this is a text area field. I did try

value:""

but that did not clear the field either. I also have a list / record field I want to clear as well and from what I can gather I need to use

value:[ ]

for that.

""

works correctly for me on a Text Area in a Client Script using the

currentRecord

reference

I think SS2 is supposed to honor

null

to clear a field, but it doesn't seem consistent
