Text Field Validation Gives An Error Even When Its Not Blank

I have been developing a javascript based widget and came the need to add validation to the widget,apparently with the listbox and client validation enabled,an error pops that the field is required yet it has text in it. (The text box containing accepting and commisioning tabs)

See the attached Image:

Im presuming this is a bug in Yii,but I thought It would be good to have a discussion about it first, before flaging it.
