Ron9 addError() to a dynamic referenced field
Im stuff trying to use the field.addError() method to post validation errors on my VF page.
The standard absolute method call works fine e.g.. customObj.fieldName.addError('myString');
BUT I need to use this with fields I dynamic reference on a generic SObject.
I've tried genericObj.get('fieldname').addError('myString'); but this validates to a method does not exists error
Can anyone help me, please?
Best Regards

To use the addError, you will need to apply it on the field. Although I am not absolutely sure of how, I would start by using field tokens.
Thank you Jerun Jose.
That is of cause true.
Does anyone know how to get a field token for a field from a SObject? Preferable by using the fields API name

Hi Jerun Jose
Thanks again.
The code below shows how I tried to use the gotten SObjectField token, but this still don't give kind of field reference I need. The addError returns an no such method error. But I guess this also makes sense as the reference needs to be to a specific object instance to be able to show the error message at the right field on the page.
Map<String, Schema.SobjectField> fields =obj.getSObjectType().getDescribe().fields.getMap(); fields.get(fieldNameString).addError('error text');Any other suggestions?
Best Ronni
Can you try something in line with Dynamic visualforce?
Basically, you can do AccountObj['AccountNumber'] in VF to get the account number for the account record denoted by AccountObj . Wondering if that can be extended for this purpose.
I don't think it is possible to add the error from the VF XML. Actually I also think that obj[fieldname] is just the same as the obj.get(fieldname) in APEX. It really puzzles me if this isn't possible with dynamic field references.
