The time zone is not working correctly for me.
Hello,I’m having an issue when working with the time zone. The problem is the following: I’m from Spain, where my time zone is GMT +01:00. The problem arises because I have a Date Picker in which I select the day to insert it into a PostgreSQL database. So, if from Mendix I insert the date of January 1st, 2025, it inserts December 31st at 23:00 in the database, subtracting 1 hour. The same thing happens in summer: if I insert July 1st, 2024, it inserts June 30th at 22:00 due to daylight saving time, showing two hours less. My database is also set to Madrid/Europe time zone. How can I solve this? Best regards and thanks.

Couldn't deploy sandbox. Something went wrong error while deploying MDA.
Hi, I've been trying to publish my app to the Mendix free tier cloud as usual, but I keep getting the error "Something went wrong error while deploying MDA." I've been facing this issue since last Friday, and I can't seem to find what the problem is. I even tried creating a new app project, importing the same code, and publishing again, but I'm still stuck with the same error. I've also reached out to Mendix support but haven't heard back from them yet. My Mendix version is V9.24.14. Has anyone else run into this issue before? I'd appreciate any help or advice. Thanks a bunch!

Issue with Excel Importer - Decimal Separator Not Working as Expected
Good day everyone, I am using the Excel Importer module in my Mendix application, and I am facing a problem when importing data from Excel. My entity has an attribute called Product/Number (String). I want to ensure that the values in the Excel file use a period (.) as the decimal separator instead of a comma (,). However, when I import the data, for example, if the Number attribute in the Excel file is 4,2, Mendix seems to convert it to 4.3 instead of throwing an error as expected. I would appreciate any guidance about it. Thanks all.

Mendix API and Security
Hello, I'd like to know what's your favorite to prevent object creation using the mendix api, for users that are locked out of creating those objects using a nanoflow or a microflow logic. Even if I have just read rights for the entity members, with the logic below, I can create a infinite number of empty objects in the database. mx.data.create({
entity: "MyFirstModule.Cat",
callback: function(obj) {
console.log("Object created on server");
mx.data.commit({
mxobj: obj,
callback: function() {
console.log("Object committed");
},
error: function(e) {
console.error("Could not commit object:", e);
}
});
},
error: function(e) {
console.error("Could not commit object:", e);
}
});

Localize time format in Calendar widget
Hi all, I use Mendix’ Calendar widget for displaying availability statuses of employees. When I create a Beschikbaarheid object on one particular day, the time is formatted as desired (i.e., 04:00 – 10:00). However, when I create a similar object over multiple days, the time slot is being formatted according to US standards (i.e., 4:00 AM – 5:00 AM). The Calendar widget is based on the (JS) Full Calendar. The documentation mentions, and the code clearly shows, the usage of Locale to localize certain aspects like time formatting. As far as I know, a user’s locale is determined through the browser, server or geolocation. Yet, I then still don’t understand why I keep getting two different time formats in the same context. Any suggestions?

manage role concept
Hi there, I would like to create different roles in my app. Each role grants read access to all objects. The role determines which groups, including associated categories, the person has write access to. I am currently encountering the problem that the buttons for editing objects are displayed even if the person does not have write access, but only read access. This means that the visibility 'Show the action button for applicable roles' is not sufficient. Here's an example: I have "GroupA" and "GroupB". Max is allowed to write on GroupA, but should not be allowed to edit GroupB. Anna, on the other hand, is allowed to edit GroupB, but not GroupA. The same behavior for the categories. You can see in the Screenshot below that Max can see all buttons, even if he has no write access to the belonging objects. Max view: desired view: What I could do: I can limit the buttons for the group using visibility. However, this no longer works for the categories (error "Retrieving over association is not allowed here"). My only alternative seems to be placing the button in a DataView with a microflow checking write permissions, then limiting visibility based on the result. Because I have this issue in many places and with many different entities, I prefer not to implement this solution using microflows+dataviews. Do you have any suggestions for a more efficient solution? Thanks in advance! Best regards, Simone

Flexible Permissions: Managing User Profiles in Real Time
Is it possible to create profiles such as administrator and user directly in the running system? I am developing a system and would like to know if it is feasible to create user roles directly through the system while it is running. The idea would be to allow a manager to create new user profiles, such as attendant, salesperson, among others.

Native Deeplink from an Email
Hi All, I'm trying to implement native deeplinking into our mobile app. The specific use case is as follows: 1. From the web, Admins can create provisioned accounts for Mobile users. 2. These Mobile users will receive an email with a link to the mobile app. 3. This link will redirect the user from the email to a specific page in the mobile app where they'll set an initial password. 4. After setting an initial password, they'll be redirected to the Login page. We currently have provisioning, MFA, and password set/reset working for web but haven't figured out deeplinking from an email to the mobile app. Any help or insight is appreciated!
