> I have a PageError component defined as follows:
> .jwc
> <component-specification allow-body="false" allow-informal-parameters="false">
> <parameter name="delegate" default-value="page.validationDelegate" />
> <property name="errorRenderer" />
> </component-specification>
> .html
> <html>
> <body jwcid="$content$">
> <div jwcid="@If" condition="ognl:delegate.hasErrors" class="error">
> <ul>
> <li jwcid="@For" source="ognl:delegate.errorRenderers"
> value="ognl:errorRenderer" style="color:red;" element="li">
> <span jwcid="@Delegator" delegate="ognl:errorRenderer">Error Message</span>
> </li>
> </ul>
> </div>
> </body>
> </html>
> I include this component in all pages which inherit from FormPage which defines the following bean:
> @Bean(ValidationDelegate.class)
> public abstract IValidationDelegate getValidationDelegate();
> My login page (the first viewable page) the component works as expected and I get the following log:
