Re: 2.1.6 slams a few doors shut, doesn't it?

[Adam Hardy]

Now that 2.1.6 won't let me add to the resultConfig to add my redirect 
httpParameters myself, I figured I'd have to obtain the actual Result object.

The way that DefaultActionInvocation is programmed to do this though makes it 
impossible, despite the Javadocs explicitly stating otherwise e.g. 
http://struts.apache.org/2.1.6/struts2-core/apidocs/com/opensymphony/xwork2/ActionInvocation.html#getResult()

Then I can't call the create result method since it's not on the interface.

Even when I cast the ActionInvocation and call the create method and faithfully 
add my redirect parameter, the result gets overwritten later anyway.

It looks like I must downgrade from here - unless anyone can think of another 
way of programmatically adding the parameters to the redirect URL.

 From the ActionConfig.Builder#build() javadoc:

"The builder for this object.  An instance of this object is the only 
way to construct a new instance.  The purpose is to enforce the 
immutability of the object.  The methods are structured in a way to 
support chaining. After
setting any values you need, call the {...@link #build()} method to create 
the object."


I assume there was some issue behind the scenes with robustness.

For the long term it would be good to have an official struts method to 
set the HTTP params programmatically.

What I'm going to do now is code up a Result class to extend 
ServletActionRedirectResult - someone give me a shout if I'm barking up 
the wrong tree.

Thanks

I'm prevented from adding my redirect parameter programmatically with 
2.1.6!

Look:

Map<String, ResultConfig> resultsMap =
    ServletActionContext.getActionContext(getRequest())
        .getActionInvocation().getProxy().getConfig().getResults();
ResultConfig config = resultsMap.get(resultName);
Map<String, String> params = config.getParams();
params.put(paramName, paramValue.toString());
 
causes:
java.lang.UnsupportedOperationException
    at java.util.Collections$UnmodifiableMap.put(Collections.java:1285)

Or am I jumping to conclusions again?

I think just need to pass a string, instead of an object in the value
param.

Hi,

got a compilation error after upgrading from 2.0.11 to 2.1.6 due to

in com.opensymphony.xwork2.config.entities.ResultConfig

I am doing this:

paramName,
       Object paramValue)
   {
       Map<String, ResultConfig> resultsMap =
           ServletActionContext.getActionContext(getRequest())
               
.getActionInvocation().getProxy().getConfig().getResults();
       ResultConfig config = resultsMap.get(resultName);
       if (config == null)
       {
           return false;
       }
       else
       {
           config.addParam(paramName, paramValue);  // 2.1.6 COMPILE 
ERROR
           return true;
       }
   }


which I can call in my actions in order to put another parameter onto 
the
redirect URL of my result.

In 2.1.6, ResultConfig has no addParam() method anymore.

After checking the upgrade troubleshooting guide and the user lists, 
it seems nobody else is suffering from this problem. Could somebody 
give me an
 idea how to deal with this?
