Okay..so i'm using AjaxForm and I'd like to have a form errors (if there
are any) shown above the form when the request comes back.
I'm used to tracking errors as specified in Kent Tong's tapestry 4 book.
trying out Tong's error tracking with AjaxForm, I get this error:
Error converting value for template parameter delegate: No type
converter for type org.apache.tapestry.valid.IValidationDelegate is
available.
What's the *right* way to handle server-side validation?
I'm set up with the following:
/////////////////////////////////HTML:
<span style="color:red">
<ul>
<span jwcid="errors">
<li jwcid="@If" element="literal:li"
condition="ognl:currentFieldTracking.inError"><span jwcid="error" /></li>
</span>
</ul>
</span>
<form
jwcid="[EMAIL PROTECTED]:AjaxForm"
listener="listener:onEmail"
updateComponents="ognl:{'errors'}"
delegate="beans.delegate"
>
....my form stuff here...
<input type="submit" jwcid="[EMAIL PROTECTED]:AjaxSubmit" />
</form>
//////////////////////////////////SPEC:
<page-specification>
<property name="currentFieldTracking" />
<component id="errors" type="For">
<binding name="source" value="beans.delegate.fieldTracking" />
<binding name="value" value="currentFieldTracking" />
</component>
<component id="error" type="Delegator">
<binding name="delegate"
value="currentFieldTracking.errorRenderer" />
</component>
</page-specification>
//////////////////////////////////JAVA:
...
@Bean
public abstract ValidationDelegate getDelegate();
....
public void onEmail(){
....
}
