I have a visualforce page with custom controller. I have added apex:pagemessages
in a helper static class and for some reason the messages are not displaying on my Visualforce page and I'm not sure if this is a best practice but I have lots of validations to take care instead of doing in the controller I have moved all the code to a helper class.
Helper class for validations:
public with sharing class ValidationHelper
{
public static boolean doValidation(myCustomObject acc)
{
//just few as an sample
boolean b = false;
if(acc.name == '' || acc.name == null)
{
ApexPages.addmessage(new ApexPages.message(ApexPages.severity.FATAL,'Please enter Account name'));
b = true;
}
if(acc.AccountNumber == '' || acc.AccountNumber == null)
{
ApexPages.addmessage(new ApexPages.message(ApexPages.severity.ERROR,'Please enter Account number'));
b = true;
}
return b;
}
}
Controller Class:
Boolean isInValid = ValidationHelper.doValidation(acc);
if(isInValid) { return null; }
even though my isInValid
is true but I'm not seeing any error messages that I'm capturing in doValidation
method
Visualforce page:
<apex:form id="frm">
<apex:pageMessages id="pageMsg"/>
<apex:pageblock title="Detail" mode="mainDetail" >
<apex:commandButton value="Submit" action="{!Submitview}" reRender="frm,pageMsg" />
</apex:pageBlock>
</apex:form>
How can I display the error messages that I'm capturing in Helper class and show it on VFP?
addMessage
is, the message should be added to the current page context. Can you edit your post to include the rerender information, such as the button/actionFunction used to rerender thepageMessages
tag?
