnership() { try { Account parent = [Select Id, OwnerId From Account where Id =: parentAcct.ParentId]; List<Account> childAccts = [Select Id, OwnerId From Account where ParentId =: parent.Id]; ChildAccountCount = [Select Count() From Account where ParentId =: parent.Id]; ChildAccountCount += ChildAccountCount + 1; parent.ownerId = acctToByParent.ownerId; DbUtil.save(parent); List<Account> lst = new List<Account>(); for (Account acct: childAccts) { acct.OwnerId = acctToByParent.OwnerId; lst.add(acct); } DbUtil.save(lst); ApexPages.Message msg = new ApexPages.message(ApexPages.Severity.INFO, 'Account ownership updated successfully.'); ApexPages.addMessage(msg); acctToByParent.OwnerId = null; parentAcct.parentId = null; return null; } catch (Exception ex) { ApexPages.Message errMsg = new ApexPages.Message(ApexPages.Severity.ERROR, ex.getMessage()); ApexPages.addMessage(errMsg); return null; } }

In my VF page, I have a command button that calls the above method:

<apex:commandButton action="{!updateChildAccountOwnership}" value="Update" status="ChildAccountsLoadingStatus" rerender="ChildAccountsPageBlock, Msg" onclick="if (!confirmation()) return false;" />

I have a confirm dialog that opens before the update processes, which is where I want to display the property value.

I was trying to get the property value using the following method:

<apex:outputLabel value="{!ChildAccountCount}" id="theCount" /> <script> var total = document.getElementById('{!$Component.theCount}').value;</script>

The problem appears to be that the property value is not set when the confirm dialog is executed.  I want to show how many records are going to be updated before processing the update.

Any ideas?  It seems like I'm close, but can't get the value until after the user confirms and then the update processes and the property is set.
