However starting Android 11 there are restriction to writing file in external or internal storages, and there is also another restriction that is not allowed to attach file automatically from app file directory.

            Update events in calendar after change in variable - Fullcalendar
            Asked 2021-Mar-25 at 08:11

            Using Fullcalendar with Vue.js, I'm passing the initial events from a variable, but I need that after this variable is updated, the events were updated in the calendar also. The documentation seems to be clear about that:

            But I've tried this and nothing happens, the events keeps as the first renderization.
            Also I've looked in many SO related answers about this topic but most of them are applied with JQuery which is not my case.
            I can't figure out how to aply this in a correct way.
            Thanks in advance for your attention...

            ANSWER

            Answered 2021-Mar-25 at 07:27

            Your events don't update because you're using a static event source - that array was copied to fullCalendar when it was initialised. Updates to it have no effect on the calendar because fullCalendar is using a different, older copy of the array.

            And fullCalendar has no way to refetch anything because you didn't give it a source to fetch from. If you want re-fetching to work then you need to provide a dynamic event source. There are two techniques you can use to do that, both described in detail in the documentation:

            1. Events as a JSON feed - where you simply specify a URL which will return JSON event data directly. fullCalendar will call this URL whenever the date changes - or whenever you call refetchEvents - and pass the current start and end dates of the calendar as query parameters, so the server can return a list of events correctly filtered by date.

            2. Events as a function - where you provide a callback function which fullCalendar will call whenever the date changes - or whenever you call refetchEvents - and passes the current start and end date as parameters to the function. The function can then do whatever you want in order to fetch events - e.g. make a custom AJAX call, or call another function or whatever. When the events are ready you pass them back to fullCalendar using the "successCallback" function supplied as a parameter to the main callback. There's an example in the documentation.

            ssl certificate issue for jgit in javafx app image versus javafx app runtime
            Asked 2020-Nov-12 at 15:37

            I have developed a simple JavaFX app using jgit, that is allowing users to play with git.

            When the app was started from the IntelliJ idea, I was able to clone the GitHub repo using my jgit implementation of the "git clone" command without any issues. But as soon as I created an image from my app and started the app from the image, I am getting an SSL certificate issue:

            Exception:org.eclipse.jgit.api.errors.TransportException: Secure connection to https://my-github-repo.git could not be established because of SSL problems.

            I am trying to understand why I am getting the SSL certificate issue only when I am running the app from the image. Can somebody explain that? I understand that I can disable SSL verification (there are some questions answered on that topic), but I want to know why it is working from IDE and not from the created image...

            here is my simplified git clone implementation for http:

            Answered 2020-Nov-12 at 15:37

            The most likely situation is that you are missing a module in the JRE image related to crypto that is required to authenticate the SSL connection.

            What jdk.crypto.* modules are in the final image? Perhaps if one of these is missing it will affect the ability to handle the SSL certificates?

            • jdk.crypto.cryptoki
            • jdk.crypto.ec
            • jdk.crypto.mscapi

            Since some aspects of the security/crypto code are done via service providers, perhaps when you generate the JRE image you should pass the "--bind-services" option to "Link in service provider modules and their dependences"

            You will need to share more details about how the image is created and what specific errors are reported. Try to include the full stack trace of any reported exceptions.

            What version of Java 11 are you using? Could you be running into this: JDK 11 SSL Error on valid certificate (working in previous versions)

            (It is unlikely if you are running with the same JDK version in the IDE and the packaged image, but thought I would mention it just in case it gives you a hint.)
