Can anyone send me sample code for extending DynaValidatorForm and
implementing reset() method that will clear the text fields on reset.

Thank you,

Is this something where just adding "initial" will work for you?

<form-property name="username" type="java.lang.String"
initial="&lt;username&gt;"/>

This will affect the behavior of an html-reset control, because it
determines the initial value of new form elements.

Otherwise, if you're going to actually override
DynaValidatorForm.reset, something like this might work for you
(method signature truncated) :

reset(mapping, request) {
   set("username", "<username>");
}

This is one step removed from the html-reset control, because it will
be executed within your servlet context, *not* from within a browser.

What's the actual problem you're trying to solve.

Thanks David,
But I need sample code. Can u provide it? I got your logic but finding it
difficult to implement. The main problem is how to get the property name at
runtime. I have many forms that extend the DynaValidatorForm.
Thank you,
AM

Hmm, guess you were asking about extending DynaValidatorForm.  I must
have been thinking of some other question that was similar to this
one.  Anyway, a DynaValidatorForm is a DynaBean, so you can call
set("propertyName", "reset Value") from your reset override method.
These API versions aren't exact, but I don't think these classes have
changed much:

http://struts.apache.org/1.3.8/apidocs/org/apache/struts/validator/DynaValid
atorForm.html
http://jakarta.apache.org/commons/beanutils/commons-beanutils-1.6.1/docs/api
/org/apache/commons/beanutils/DynaBean.html

My code is as following...
struts-config.xml

<form-beans>
        <form-bean name="DynaLoginForm"
type="org.apache.struts.validator.DynaValidatorForm">
            <form-property name="username" type="java.lang.String"/>
            <form-property name="password" type="java.lang.String"/>
        </form-bean>

HTML has the concept of a reset button:

   http://www.w3.org/TR/html401/interact/forms.html#reset-button

As stated in the link above, when a user activates a reset control,
the form values are set to their *inital values*.  This may not be the
reset behavior that you're looking for.

One way to implement a reset button that "clears" form element values
is with JavaScript.  You might do something like:

<button onclick="resetForm(); return false;">Reset</button>

<script type="text/javascript">
    function resetForm() {
        // acquire form reference, e.g.
        var myForm = document.forms['myForm'];

        // loop through elements
        for(var i = 0; i < myForm.elements.length; i++) {
               // check element type and implement reset
               //  your code goes here
        }
    }
</script>
