transfuse | small script to backup , compress , and restore your plasma | Continuous Backup library

I think you're right on what is causing the issue, and I'm pretty sure this is an environment problem. By that, I mean that I see Figure is assigned via read.csv() in your script, but it's "outside" the server part of your app. This effectively means it will be hidden from the server when running.

Try moving these lines to be within server:

It would make more sense to set the volume parameter to 0 for those that are not transfused. Here is an example:

If your getExample method is supposed to always return a list, then yes, change its return type to List. But since you're passing List.class as an argument, it looks like you want to have a method that can return both lists and non-lists depending on which class object you pass it.

If so, that's not going to work the way you might be hoping. Your method in this case returns just List, the raw type. To make it return List, you'd have to pass it something like a hypothetical List.class, but there's no such thing. Generic type parameters are erased at compile time, so List and List are really both the same class; they don't have separate class objects, so a class object argument can't tell your method what kind of list it should return.

You'll probably need to try a different design approach. Since this is clearly a simplified example, you might be able to get more help if you post more details about what you're actually trying to accomplish.

You have to edit the .form-control class so that it doesn't have a fixed height. Here's a demo, where I added height:auto to the .form-control class.
