How to add images to list items in a microflow?

-1
I have a dynamic list of products, each product includes some description and an image. Products entity has a generalization from Image entity, so when I manually create a new product item, I can click and add an image. I’m creating a microflow that would automatically create a bunch of products, but it is not allowing me to automatically attach images to them. If the images are in the resources folder, so they are a part of the project, is there any way to add those images to newly created objects in a microflow?

You can use Java actions from Community Commons to accomplish this.  Try GetFileContentsFromFile.  If you pass in the file name and a System.Image object, it should work.

***EDIT***

I got curious, so I tested this.  This was my resources directory:

and I created this microflow

And got the image with no problems.

Yes you can. But you need some Java code. You need to adopt it with the correct module name and directory name.

Create in the resource map of your project a map and put all those images there. Then you can run this code to transform those files into Mendix image documents.
