https://answers.axonivy.com/questions/1674/auto-initialisation-number-0-from-jsf-view<p>Hello, we have a datatable in jsf view, one column is a number in bean. After submiting form (ivy event) we receive initialised number 0, so our validation cannot check if user inserted it manually (field is mandatory, 0 must be explicit inserted). How can we avoid the auto initialisation ?</p> <p>Karel</p>enMon, 18 Apr 2016 15:34:00 -0400https://answers.axonivy.com/questions/1674/auto-initialisation-number-0-from-jsf-view/1735<p>Hi, we have found the solution to set up </p> <p>ivy.vm.additional.options=-Dorg.apache.el.parser.COERCE_TO_ZERO=false</p> <p>But it must be done in all environments (each server, each designer in Development Team). Is there any possibility to set this in Run time (API ?)</p> <p>Karel</p>tauserMon, 18 Apr 2016 15:34:00 -0400https://answers.axonivy.com/questions/1674/auto-initialisation-number-0-from-jsf-view/1735https://answers.axonivy.com/questions/1674/auto-initialisation-number-0-from-jsf-view/1680<p>I think you can determine if the 0 was auto initialized by using the IvyDefaultValues helper:</p> <pre><code>ch.ivyteam.ivy.scripting.objects.util.IvyDefaultValues.isDefaultObject(Object) </code></pre> <p>There exists also a community project 'dataclass-nuller' which helps to nullify auto initialized data class values.
