I have a custom page. When I on click save button it does not save anything. Is there anything wrong with my code that I could not find? Thanks
public PageReference save() { if(controller.save() != null) { PageReference congratsPage = Page.pitu3; congratsPage.setRedirect(true); congratsPage.getParameters().put('id',controller.getId()); return congratsPage; }return null; } There must be some validation or system error as suggested by Keith. I would suggest to use below to show error to user or at at least use system.debug to see what is going on.
Try{ if(controller.save() != null) { PageReference congratsPage = Page.pitu3; congratsPage.setRedirect(true); congratsPage.getParameters().put('id',controller.getId()); return congratsPage; }return null; Catch(Exception e){ ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR, e.getMessage()); ApexPages.addMessages(myMsg); return null; } 
controlleris the StandardController, one reason might be that there is a data validation error on the save. Make sure you have anapex:messagesin your Visualforce to see the error output. This is only relevant to thecontroller.save()returning null path.
