org.apache.tapestry.BindingException: Unable to read OGNL expression
org.apache.tapestry.BindingException: Unable to read OGNL expression
--------------------------------------------------------------------
Key: TAPESTRY-1482
URL: https://issues.apache.org/jira/browse/TAPESTRY-1482
Project: Tapestry
Issue Type: Bug
Components: Framework
Affects Versions: 4.1.2
Environment: Tapestry 4.1.2 (5/19), ognl (5/19)
Reporter: Heath Nielson
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:
DEBUG org.apache.tapestry.BaseComponent - Begin render Login/$PageError

However, when I go to the next page which embeds the PageError component, I get the following error:
DEBUG org.apache.tapestry.BaseComponent - Begin render AddClient/$PageError

The error disappears when I set org.apache.tapestry.disable-caching to true.

org.apache.tapestry.BindingException: Unable to read OGNL expression
Posted by "Heath Nielson (JIRA)" <de...@tapestry.apache.org>.
[ https://issues.apache.org/jira/browse/TAPESTRY-1482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12497321 ]
Heath Nielson commented on TAPESTRY-1482:
-----------------------------------------
I forgot to add that both the login page and the AddClient page which share the same superclass where validationDelegate is defined reference the component without passing in a parameter. They rely instead upon the default value (i.e. <span jwcid="@PageError" />). It appears to me that this issue relates directly to the default-value. The ognl reference to page.validationDelegate appears to bind that page's class with the first reference and a ClassCastException is thrown when a different page tries to use the same default-binding. When I explicitly set the parameter in the page class, this error no longer occurs.
I'm not sure if this is working as designed or not but this error did not occur in 4.1.1.
