Hello there! I know from Tapestry in Action that we can access the
first error from a ValidationDelegate class. Is it possible to access
all of em'? like:
<span jwicd="@Foreach" source="ognl:delegate.errors" value="ognl:error"> ...
</span>

Hi,
I attached a class called "MyDelegate" which extends from
ValidationDelegate (If the attachment doesn't come through let me
know). This is the class I use for my validation delegate. There is a
method inside the class called getErrors() which returns all the errors.
This is a snippet from my border component that displays all the errors:
<span jwcid="@Conditional"
condition="ognl:page.delegate.hasErrors">
<div class="AlertBad">
<b>Please correct the following errors before
continuing:</b>
<ul>
<span jwcid="@Foreach"
source="ognl:page.delegate.errors" value="ognl:page.delegate.currentError">
<li><span jwcid="@Delegator"
delegate="ognl:page.delegate.currentError.errorRenderer"/></li>
</span>
</ul>
</div>
</span>
cheers, scott.
