This is a follow-up to a question that was answered earlier. Here is the link to that question: Mendix Forum - Question Details. I got the Excel Importer to raise an error whenever I try to import a file. The app also will freeze at this point, and it does not know how to handle the issue. Attached is a screenshot of the error I am getting. It is different from the original issue and felt that it warranted a different post. What I can say is that I have gotten the excel importer to work on other apps using the same setup I am using here. Any help would be appreciated! Edit: I noticed that the excel importer did not find any rows to import. When I tried it on a different app, it was able to find the records correctly. Here is a screenshot of the App not finding the rows.
