[Bug] Issue With Dynamic Page

Developer Programs Writing SmartApps
1

I am not certain where to post bug reports or issues, but just noticed an issue when using dynamicPage in a smart app. Using the code below, the function is being called twice every interval causing the logging to spiral out of control.

preferences {
    page(name: "testFunc", title: "Test Func", content: "testFunc")
}

def testFunc() {
    log.debug 'testFunc()'
    dynamicPage(name: "testFunc", title: "Test Func", nextPage: "", refreshInterval: 5, install: true, uninstall: true) {
        section("Example...") {
        }
    }
}

The logs for this SmartApp look like this:

As you can see the number of concurrent function calls is increasing exponentially every cycle. It would be a great help if anyone could confirm this behavior on their end. Thanks!

Try setting refreshInterval to 0…

4

Try thinking next page and actual name, or, just remove that.

5

Setting the refreshInterval property to zero disables the refresh entirely, which is not my intention. I do need the refresh enabled so that I can periodically execute a function.

6

Removing the nextPage="" property did not change the behavior =/ good call tho as it is unnecessary.

Yea, I get that, it was just a test…

def testFunc() {
    log.debug 'testFunc()'
    if(!state.pageRefresh ) { state.pageRefresh = 2 }
    state.pageRefresh =  state.pageRefresh + 2
    dynamicPage(name: "testFunc", title: "Test Func", refreshInterval:  state.pageRefresh , install: true, uninstall: true) {
        section("Example...") {
        }
    }
}
updated() {
     state.pageRefresh = 2
}

Use this code to ease off the refresh. nevertheless, it’s still a bug on ST’s end

Nice work-around! Works pretty well from my initial tests.
