                 Key: RF-9913
                 URL: https://jira.jboss.org/browse/RF-9913
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: component-input
    Affects Versions: 4.0.0.Milestone3
            Reporter: Ilya Shaikovsky

Original problem from QE:
"when I set value=20 and step=9 to spinner, 18 is set on the page.
After clicking up arrow, 27 is set (correctly). These differs to 3.3.x
where 20 would be displayed on page and next number would be 27. Is
this difference between 3.3.x and 4.0.x bug or feature?"

both behaviors from 3.x and 4.x are wrong(missed during requirements gathering) and valid is:
 
• base example: http://docs.jquery.com/UI/Spinner#Example
       • Check currency spinner. Manually correct value to 0.50$ and try to click on arrows.

Rules:
any numerical manual input directly in input should be allowed (but considering min and max) and should not be corrected according to step.
any valid numerical value from the model should be set to spinner on rendering and not corrected  according to step.

Step should be considered *only* while using arrows and should be added/substracted to *current value* in input. If in the result will be more or less than max or min limitation - it should be set to boundary value.
The same for correction of wrong direct numerical input. e.g. direct input of 110 when max is 100 should be  corrected to 100.

The same should be considered for slider. Slider also should consider step additionally during calculations when the user slicked on visual bar element.
