When I add a statement of type String (or URL) and enter "foo " as value, accidentally with a tailing whitespace (often occures with copy-and-paste) and click save, I get the Error-message Could not save due to an error. Malformed input: foo but the tailing whitespace is not visible, so nothing points me to why the input is malformed.
Possible solutions:
- Remove tailing whitespaces automatically
- Put the input in Quotationmarks so that the space is getting visible
- Make spaces visible by formatting characters
- Detect tailing whitespaces and give an appropriate error-message
