Subject [jira] Updated: (STR-2880) Validating array integers
Date Mon, 29 May 2006 07:16:16 GMT
     [ http://issues.apache.org/struts/browse/STR-2880?page=all ]

thomas bailey updated STR-2880:
-------------------------------

    Description: 
There seems to be some issue with validating arrays on integers:

html:

<html:select property="types"  multiple="true" size="3" >
<html:option value="1">should work</html:option>    
<html:option value="2">should work as well</html:option> 
<html:option value="blah">this will fail validation</html:option>       
</html:select>

actionform:

public class PropertyFilter implements Serializable 
  {
  private String[] types;
 
    public String[] getTypes() {
    return types;
  }
    public void setTypes(String[] types) {
    this.types = types;
  }
  }

validation.xml:
   
<formset>
<form name="PropertyFilterForm">
  
<field property="types" depends="integer">
<arg0 key="text.validation.type"/>
</field>
   
</form>
</formset>

Even if all values are  integer, it will fail validation regardless. According to http://www.strutskickstart.com/IndexedPropertiesandValidation.ppt#18
I should 
do something like:
   
<field property="types" indexedListProperty="types" depends="integer">
<arg0 key="text.validation.type"/>
</field>
   
This time, it does indeed check all the values are of type integer, however, 
if you do not select anything (the field is not required) the result is:
   
java.lang.NullPointerException
org.apache.commons.validator.Field.getIndexedProperty(Field.java:796)
org.apache.commons.validator.Field.validate(Field.java:891)
  ..

Also having scoured all documentation in current and future builds and there is no example
of validating an integer array.
