[jira] [Updated] (PLUTO-650) Objects such as portletConfig are available during JSP EL resolution even when portlet:defineObjects is not present

     [ https://issues.apache.org/jira/browse/PLUTO-650?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Neil Griffin updated PLUTO-650:
-------------------------------
    Description: 
The {{<portlet:defineObjects/>}} is a feature that enables the JSP pageContext to have attributes like {{portletConfig}}. One benefit of this feature is that JSP EL expressions can resolve these objects. For example:
{code:html}
<span>portletConfig=${portletConfig}</span>
{code}
If {{<portlet:defineObjects/>}} is missing from a JSP, then the objects should not appear as JSP pageContext attributes, and EL resolution should return {{null}}.

The JSR 378 TCK contains a test that expects the lack of {{<portlet:defineObjects/>}} to mean that the JSP pageContext attributes will not contain values like {{portletConfig}}.

h3. Steps to Reproduce:

- Create a portlet that contains the following JSP content:
{code:html}
<span>portletConfig=${portletConfig}</span>
{code}
- Deploy the portlet
- Add the portlet to a Pluto portal page
- View the Pluto portal page

(/) Expected Result: 
{noformat}
portletConfig=
{noformat}
(x) Actual Result:
{noformat}
portletConfig=DriverPortletConfigImpl@8407
{noformat}

The reason why the value is found, even without the presence of {{<portlet:defineObjects/>}} is because the WeldELResolver is present in the JSP ELResolver chain and knows how to resolve the value.
