Comparator in .c3ui file


is it possible within the “comparator” attribute in the .c3ui declare more then one comparator - for instance I need to check if the values is != null and >= xxxx .



If you’re asking about comparators for fields in FilterForms, no, there can only be one comparator for a given field.

For individual fields elsewhere that you are writing your own logic for, you can make use of classes that extend C3.validation.Validation to apply custom validation on your values.
