[struts-tiles]: ControllerSupport doesn't support Struts 1.1 controllers

   Summary: [struts-tiles]: ControllerSupport doesn't support Struts
1.1 controllers
   Product: Struts
   Version: 1.2.4
  Platform: Other
OS/Version: Other
Status: NEW
  Severity: Normal
  Priority: Other
 Component: Tiles framework
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]


The delegate in ControllerSupport from perform() to execute() ist the wrong
direction.
Struts 1.1-controllers implement the perform()-method because this method is
called by the framework. If have these old controllers with Struts 1.2 running,
the execute()-Method of ControllerSupport is called - but this method is empty.
But it should delegate to perform().
It doesn't make sense to let perform() delegate to execute() because nobody
calls perform in Struts 1.2.

Thanks Lars

Re: Problem related to Struts-tiles

2004-09-30 Thread Cedric Dumoulin
 Hi,
 Such question should be post in the struts-user mailing list :-).
 Tiles is a framework that build pages by assembling fragment or 
tiles on the server side. When you request a page made of tiles, the 
server return the entire page, not a particular tile.
 If you want only  a particular area of your page to be updated, you 
need to use frames (interpreted on the client side). Tiles and frames 
can be mixed, but you need to manage the frame yourself. Tiles can't do 
it for you.

 Hope this help,

Now when  in my first definition i have one menu.jsp on clicking on that 
menu i call extended definition.
Now problem it refresh the entire page instead of body page.

I want only body content should refresh rest header,footer and menu should 
remain like this just like when we use frames.

kindlly suggest what should i do.

Greeting Cedric:
It has been a long time to see you again on the list. I wonder if you 
have some time to make tiles work better with faces. Here is what I have 
tried faces and tiles without struts (so no plug-in):

1) If i load TileServlet as instructed, the log said tile factory has 
been successully loaded, but somehow the definition factory is not 
loaded. Hence tiles definitions defined in tiles.xml are not available. 
This was done with Faces latest RI.
2) I try tiles with myfaces, i got the same  issue about definition 
factory. However, if i  define tile definition in a page, it works in 
myfaces but not in RI.

I hope you or someone else can give a definitive instruction.

New Page:

There are two frequent issues the confront people when dealing with populating a 
collection of beans in an ActionForm.

 * How can I generate the appropriate html using the struts taglibs?
 * I have a request scoped ActionForm and am getting an index out of range error 
when I submit the form - what do I do?


The ''Indexed Properies'' section below deals with generating the html and the ''Lazy 
List'' section shows possible solutions for avoiding the index out of range error.

== Indexed Properties ==

Struts html tags have an ''indexed'' attribute which will generate the appropriate 
html to populate a collection of beans when the form is submitted.

For example the following jsp...

{{{
   html:iterate name=skillsForm property=skills id=skills
   
   html:text name=skills property=skillId indexed=true/

   /html:iterate
}}}

...will generate the following html

{{{
input type=text name=skills[0].skillId value=.../
input type=text name=skills[1].skillId value=.../

input type=text name=skills[n].skillId value=.../
}}}

When the form is submitted BeanUtils will first call the getSkills(index) method to 
retrieve the indexed bean followed by setSkillId(..) on the retrieved bean.

== Lazy List Behaviour ==

A common problem with indexed properties, is that people then get index out of range 
errors with ActionForms that are in Request scope. The indexed property (List or 
Array) needs to be able to automatically ''grow'' during the ActionForm population 
process. The key to achieving this is in the get(index) method.

The following sections show three examples of how to achieve lazy list processing.


=== Hand Cranking lazy List in the ActionForm ===

{{{

  public class SkillActionForm extends ActionForm {

  protected List skills = new ArrayList();

  public List getSkills() {
  return skills;
  }

  public void setSkills(List skills) {
  this.skills = skills;
  }

  public SkillBean getSkills(int index) {

  // automatically grow List size
  while (index = skills.size()) {
  skills.add(new SkillBean());
  }

  return skills.get(index);

  }

  }

}}}

=== Using Commons Collections for lazy Lists ===

Commons collections have a lazy list decorator which automatically grows the list when 
the get(int) method is called. In the example below the ActionForm implements the 
Factory interface, providing the create() method to populate an entry in the List.


{{{

  import org.apache.commons.collections.Factory;
  import org.apache.commons.collections.list.LazyList;

  public class SkillActionForm extends ActionForm, implements Factory {

  protected List skills = LazyList.decorate(new ArrayList(), this);

  public List getSkills() {
  return skills;
  }

  public void setSkills(List skills) {
  this.skills = skills;
  }

  public SkillBean getSkills(int index) {
  return skills.get(index);
  }

  // 'Factory' method for LazyList
  public Object create() {
  return new SkillBean();
  }

  }

}}}

=== LazyDynaBean / LazyValidatorForm ===

'''N.B.''' Solutions here require '''Struts 1.2.4''' and '''Bean Utils 1.7.0'''

[http://jakarta.apache.org/commons/beanutils/commons-beanutils-1.7.0/docs/api/org/apache/commons/beanutils/package-summary.html#dynamic.lazy
 LazyDynaBean] in [http://jakarta.apache.org/commons/beanutils/ Commons BeanUtils] has 
the ''lazy'' List type processing. 
[http://www.niallp.pwp.blueyonder.co.uk/#lazydynabean LazyValidatorForm] is built 
using the BeanUtils LazyDynaBean and can be used by simply configuring it through the 
struts-config.xml.


