Ok. I read the OGNL spec and it looks like the way of using maps etc. is
subtley different from Struts1. My JSP now looks like
and the associated Action class has methods
public void setAttribute(String key, Object value)
public Object getAttribute(String key)
The setAttribute method is still not being called (again, I have checked
with debug print statements), but this time in the catalina log I get the
following excepion messages along with a large stack trace
--snip--
Apr 18, 2007 9:57:01 AM
com.opensymphony.xwork2.util.InstantiatingNullHandler nullPropertyValue
SEVERE: Could not create and/or set value back on to object
ognl.NoSuchPropertyException:
com.csc.event.delivery.controller.EventOverviewController.attribute
[java.lang.IllegalAccessException: Class ognl.OgnlRuntime can not access a
member of class com.csc.event.delivery.controller.EventOverviewController
with modifiers "private"]
--snip--
It looks like it wants the actual attribute member to be public, but I
really dont want to do that...
Any help is much appreciated,
James
