Javatest 4.2 (applicable since version 4.0):

Configuration Editor input fileds for IntQuestion and FloatQuestion objects require user to enter values according to current locale settings. In contrary PropertiesQuestion with IntConstraints and FloatConstraints require user to enter values in Java-style.

Example:
- customize locale settings for your environment to have ',' (comma) as decimal separator and ' ' (space) as thousands separator.
- start Harness. Open WD for TestSuite that has Interview questions as said above.
- edit values. Note that:
 -- IntQuestion accepts '1 000'
 -- PropertiesQuestion with IntConstraints accepts '1000'
 -- FloatQuestion accepts '1 000,5'
 -- PropertiesQuestion with FloatConstraints accepts '1000.5'

Such inconsistency may surprise and confuse user.
