Dynamic UI Elements with Dynamic Input Variables - How to Access Variable

🚧 Developers Coding Questions

No, that's the code that worked correctly. What wasn't working was setting the inputs dynamically instead of putting them all out explicitly.

So, I was trying to do this:

def pageMainPage() {
    dynamicPage(name: "pageMainPage") {  
        section() {
            input name: "checkNumber", type:"NUMBER", title: "Number of checks to perform each day",description: "Must be a whole number between 1 and 6", range: "1..6", required: true, submitOnChange: true, width:4
        }
        section(){
           (1..checkNumber).each{
            def num = it
            input(name: "time${num}", type: "time", title: "Daily check #${num}", submitOnChange: false)
           }
     }

That is what won't work. Sorry I wasn't clearer. But yes, I know that worked.

That won't help. When I put that in right before that, it comes back with 4 but I still can't save the page. Even when I moved the dynamic crap to ANOTHER page, it still didn't work and poped the Null error. So, I don't think it's possible to define inputs that way. You were defining pages not inputs. Maybe that's the difference.

Ah, I was wondering why you were doing it that way...haha.

FWIW, this does work for me though--sounds like this wasn't?

definition(
    name: "Test App",
    namespace: "Blah",
    author: "Blah",
    description: "Test app",
    category: "Convenience",
    iconUrl: "",
    iconX2Url: "",
    iconX3Url: ""
)

preferences {
    page(name: "pageMainPage", content: "pageMainPage")
}

def pageMainPage() {
    dynamicPage(name: "pageMainPage") {  
        section() {
            input name: "checkNumber", type:"NUMBER", title: "Number of checks to perform each day",description: "Must be a whole number between 1 and 6", range: "1..6", required: true, submitOnChange: true, width:4
        }
        log.debug "checkNumber = $checkNumber"
        if (checkNumber >= 1) {
            section(){
                (1..checkNumber).each {                
                    input name: "time{$it}", type: "time", title: "Daily check ${it}", submitOnChange: false
                }
            }
        }
    }
}

SON OF A #$$#&%#* !!!!! OMG!!!! ALL I WAS MISSING WAS A CHECK THAT IT WAS >=1?!?!? AAHHH!!!!

I am so absolutely pissed right now. I literally spent the entire day trying to get this working, and that is all I was missing !?!?! I didn't even have to move it to the other page. I just had to add:
if (checkNumber >= 1)
Thank you for helping me figure this out but at this point I wish it had been something bigger because that's just stupid. Why does it matter if I write in the check for the value if the value is correct? It isn't null so, why should i have to check that it isn't? You don't even need the value check. This works too:
if (checkNumber)
OMG.....SERIOUSLY?!?! Somebody has got to be screwing with me. lol

:rage: :boom: :face_with_symbols_over_mouth:

if (checkNumber) also works due to Groovy truth: if an integer, any value other than zero or null is true. I was just a little more explicit. It would still fail if null when creating the Range because Groovy doesn't like that. There may be a more creative way to avoid it, but something like that is what I normally do. Glad you got something working!

This is probably one of those things that makes total sense if you're a coder but it still ticks me off that it was something so simple. I've been working on this off-and-on for weeks. I finally just decided that yesterday was the day I wanted to get it working. Glad you were there to help. :slight_smile:
