Odd error: apex:pageMessages not displaying any errors in inline visualforce page. Am i missing something?

Question

I am trying to display error messages using apex:pageMessages tag but the error block does not show up in the inline visualforce page. Is there any restrictions that a visualforce page should contains only one apex:pageMessages tag? I have two inline vf page that has been embedded in account detail page. I have tried to throw an exception intentionally to see the errors displaying in apex:pagemessages block in my inline vf page. Also the debug log shows VF_PAGE_MESSAGE, please see below. I have also checked the rendered html for the pagemessage html block but did not find anything. Any thoughts please.

Debug Log:

14:56:00.851 (9851921914)|SYSTEM_METHOD_EXIT|[71]|System.debug(ANY)
14:56:00.852 (9852005206)|SYSTEM_METHOD_ENTRY|[73]|ApexPages.addMessage(ApexPages.Message)

I suspect the issue here is that the apex:pageMessages tag has been evaluated before your getter is called, so even though you are adding the message correctly to the collection, the rendering engine doesn't take it into account as it has already processed the tag.

As the getter can be called multiple times, it doesn't feel like the best place to be adding a message as you could end up with a long list of duplicates. Looking at the code you are also likely to be making a number of web service callouts. A better way to do this would be to carry out the web service callout from the constructor and setup the cci record there, that way you know it will only happen once and the message will be added before the apex:pagemessages tag is evaluated.

Thanks @Bob Buzzard. As per your suggestion, I have changed the code and removed the get method and placed all the webservice code inside of the controller itself. But again the issue persisted. And after that i just take the apex:pagemessages and placed it above apex:pageBlock and it renders properly. Thanks for your guidance.

You essentially have to do 1 of 2 things in order to get the errors to show up.

1) Get the messages to be thrown somewhere from constructor execution.

2) Rerender the messages after an error has been thrown.

Note: I also noticed that your getCustCreditInfo is likely firing several times. I believe each get call makes it fire again.

Thanks @dphil. I have updated my question with the debug log lines. Please have a look. Also i have checked debug log thoroughly that the getcustcreditinfo method called only one time. There is no issue with apex:pagemessages in my another inline vf page which is also embedded in the same account detail page.

The Note I made doesn't really effect your problem. I was just noting it for a potential side effect. On your other VF page, is your message being rerendered somehow? That would explain why it would work and this one doesn't.

Jun 16, 2014 at 19:14
Yes, @dphil. I checked the vf page where apex:pagemessages has been working. But this one is really taking my time. But i think it should be a very silly mistake from my side unfortunately i cannot find it out.

The other guy pointed out something that might be helpful. Try using an apex:outputPanel instead of that div tag.

Jun 16, 2014 at 20:05
Thanks @dphil. I have changed the code and made apex:pagemessages inside of apex:outputpanel, but still it is not working no error is displaying on the top of the inline vf page. Any thoughts?

I too display warnings and confirmations via ApexPages.addmessage()

ApexPages.addmessage(new ApexPages.message(ApexPages.severity.CONFIRM,msg));

I remember having some problems with that before I put my pagemessages tag inside an outputpanel tag (see below)

<apex:page standardController="LogEntry__c"  extensions="LogEntryController">
 <apex:sectionHeader title="Manage " /> 
    <apex:form >    
            <apex:outputPanel id="pnlMessages" >
                <apex:pagemessages ></apex:pagemessages>
            </apex:outputPanel>
        ...
