I would like to know where (specifically in which file and function) the code is executed when a request similar to the one below is sent (via ajax):
This request is sent when a file from e.g. Attach Image -> From the file store is selected and the dropdown field is populated with a list of files. I suspect it has everything to do with CMSMain.php -> getEditForm(), however I'm not sure and don't want to just start hacking away.
Your help would be greatly appreciated!
