-----------------------------------
Attachment: StrutsVariableResolver_diff.txt
> Updated the StrutsVariableResolver to add OGNL support for resolving variable
> names
> -----------------------------------------------------------------------------------

> Key: WW-1415
> URL: http://issues.apache.org/struts/browse/WW-1415
> Project: Struts 2
> Issue Type: New Feature
> Components: Expression Language, Misc
> Affects Versions: 2.0.0, 2.0.1
> Environment: All
> Reporter: Christopher Waring
> Assigned To: Don Brown
> Attachments: StrutsVariableResolver_diff.txt

>
> Changed StrutsVariableResolver to first return the current Action if the
> Action name matches the requested variable name. Otherwise try the value
> stack to resolve the variable. Otherwise delegate to the original jsf
> variable resolver.
> This allows you to use things like the following with your JSF EL expressions:
> <h:outputText value="#{billingAction.billingActions[editId].baId}" />
> (Where "billingAction" is the name of your action, "billingActions" is a List
> property of the action, "editId" is a Long property of the action, "baId" is
> a property of a model object with in the List.)
> This will also work:
> <h:outputText value="#{billingActions[editId].baId}" />
> (Same as above but starting with a property of the action rather than the
> action itself.)
