Not sure if this is a Redactor or a CB issue, or what role Collections plays in this.
When I make a new child page in Collections, add an image w/title CB field, upload an image BEFORE the new resource has been saved at least once, the directory placeholder of
+parent_alias is ignored.
If I save the resource first and then upload an image it goes into the placeholder directory as expected.
Using MODX 2.8.1-pl, MODX Cloud hosting, CB 1.10.0-pl, Redactor 3.1.0-pl. (I see there is a CB update so will install and test again.)
Note- will test with a non-Collections child page and report back. EDIT: Confirmed this happens also with child pages that are not part of a Collection. Page needs to be saved at least once or the
+parent_alias placeholder is ignored.
