Trigger does not display error msg on screen
I have a before insert trigger on an object called Request that has to throw an error when a condition gets satisified. The trigger works, but it does not display the error on the vf page itself. It goes into the application to display the same. Please help out.
Apex Trigger
trigger ReqValidation on pba__Request__c (before insert)
{
list<pba__Request__c> relist = [select id,pba__Contact__c,status__c, createddate from pba__Request__c];
for(pba__Request__c r :trigger.new){
for(pba__Request__c req:relist){
if(r.pba__Contact__c == req.pba__Contact__c){
if((req.status__c == 'Active' || req.status__c == 'Pending')&& (req.createddate.date().daysbetween(System.today()))<7)
{
r.adderror('Close the Active or Pending request');
}
}
}
}
}
