Bug 5.8 ? update properties with NULL become 'null' on string (vocabulary)
I get in 5.6 : A vocabulary field (save as a String)
I do an update on this parameter with a value that is not initialized, so it should be set to NULL also in 5.8
Nevertheless, when I use this value in a freemarker template, with 5.8 the value changed from NULL to the string 'null' so every tests I did failed, because it's not anymore set to null.
If I'm not wrong, it looks for me as a problem in the update properties chain ?
