Openrefine: Using a cell value for the Wikidata-Item description gives error "schema is incomplete"

[LibrErli]

For some Wikidata uploads I want to use item-depended created descriptions from a specific column in openrefine. if I drag the column to the Description field it is not possible to save the schema or to change to preview or issues tab.
clicking on save schema occurs the error "Your schema is incomplete so it cannot be saved yet."

(i am working with open refine 3.0 rc1) - maybe i'm running in an error during schema editing?

@LibrErli that's curious… could you give a screenshot of your schema?

Column deDesc contains text values

@wetneb
After same try and error - i can reproduce how the error occues.

First i add a Description term, set the language and type a string in the input field. The schema will be previewed. Afterwards i delete the string in the description field and drag and drop the column deDesc in the inputfield - the error occures.
If i remove the description term, add a new one, select the language and add the column immediately everything works fine!

@LibrEli thanks a lot for the analysis! However I cannot reproduce the problem on my side, neither with Firefox nor with Chromium. May I ask you what configuration you use? (operating system and browser)

@wetneb i am running open refine 3 rc 1 on ubuntu 18.04 firefox 61

I can reproduce this. I think it specifically happens when you delete the text from the Description field, keep the cursor in the field and drag the column into the schema without the cursor leaving the field (I'm guessing this leads the field not being updated and so being treated as empty when you try to save the schema?)

@ostephens great, thanks a lot for the video, I will investigate.
