Without wrapping the tag in an <aur:if..> block, is there a better way to do the following conditional attribute:  A little more detail behind it: If it's a mobile device, I need it to run the blur event, but not if it's running on a desktop.  Conversely, if it's a not on mobile I need it to run as a change event.  (This is to handle some quirkiness in the iPhone multi-select dialog.)  I've tried variations on the code snippet above to have the third operator just be thigns like true, false, blank, no third operator, but the browser always throws an error.  I've also tried different ways of using IF, but I either my syntax isn't working or you can't do that.  Instead I created a lightning component function that does nothing so I can successfully include the third argument.  Seems like there should be a better way, though.
 

The following example in Trail "Developer Beginner/Apex Basics & Database: Write SOSL Queries" is incorrect:  The last part should say "...containing the Man word." rather than "...containing the SFDC word."

I am working on Mulesoft Integration module Automate Order-to-Cash Process Using MuleSoft Flow Designer, while on step Trigger SMS Using the Twilio Connector, STEP 7 indicates  copying following code:
Body: "Order for " ++ vars.OppDetails.Name ++ " has been placed.
Details:
" ++ "OrderID: " ++ payload.OrderID as String ++ ", Tracking: "
++ payload.TrackingNo ++ ", ETA:" ++ payload.ETA as Date
The above code in the transform indicates error in Anypoint Platform:
