More than 1 Sendablechooser

Sendable choosers are great, but I would caution teams against using them. At GTRC we were rarely able to establish coms through the smart dashboard, and many other teams were having this problem as well. Smart dashboard is not a very reliable option, so I would warn against using it to select your auto. We ended up changing our selected auto through a code re-upload before every match, although we'll be using a set of physical switches on the robot in the future.

What programming language do you use?

We had big issues with SmartDashboard last year when we were using LabVIEW.

We switched to Java this year and have had no issues with SmartDashboard or SendableChoosers (we use 6) through 2 competitions.

We've used Java and Sendable Choosers for 2 years now. Last year it was horrible. There were multiple matches at all of our competitions where we ended up without field-centric driving on our swerve drive because we used a SendableChooser to indicate which direction the robot was facing at the start of the match.

This year it has worked without any problems for us, and we have 3 SendableChoosers.

We're programming in Java. While you might not have problems in a particular year, I'd really advise against it. You never know when it's going to act up, and this can change from event to event. One of our mentors was the volunteer that diagnosed some of the larger SD problems in 2014, and he feels it's poorly written and prone to problems.
