We are upgrading our Tridion GUI, and we have some code that pops up a warning when you try to unpublish components that are in use.
The old code is heavily reliant on
window.dialogArguments.unPublishSelection window.dialogArguments.unPublishPipeline window.dialogArguments.unPublishList
but window.dialogArguments is deprecated and has been removed from most modern browsers. Is there an alternate way of accessing that same information?
