Recent changes in 'dev' made some of the components stop working. We need to click through firefly viewer to identify the problems and fix it. Below are a few that I've spotted.

Data Sets menu: Form fail validation when they should not. filters and upload file should be nullable.

Catalogs Classic menu: form fail validation without any visual indications. valid parameter is false when passed into validUpdate in CompleteButton.

xyPlot(Scatter Plot) options: Beside X and Y, everything else should be optional(nullable). Even after entering a valid value into all of the fields, 'OK' still fail validation similar to above where 'valid' parameter is false when passed into CompleteButton.

There may be more, please do a quick search to make sure all usage of CompleteButton is good.
