S2 Losing Session in interceptor

[JRD]

Hey there, I have built an interceptor to store and retrieve ActionErrors
using the session for redirect-action results.  The weird thing is I seem to
lose the values the first time it is run through.

private static final String KEY="org.etc...";

public String intercept(ActionInvocation actionInvocation) throws Exception
{
ActionContext actionContext = actionInvocation.getInvocationContext();
Map session = actionContext.getSession();

if (session.containsKey(KEY)) {
Collection actionErrors = (Collection) session.remove(KEY);
if (actionInvocation.getAction() instanceof ValidationAware) {
((ValidationAware)
actionInvocation.getAction()).setActionErrors(actionErrors);
}
}

String result = actionInvocation.invoke();

if (actionInvocation.getResult() instanceof ServletActionRedirectResult
&& actionInvocation.getAction() instanceof ValidationAware) {
if (action.hasActionErrors()) {
session.put(KEY, action.getActionErrors());
}
}

return result;
}

So say I have an invalid session (or timeout).  I catch the exception and
then chain to an action that will build the error message and redirect back
to the login page.  When I step through the interceptor it will be fired
twice.  The first time it is being fired by the action that built the error
message.  Everything looks ok and it adds the action errors to the session. 
The second time is for the action that displays the login page but when that
interceptor is fired, the session that is returned is empty.

This only happens the first time I do this, if I continue to throw
exceptions everything works as I had expected.

All help is appreciated,
Jonathan

Struts 2 & Dynamic Validation results

[JRD]

I am try to migrate an app from struts 1 -> 2

I am trying to do basic validation on a form.  Fields a and b are required.












in the resource bundle I have

errors.required={0} is required.

How do you put dynamic values into these messages so that it shows up:

[blah blah blah] is required.
[Some other field] is required.

Thanks in advance,
Jonathan

Re:

[JRD]

I can't use ${x} because I am not always looking for x.

The basics of what I am doing is building a tile that will print out any
property in my action/form.

So I have some JSP #1 that says







...

And for each definition it inserts JSP #2 that looks like...




I just can't figure out how to write that property tag.  I need it to show
the value of the property passed in.  As I said if I could use runtime
expressions I could just write 

So I can't use the:

Or use  with either the "bare" JSP
2.0+ notation or via .

It would work if I knew to write in 'x' for the currentProperty, but since I
have to evaluate property to get x it doesn't work.

Any other thoughts? Thanks,
Jonathan

Hi there,

I have an action/form that contains properties x, y, & z with values 1, 2, &
3.  I have a .JSP where I want to write out the values of them dynamically.  



How do I write a  using currentProperty that would
result it showing my actions value (1).

If I were using runtime expressions I would write it like

but that is verboten by the tld.

All help is appreciated,
Jonathan