{{{

  form-beans

 form-bean name=skillForm type=org.apache.struts.validator.LazyValidatorForm
form-property name=skills type=java.util.ArrayList/
 /form-bean

  /form-beans 

}}}

In fact using Arrays (rather than Lists) a LazyDynaBean can be used directly, in the 
following way:

{{{

  form-beans

 form-bean name=skillForm type=org.apache.commons.beanutils.LazyDynaBean
form-property name=skills type=myPackage.SkillBean[]/
 /form-bean

  /form-beans 

}}}

Struts 1.2.4 will ''wrap'' the LazyDynaBean in a BeanValidatorForm automatically.

Opening it up for debate...

2004-09-30 Thread Frank W. Zammetti
I came across something yesterday that might be good fodder for a debate...
Consider a simple login page.  You submit the typical form with a userID 
and password.  Your ActionForm performs a validation to be sure they 
filled in both fields and returns errors if any validation fails. 
Simple enough.  You do the usual html:errors/ to display the errors.

Now... Presumably most of us would now do the AUTHENTICATION from an 
Action (well, delegated of course), as opposed to doing it from the 
validate() method (I wouldn't view that as correct myself).  Let's say 
the user is not authenticated (bad password perhaps)... So you forward 
to a failure forward, but what about displaying an error message to 
the user?

I imagine the typical thought is to put a message in a request attribute 
and do a bean:write to display it (with ignore=true probably), or 
maybe more properly set some attribute of the form.

So, here's my point... We have in the JSP an html:errors/ tag to 
display VALIDATION errors, but we also have a bean:write/ to display 
the AUTHENTICATION errors.  Is that optimal?  Why can't we do it with 
one line (or can we?  I don't mind learning something new!)

My thought is that maybe it would be appropriate to handle BOTH these 
situations by returning an ActionErrors collection.  Ok, fine, we can 
insert it into request in the Action manually, but that's not a good 
idea because the attribute name might change down the road. 
High-coupling and all that jazz.

What to do?  Well, the first question is, does anyone agree that it 
makes some sense to handle both situations with ActionErrors, and 
thereby only have a single line in the JSP to display both types of 
errors?  If not, ignore the rest of this.

If you agree with that though, here's my suggestion... What if execute() 
in the Action returned an Object, and the object either implements an 
empty ActionForwardResult interface or an ActionErrorsResult interface 
(I just made those up of course), and that can be determined, the object 
casted and acted upon either as the usual ActionForward or the same way 
an ActionErrors is treated from validate() in the form.

What does everyone think?  Am I making a big deal out of the arguably 
minor inelegance of two error display lines in the JSP, or is this 
possibly a real issue to deal with?  Even if you don't view it as a 
problem, might this change result in a bit more flexibility that might 
be good, or would it be breaking some architectural rules (I'm a bit 
mixed on that last point frankly).  Thanks all!

Re: Opening it up for debate...

2004-09-30 Thread Niall Pemberton
First I have to say, that I use container managed security for logon -
rather rolling my own with an Action.

Having said that I don't really see what the issue is - just use the same
error mechanism that the validate() method uses - create an
ActionMessages/ActionErrors object, stick the key to the authentication
error in it, save the errors under the standard key and return to the input
forward.

In Struts 1.1 it would be something like the following in the Action's
execute method...

  // do authentication
  boolean authentic = authenticate();
  if (!authentic) {
   ActionErrors errors = new ActionErrors();
   errors.add(logon, new ActionError(authenticate.error);
   saveErrors(request, errors);
   return getInputForward();
  }


In Struts 1.2.4 it slightly simpler...

  // do authentication
  boolean authentic = authenticate();
  if (!authentic) {
   getErrors(request).add(logon, new
ActionError(authenticate.error);
   return getInputForward();
  }

Another approach which I have used is to consider an authorization 
failure a business exception and throw an 
UnauthorizedUserException which can then be mapped using Struts 
declarative exception handling to look up the appropriate message 
(based on the exception handler config's key property) and deliver 
a usable message to an Error JSP.

But now that you know about saveErrors (and don't forget 
saveMessages), you probably don't need yet another solution!

I actually have to plead ignorance on that... In all honesty, I haven't 
looked over the sample apps as much as I probably should... I'm one  of 
those people that prefers to just jump in, start coding something and 
figure it out as I go.  Plus, I don't generally like looking at other 
people's code, it usually winds up taking more time and effort to figure 
it out than just working out the solution myself.

Here however is a situation where looking at the samples would have been 
very beneficial, and saved a little bit of traffic on the list.  Simply 
put, my bad :)

html:form focus generates non-XHTML

   Summary: html:form focus generates non-XHTML
   Product: Struts
   Version: 1.2.4
  Platform: PC
OS/Version: Windows NT/2K
Status: NEW
  Severity: Normal
  Priority: Other
 Component: Custom Tags
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]


The generated javascript when using 
html:form focus=username ...etc
is not encased in !-- XML comment tags --
Because this particular javascript contains  the document is no longer 
XHTML compliant.
This is the case even when you have html:html xhtml=true and html:xhtml/ 
in the JSP.
Note, this is actually happening inStruts 1.2.2 but wasnt an option on the bug 
reporting page.
