Hello Everyone, I am trying to import excel file into Mendix application. I am following the instructions provided on the page: https://docs.mendix.com/howto/integration/importing-excel-documents However I am stuck at the below step as I am not able to understand what to do after I download Download the Excel Importer and Mx Model Reflection modules from the appstore. Create menu items for the ExcelImportOverview and the MxObjects_Overview pages. Those pages already exist within the _USE_ME folders of the downloaded modules. I copied these patchs into at C:\Program Files\Mendix\7.18.1.40272\modeler but when I execute these nothing happens. I am not sure If I am doing anything wrong. Please suggest, thanks in advance. Regards, Puneet

Zip/Download files
Hi, I tried to add a button that download multiple files (1 excel report and some photos) in the same time. In order to do that, I tried to zip these files, with differents solutions that I found, but for the moment nothing works. I first tried to download the module "Create Zip" on the app Store, and call the Java action "ZipDocuments" in my microflow. It takes 2 parameters, a file document previously created that will contain the files zipped and a List of file documents that contains my 3 files. I created these 2 objects, I added the files to the list and I put the right parameters in the Java action. But when I test it, nothing is downloaded. I tried to see with breakpoints if the file document that should contain the zip was empty, but no, after the java action call it has contents and a size that seems to be well. Afterwards, I tried a second way, that I found over here : https://forum.mendixcloud.com/link/questions/6444, (code here : https://pastebin.com/PkJJCxZE). This link gave a code that was similar but not exactly the same, this time there is a return object that is the zip file. I created the java action with the right parameters, I called the it, then when I try to download the returned file, nothing is downloaded again. And I have no errors. Did someone manage to make it work ? I put a picture of my microflow in order that it is clearer. Thank you in advance.

Need help locating Prefill Page contents based on the entity" as indicated in Rapid Developer Module 4.5.2
Hi, I am currently following the Rapid Developer Learning Track and I am on Module 4. I am trying to create a "detail" for when the Add button is activated by the user. In 4.5.2 he instructions state to select the option "Prefill page contests based on the Course entity". I can't locate this option. Therefore, when I created the form, generic attributes were generated on the detail form. I don't know how tie these attributes to the course data source. Question 1: Is there a Prefill page option that I missed? How can I tie the generic attribute to the correct data source?

Pass list as argument to the rest URL from mendix application
I am new to mendix. I have a mendix application that syncronizes its few tables from another database. One of the tables has some employees information (say salary info). The employee table is not synced. Now the requirement is not to list the inactive employees from a page showing the employee salary. I want to remove the salaries from this page where the employee is inactive. I am trying to add a workflow to pass the list of this salary details table to a java application where I will filter out the inactive employees and give back the list as response. But It seems while calling the rest url, I can not pass the list. Please tell me what is the correct way to do this. Thanks,

Setting .focus on first input field
I sometimes run into situations where Mendix will not set autofocus to the first input field automatically. This happens mainly in full-page forms (pop-ups are usually fine) and may be due to styling. Regardless; I figured I should be able to resolve it quite easily with a bit of javascript, so I threw a couple of code snippets at it through the browser console by way of test, but to no avail.
$(".FirstFocus").focus(); or
$(".FirstFocus:first").focus(); where FirstFocus is the class of the input field, both yield an output in the console:
[div#mxui_widget_TextInput_16.mx-name-textBox1.FirstFocus, prevObject: jQuery.fn.init(1), context: document, selector: ".FirstFocus:first"] and TextInput_16 is indeed the ID of the field I'm trying to set focus on. However, no focus is set. My guess is I'm overlooking something dead obvious, but I rarely mess around much with the Mx frontend in this way. Anyone with a push in the right direction?

Getting out of memory error after upgrading to mendix version 7.18
Hi There I upgraded to mendix 7.18 on Monday and i am now getting out of memory errors on my long running microflows that run in the background of my application. I have tried on different machines and reloaded the postgresql data base and increased the maximum of lock per record size to no prevail. I made the mistake of pushing this to production as we didn't pick up the errors as we normally run these microflows a number of times a day to minimise the record list size. I had to go back in history and rerun the information for a complete day and this is when the errors happened. Nothing has changed in the portion of the system except the mendix upgrade. I can opsimize the microflows so they commit less or break the jobs up, but that will take time as all the functionality will have to be tested end to end again. And im not sure that will solve the problem. Are you guys aware of this problem or is there a setting i need to change?

QR Scanner without native app deployment
Hi all! Is it possible to use a QR/Barcode scanner widget without having to publish the app to mobile app stores (i.e. have it natively installed)? I want to scan QR-codes with my app and store the information to which the QR code refers in my database. However, I have no experience with creating native apps, so I want to try it in a webapp first. Kind regards and thanks in advance! Steve Jonk

Project members in a company
We have a lot of projects, and new members (employees or stagairs) that come and go. Everytime I make a new project I need to choose every person individually to give access to the project. When a person leaves I need to remove this user in every project. This results in a lot of clicking, I tried to automate it with the Mendix api but it seems there are no services for this. I do see something about security groups that I don't see on on sprint/cloud/developer portal. Do we really need to add and remove a users on project level? Or can this be accomplished on a company level?

Document Template - PDF keeps creating empty page at end
Hi, I've been working on a pretty simple document template, the basic structure is > Header > Data View >> Template Grid >>> Formatted tables Whenever i generate and download as a PDF, i see all the expected rows, but it will consistently append an extra page (With the header still) as a last page of the document, with no rows returned. Even if the rows from the template grid stop cleanly halfway through the previous page. Does anyone know what might be causing this additional blank page to be included, and how to stop it? Cheers
