[jira] [Updated] (TAP5-2158) Client-side validation of @Size is not working when only min or max is set

["Balázs Palcsó (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TAP5-2158?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Balázs Palcsó updated TAP5-2158:
--------------------------------

    Description: 
Exact version: 5.4-alpha-14

Server side example:

{code}
@Size(min = 3)
private String name;
{code}

On the client side the following function gets executed:
{code}
doRangeValidate = function(element, value, memo) {
      var max, min;

      min = rangeValue(element, "data-range-min", 0);
      max = rangeValue(element, "data-range-max", Number.MAX_VALUE);
      if (_.isString(value)) {
        value = value.length;
      }
      if (!((min <= value && value <= max))) {
        memo.error = (element.attribute("data-range-message")) || "RANGE ERROR";
        return false;
      }
      return true;
    };
{code}

In the above example max is evaluated to NaN and therefore the function returns false causing validation error.

Same applies when you only max is specified in @Size annotation and min is evaluated to NaN.


h3. Workaround 
Specify both min and max.
