user_185053.ezm (zipped)I dont think so. Can you please tell why we need that? you can use lookup dispatch action if you want to chose action depending upon criterion.
Thank you.

There is good practice to start Tiles definitions with dot -> .tiles-defs
I don't see ant forwards in your struts-config.xml, could you past them here?

Good catch Lukasz! Now I remember that:
*Struts-Tiles does not support forward actions, only forwards inside normal
actions*

user_185056.ezm (zipped)i point the issue by myself.
the main issue is i have not given the
<controller processorClass="org.apache.struts.action.TilesRequestProcessor"
bufferSize="4096" debug="0"/>
in struts-config.xml.
after i give its working... thanks for giving me the best pratices on
tiles...
if u still find any issues in my code pls say so that i can have a
correction....

Attachment:
user_185057.ezm (zipped)dont you think it would be better practice naming tiles like this:
tile.def (*.def are like .jsp but virtual pages)
and only class tiles should be named with dot first like this .class-name?

Well, there is no guideline/best practice defined for Tiles definition
names, so you can do your own :-D

user_185051.ezm (zipped)I use Maven, and if you look at struts 2.0.11.1's dependencies
(http://www.mvnrepository.com/artifact/org.apache.struts/struts2-core/2.0.11.1)
you'll see that it's Freemarker version 2.3.8 it depends on. I can't
override this in Maven, even if I attempt to exclude it and force the latest
version of Freemarker:
....
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.0.11</version>
<exclusions>
<exclusion>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.12</version>
</dependency>
....

user_185052.ezm (zipped)Actually thats an interesting post. To my mind it doesn't demonstrate a
solution. It demonstrates the problem.
Here is why I think this.
Struts 2 is just frankly brilliant for people doing test first development.
The classes you create really are POJOs. There are no dependencies on any
framework in my action classes. For example parameters are parsed well away
from my action and the values are set using simple properties, things like
sessions are simply maps. It is a truly new world for those of who have
suffered the horror of mocking http requests, responses, context and the
like.
But this simple scenario brings all that pain flooding back. I add a line in
my action like this...
String yadaYada = getText("some.doodad");
And my lovely world comes unraveled real quick. Now I need mock objects up
the ying-yang.
I started using the tutorial from the link posted (I am an Arsenal fan btw,
so got two for the price of one, thanks), but it still doesn't provide a
simple solution to the problem. To get this to work I have to build not just
the application context but a mass of supporting objects to get a web
application framework up and running before I can test my simple POJO.
I am not going to give up just yet, but I think I am still going to have to
look for another way.

user_185055.ezm (zipped)Actually thats an interesting post. To my mind it doesn't demonstrate a
solution. It demonstrates the problem.
Here is why I think this.
Struts 2 is just frankly brilliant for people doing test first development.
The classes you create really are POJOs. There are no dependencies on any
framework in my action classes. For example parameters are parsed well away
from my action and the values are set using simple properties, things like
sessions are simply maps. It is a truly new world for those of who have
suffered the horror of mocking http requests, responses, context and the
like.
But this simple scenario brings all that pain flooding back. I add a line in
my action like this...
String yadaYada = getText("some.doodad");
And my lovely world comes unraveled real quick. Now I need mock objects up
the ying-yang.
I started using the tutorial from the link posted (I am an Arsenal fan btw,
so got two for the price of one, thanks), but it still doesn't provide a
simple solution to the problem. To get this to work I have to build not just
the application context but a mass of supporting objects to get a (partial)
web application framework up and running before I can test my simple POJO.
I am not going to give up just yet, but I think I am still going to have to
look for another way.
Cheers,
Paul B.

user_185059.ezm (zipped)While outward facing web application get the most publicity, I know
that most of us are heads-down on internally-facing applications
designed for fellow employees to use over the corporate intranet.
I'm trying to put together a list of the typical types of applications
that enterprise developer write in real life. For example, my last
project involved a system to track drafting, granting, monitoring, and
enforcing water permits administered by a government agency. We would
create an initial record for a permit, and then add child records to
track progress through the workflow, and also update the master record
along the way. For management, a key item here is a tracking report,
which we exported to Word (using a third-party tool) for better
formatting. For engineers, a key item was a flexible search system to
quickly find a master or child record. Other interesting features are
workflows where one task leads to another. When we completed one task
(child record), the next is often implied, and so we had a workflow
that would default the next task to work on when a current task was
closed. Another interesting requirement was that sometimes master
items were merged under another uber-master-item, becoming, in effect,
child items themselves. In most cases, the application simply exposed
business models that we designed into the database, so the application
has little business logic of its own. Most of the workflows were
designed to find, list, edit, or view one database entity or the
other.
So, if anyone else is up for sharing, I'd be interested in hearing
what sort of things other people are doing these days. (If your not
comfortable posting the list, feel free to mail me direct.)

user_185060.ezm (zipped)I completely jumped the gun. My test was flawed and on fixing it, I found that
struts was reloading its config on my dispatcher.init() call, and then again
just before the request but without my config and so ignoring the configured
Dispatch that I set!
I tried the other approach but I can't see any way to get hold of the Dispatcher
(since Dispatcher.getInstance() returns null before I launch the request).

It has definitely solved a big problem. Now, i can show the correct data of
two tabs, submit them and have correct results. Actually, my case is very
simple, as i told you that the two tabs will not be related, so, each tab
will be submitted independently without needing each others data because
there is no common data. So, everything is fine. EXCEPT.....
If i submit one tab the page submits and as a result of this the other tabs'
data is lost. By lost i mean that the changes i made in other tabs are reset
because the page is submitted. I am still unable to find out how to make
each tab ajax based. Here is my jsp code.
<s:url var="test1" value="demo/DefaultAllowanceDetailsAction.action"/>
<s:url var="test2" value="demo/LibraryFormDefaultAction.action"/>
<sx:tabbedpanel id="tabbedPanel" useSelectedTabCookie="true">
<sx:div id="div1" label="Allowance Details" href="%{test1}"
refreshOnShow="false" preload="true">
<s:action name="demo/DefaultAllowanceDetailsAction.action"
executeResult="true" />
</sx:div>
<sx:div id="div2" label="Library Form" href="%{test2}"
refreshOnShow="false" preload="true">
<s:action name="demo/LibraryFormDefaultAction.action"
executeResult="true" />
</sx:div >
</sx:tabbedpanel>
I have put false in refreshOnShow attribute so the tab is not refreshed once
it gets selected. What i want is to maintain the history of the changes made
to other tabs which were not submitted.
Thanks,
Shoaib Ahmad Gauhar
