We have a list of uploaded documents in Mendix. We want users to select the documents they need, so that in the end all the selected documents will be downloaded to the location given by the user. In the microflow we use the iteration option to download the selected files, but only the last selected file is actually downloadable, because there we get the question if we want to download en where we want de downloaded file to be saved.
The download file is stored in the microflow and at the end, it is send back to the client where it shows the download popup.
An option here would be to have a java action build a zip package out of the files and show that as the download.

The HTTP protocol does not allow to download multiple files at the same time. So this effect can only be achieved if you put them in an archive first.
