1) Making this change would require changing code that is locked by a template or a translator. The change will be discarded.
HOWEVER, opening the same document in DW8.0.2 does not produce the error.
I have cleared the cache and the error still occurs. Additionally, I removed the behavior from the page, and it managed to remove some template information, rendering the page completely unusable. It would be faster to re-create the page than to try to fix this seriously deficient extension.
I am very disappointed.
EDIT: I'm sorry, I'm talking about Universal Form Validator, which exhibits the same deficiencies as Calendar 2.
