EL Expression for a document's Parent

I'm trying to write an EL expression so I can place it in the Advanced Configurations section where, given a File document type, if the parent of the File is a Folder document type, then I want the "State" and "Workflow" widgets to be hidden. Here's what I've found so far:

documentManager.getDocument(document.getData().getParentRef()).getParent("Folder") == 'hidden'

Any ideas for getting this EL expression right? I'm planning on putting this in the Advanced Configuration section in the widget.

Thanks!

Hi,

The variable "document" exposed by the layout service has been deprecated, you should use "layoutValue" instead.

This variable will map the object that the layout binds to.

In a basic form, the layout will be bound to a document model, so you should be able to use the following syntax:

documentManager.getDocument(layoutValue.getParentRef()).getParent("Folder") == null ? 'hidden': mode

If your widget is actually inside a listing, the layout is bound to a PageSelection element, so you can get the wrapped document by calling #getData() on it. In this case, the following expression should work:

documentManager.getDocument(layoutValue.getData().getParentRef()).getParent("Folder") == null ? 'hidden': mode

I haven't tested these, please tell if there are issues with them.

Also see the documentation about layout expressions and variables.
