Struts 1 , Use an array to capture multiple parameters

[Sagar Rohankar]

Hi Ranchers,
I am crating JSP page for 'Multiple Supplier RegistrationForm' , Where more than one, the same field repeats , like address, emails of supplier, etc. I created a bean with String Array property., Now when user submit buttons then It gets collected into a bean array property. Now how can i perform Validation on This indexed Array for each separate Supplier Information .

Thanks in advance !!

You can specify an indexedListProperty attribute for a field that will cause it to validate the property as a part of a list. Example:

<field property="email" indexedListProperty="bean" depends="required">
     <arg key="Email" resource="false"/>
</field>

The above will work with a field that looks like this in your JSP:

<html:text name="bean" property="email" indexed="true" />

or like this:

<html:text property='<%="bean["+index+"].email" %>' />
