This is a lazy answer, but I don't think the default ValidationDelegate
provided by tapestry actually renders the error message - it just marks
things as being in error. (perhaps the default should be the other way
around ? )
You can see an example of how to extend the validationdelegate to do what
you want at the bottom of this page:
http://tapestry.apache.org/tapestry4.1/usersguide/validation.html
Something along the lines of your @Delegate component (which I'm assuming is
supposed to print out all the error messages? ) is also found here:
http://svn.apache.org/viewvc/tapestry/tapestry4/trunk/tapestry-examples/Workbench/src/java/org/apache/tapestry/workbench/components/form/ShowError.java?view=markup
Note that this particular example only prints out the first error, not all
of them.

Hi list,
I've constructed a small test case using Tapestry 4.1.1. I'm trying to
validate a text input field
using the 'required' validator. The FieldLabel for this TextField is
indicating an error, but the
Delegator doesn't display it.
This is my template:
<font color="red"><b><span jwcid="@Delegator"
delegate="ognl:beans.delegate.firstError"></span></b></font><br/><br/>
<form jwcid="@Form" delegator="ognl:beans.delegate"
success="listener:doTest">
<label jwcid="@FieldLabel"
field="component:testField">Test</label>
<input jwcid="[EMAIL PROTECTED]" value="ognl:test" displayName="Test"
validators="validators:required" />
<br/><br/>
<input jwcid="@Submit" />
</form>
The page-specification for this page contains nothing except for the
corresponding class reference.
The page class looks like this:
public abstract class Test extends BasePage {
@Override public String getClientId() { return null; }
@Override public void setClientId(String arg0) { }
@Bean public abstract ValidationDelegate getDelegate();
@InjectPage("Home") public abstract IPage getHomePage();
public abstract String getTest();
public IPage doTest() {
if(getDelegate().getHasErrors())
return null;
System.out.println(getTest());
return getHomePage();
}
}
After fighting with this for 4 hours I've got the strong feeling that I'm
missing something here. So
all you experts out there please help me :)
Cheers
Uli
