When i do a renderEmailTemplate and the template contains:Dear {!NullValue(Contact.FirstName, "Sir or Madam")} please callI get an error saying Field NullValue(Contact.FirstName, "Sir or Madam") does not exist. Check spelling.If the template just has {!Contact.FirstName} it works if I select a contact that doesn't have a NULL firstname. The NullValue is supposed to fix the situation where there is no data in a certain field.Here's the code:body = 'Dear {!NullValue(Contact.FirstName, "Sir or Madam")} please call'; String[] RenderArr = new String[]{body}; MergeRes = Messaging.renderEmailTemplate(currentContact.Id,currentContact.Id,RenderArr); for ( Messaging.RenderEmailTemplateBodyResult mRes : MergeRes){ if( mRes.getSuccess() == true) { // Do This when it works } else { List<Messaging.RenderEmailTemplateError> Errs = mRes.getErrors(); for ( Messaging.RenderEmailTemplateError mErr : Errs ) {// Display errors here ShowErrors('Render Err at ' + mErr.getOffset() + ' ' + mErr.getMessage() ); } } } }Does anyone know how to fix this as the NullValue bit i used is exactly what it says to do when you create a tet template.Thanks
