There is an action button above each picture. But it is working differently depending on the parity of input$n (in numeric input within sidebar panel). If input$n is odd, clicking on the button changes the label, which is what I want. Else, It does not.
Please find attached the server and ui respectively :
...ANSWER
Answered 2021-Oct-29 at 15:21Looking at the print(excluded$ls[[input$n]]) output, it seems that each time the input$n is triggered, it increments the number of updateActionButton() that will be launched when triggering any input$outN.
So for example, triggering 2 times input$n and then clicking on any input$outN button will launch the updateActionButton twice instead of once. So it first excludes but then reincludes your sample. When input$n has been triggered an odd number of times, it finally ends wit an exclusion of the sample so that's why it seems to work.
Not sure exactly why that happens, but it's definitely because there are two nested observeEvent. Similar behavior may have been observed (pun intended) already.
If you don't nest the two observeEvent, it works as expected:

QUESTION
I have been trying to scrape indeed.com and when doing so I ran into a problem. When scraping for the titles of the positions on some results i get 'new' because there is a span before the position name labeled as 'new'. I have tried researching and trying different things i still havent got no where. So i come for help. The position names live within the span title tags but when i scrape for 'span' in some cases i obviously get the 'new' first because it grabs the first span it sees. I have tried to exclude it several ways but havent had any luck.

Answered 2021-Aug-11 at 22:27You can use a CSS selector .resultContent span[title], which will select all that have a title attribute within the class resultContent.
To use a CSS selector, use the select() method instead of .find():
QUESTION
I have to make an app that scans an NFC card, then takes a picture at the same time and send this information to a server, but my problem is that devices on android 11 doesn't detect my NFC Tag unlike devices on android 6 to android 9. I enable the foreground dispatch when i press a button (to take a picture (in, in2b and out2b) and then disable it only in onPause method. Also, when my app is running, the other apps (like NFC Tools) can't detect any NFC tag unless I stop my app. if anyone has any idea of the source of the problem, its welcome help, thanks Here is my code :
...ANSWER
Answered 2021-Apr-14 at 13:36There have been a number of questions on this recently and it seems to be very device specific and the documentation for the old Camera API says that some devices might block the main event loop of your App and as the old NFC API you are using requires your App to be Paused and Resumed for the main event loop to receive the data from the NFC.
If you are targeting API 19 and above for your App I would always use the newer and better NFC API called enableReaderMode, instead of enableForegroundDispatch.
This newer API gives you more control and it does not require your App to be paused and resumed and the data is handled in it's own thread and won't be blocked by a blockage to the main event loop by the camera.
Note I've not tried using enableReaderMode with camera operations, I just always use it for NFC operations because it is a better method of working with NFC.
