Just out of curiosity, why are you starting with Struts 1 at this point?

Attachment: user_187288.ezm (zipped)

Because it's probably still the most widely used Web Framework still. So I
figured I'd hit this one first.
I've got books on Struts 2, JSF and Wicket on my bookshelf to read next!

Hi again Antonio,
1) Tiles PMC member? What does PMC stand for? A contributor to Tiles or is
PMC some kind of Tiles spin off?
2) I discovered this problem and took a look at the code, and fixed on my
side.
Hopefully you won't have to do it many times, but sometimes it helps.
Uh?
Should my code have worked then?
Is there a bug in Tiles/Struts integration then?  If you've fixed this how
can I get latest build?

PMC=Project Management Committee. I am both a committer and I have the
power to decide the future of Tiles (yeah I've got the power! :-D )

Possibly it's a bug, though I did not try to find out.

>  If you've fixed this how can I get latest build?

I don't think it's fixed. However you can check the latest version
checking out the Subversion repository:
http://svn.apache.org/repos/asf/struts/struts1/trunk/
Anyway check it in JIRA  if the bug has been already filed:
https://issues.apache.org/struts/
If not, file a new bug report and, if you can, post a patch.

Ciao
Antonio

This is really bizarre.
I'd tried changing the html link to "forward" after initial "action" version
didn't work. Then changed it back, created a war and deployed in Tomcat
again. Suddenly everything works. 
I'm wondering if Tomcat had some sort of ghost image of prior deployment
that had exactly same war named miniHr.war. 
My guess is the "work" folder that didn't get purged on redeployment perhaps
and as a consequence first time I deployed the tiles version, the non-tiles
version was still lingering around from the prior deployment..
Darn it!

I'm not sure what you're asking.

To extend the S2 tags themselves you might need to do any or all of the following, depending on your needs:

* add tag attributes to the component and tag classes
* add additional Java code
* regenerate TLD
* modify FreeMarker templates

Some might be easier to extend than others.

That's expected behaviour; it's what the HTML 'reset' input type does. 
Reset will reset the form inputs to the values they had when the page 
was loaded. If you want a different behaviour, you will need to 
implement it yourself (either client-side with JavaScript, server-side 
(using a submit button instead of a reset), or some combination of both.

Yes you did - and that's why I know a lot of Java and only a little Groovy.
(and cannot see if anybody has answered your question)

Anyway, this should be the same in Java and Groovy: String.split uses a 
REGULAR EXPRESSION to split.
A period (.) is a wildcard for "any character" and therefore regards 
every character as a separator with "nothing in between" :-)

You must escape the period, it should work with split("\\.")

Good luck!

Great!  I'm glad it worked fine.  I'll merge your documentation additions as
soon as I have a moment, thanks for providing them.

I like your idea of generating multiple flash map IDs, it seems like a good
solution would make the implementation more flexible.  Feel free to modify
the code and upload it here - again if I have some time I'll try to have a
look at it also.

As for setting a timeout value on the flash map, the idea's interesting but
I think it would only delay the problem.  Sure putting a 60-second delay on
the map would allow it to survive to quick refreshes, but it wouldn't solve
the case when a user returns to this page later using the back button; plus
it would be possible to clog the session with long-lived flash maps if not
used correctly.  On the other hand, maybe it would solve enough cases to
motivate adding this functionality; plus giving a choice to the developer
can be a good thing.  Maybe the Struts2 seniors would like to give their
opinion on this?

To implement this I'd have the result add a timestamp to the map and the
interceptor check for the timestamp's validity instead of starting a timer
though, it would be much lighter.

Cheers,
GB

 Hi Conference

but
I need load freemarker template dynamically. For example:
In page is selectBox (<select>) with items:
- template1
- tempalte 2
- template 3
When user click in item template1, I want to return him view, which use
template1.
When user click in item tempate2, I want to return him view, which use
tempate2.
etc.
 
I need help how to do. I need not exactly code way, only help how can i do

You can use OGNL in the result like this:

 <action name="test" class="com.acme.TestAction">
  <result name="success" type="freemarker">${template}</result>
</action>

then you can have a getTemplate() method in your action that returns
the right template.

Hi,

I have one question regarding iterator. I have one simple list that contain three values:
List
{ id, value, date } and I'm iterating through this list. And I want to
show in my list a sum for value for every day at the last row that
contain that date, like this:

id__value___date_______sum
----------------------------------------------------------
1__10_____20.5.2008
2__15_____20.5.2008
3__15_____20.5.2008___40
4__12_____21.5.2008
5__15_____21.5.2008___27
6__12_____22.5.2008
...

I'm now have done all iterating except this sum column. Do you have any ideas how efficent can I do this ?

In the documentation[1] for the Stream result type we have a:

<param name="contentDisposition">filename="contacts.xls"</param>

This was causing the problem. A simple change to:

<param name="contentDisposition">attachment;filename="contacts.xls"</param>

solved the issue.

Hope this may help someone out there

Hi,

when you have the translations in a resource bundle, as you have now
with your package.properties, you cannot simply get the translations
from the stack, but have to invoke the getText method from you
TextProvider.

The TextProvider interface usually is implemented by your action as
soon as you extend ActionSupport. If it doesn't yet, you'll have to
change this, or place a text provider on the stack yourself.

Then just use an expression like %{getText(displayName)}.

Bye,
-Ralf
