You need to pass an argument to setValue(), setValue() and setValue(undefined) doesn't work for SimpleTextArea or TextBox either, for that matter.

Replying to bill:
I think setValue() should get anything, usually taken from a data store, (null and undefined too) and the (form) widget should display it in a proper way.
TextBox define setValue(), with no type associated to value argument, and setDisplayedValue(), where value argument must be a string. filter() and format() methods let you customize it.
TextBox setValue() don't work, butsetValue(null) clear the field. Other TextBox methods format() and filter() respond to null and undefined in explicit way (see source).
Source structure and reference to #5329 let me think that desired behavior is that described at beginning of this comment.

My patch is very simple to change code as less as possible but give SimpleTextArea a similar behavior.
format() and filter() support in SimpleTextArea would be even better.

The documentation for TextBox.setValue() is confusing/vague because it describes not just TextBox but all widgets that extend TextBox. However, the only thing officially supported by TextBox is setValue("a string") or setValue("").

For SimpleTextArea to be completely consistent with TextBox's actual behavior, we would need setValue(null) to clear the field and setValue(undefined) to do nothing.

I could change it to ignore setValue(undefined) but would you prefer that to the current behavior?

More similar to TextBox's actual behavior I think is the better.

Inheriting SimpleTextarea from TextBox and not from _FormValueWidget would give a full behavior matching and format/filter support, but probably should be an other ticket ;-)

Yah, perhaps SimpleTextArea? should extend TextBox?... Doug?

onChange does not work with the current SimpleTextarea?. I recommend this ticket get moved back to 1.2.
