Hi
I am using commons validator 1.3.1 and am using indexedProperty's for
String[] arrays.
I build up the list on the jsp dynamically so there could be one or more
entries with the same name.
Here is my struts config entry as part of a DynaValidatorForm
<form-property name="abc" type="java.lang.String[]"/>
Then in my custom-forms.xml I have the following configuration rules
<field property="abc" indexedListProperty="abc"
depends="required,integer,intRange">
<arg key="aRI" resource="false" position="0"/>
<arg name="intRange" key="${var:min}" resource="false"
position="1"/>
<arg name="intRange" key="${var:max}" resource="false"
position="2"/>
<var>
<var-name>min</var-name>
<var-value>0</var-value>
</var>
<var>
<var-name>max</var-name>
<var-value>250</var-value>
</var>
</field>
This configuration works fine if there are 2 or more fields in the form
with the name 'abc', however when there is only one commons validator
sees it as a string and the following method throws a Validator
Exception
/**
* Returns the size of an indexed property from the object we're
validating.
*
* @param bean The bean to extract the indexed values from.
* @throws ValidatorException If there's an error looking up the
property
* or, the property found is not indexed.
*/
private int getIndexedPropertySize(Object bean) throws
ValidatorException {
Object indexedProperty = null;
try {
indexedProperty =
PropertyUtils.getProperty(bean,
this.getIndexedListProperty());
} catch(IllegalAccessException e) {
throw new ValidatorException(e.getMessage());
} catch(InvocationTargetException e) {
throw new ValidatorException(e.getMessage());
} catch(NoSuchMethodException e) {
throw new ValidatorException(e.getMessage());
}
if (indexedProperty == null) {
return 0;
} else if (indexedProperty instanceof Collection) {
return ((Collection)indexedProperty).size();
} else if (indexedProperty.getClass().isArray()) {
return ((Object[])indexedProperty).length;
} else {
throw new ValidatorException(this.getKey() + " is not
indexed");
}
}
The method signature explains this as it says this will be thrown if it
is not an indexed property.
Is what I am trying to achieve possible with the current version of
commons validator? If so is there some configuration changes needed?
Thank you in advance
David
