Accessing Java class / object attributes in CheerpJ based PWA
Thanks so much for the help. I just checked out the library mode and it’s exactly what I need. I’ll try to request imjoy team to upgrade. Based on your experience would upgrading imjoy to CJ3 be challenging?

Steps to reproduce issue:
1. Head over to https://ij.imjoy.io/?run=https://gist.githubusercontent.com/sspathak/902c5d7d1e8de08c7232f790cb5511b6/raw/3f498140a3cd83ce3e88b34c00582ca77e3b0b72/gistfile1.txt
2. Inspect element and go to console.
3. Run
let get_image = await cjResolveCall("ij.WindowManager", "getCurrentImage");
4. Run let im = await get_image()
5. Run Object.getOwnPropertyNames(im)
You'll see that the property names have an integer suffix.
This integer suffix seems to follow the order in which the instance variables are defined at https://imagej.net/ij/source/ij/ImagePlus.java9 replies
