Re: [S2] Getting the AJAX Form Validations to work

2007-03-13 Thread Binil Thomas


Hi all,

I got it working!

I had to add a validate=true attribute on the s:form/. With that added,
the form was trying to make an AJAX request onblur. But I got a JS error in
FB:
element.form.attributes['name'] is undefined.
Debugging a bit, I figured that the JS figures out the validation action to
invoke on the server from the name attribute of the form. I gave the form a
name (name=myform). Now the AJAX request was made, but DWR was throwing up
some errors on the server-side.
SEVERE: Error while trying to validate
There is no Action mapped for action name myform. - [unknown location]
True, there is no action with the name 'myform'. I changed the name of the
form to the action name as it all started working as expected!
s:form method=post theme=ajax validate=true name=show
s:textfield label=Name name=name/
s:textfield label=Age name=age/
s:submit value=Submit/
/s:form

I copied the evaluated JSP into an HTML page, and debugged it. I was able to
remove all JS errors in FB by:
1) Commenting out a script language=JavaScript type=text/javascript
src=/validations/struts/simple/dojoRequire.js/script added by
thes:head theme=ajax/ tag.
2) Commenting out a dojo.require(dojo.widget.html.Tooltip) line added
by, I think, the s:form/ tag. I think Dojo guys have renamed the widget to
dojo.widget.Tooltip since 0.3.

With these changes, I was able to remove every JS error in FB. I now get
some Dojo deprection warnings though.
DEBUG: DEPRECATED: dojo.style replaced by dojo.html.style -- will be
removed in version: 0.5
DEBUG: DEPRECATED: dojo.animation.AnimationEvent is slated for removal

 Also, on both FB and the page, I see the error:
 Could not load 'dojo.widget.html.Tooltip'; last tried '__package__.js'
 (I have enabled Dojo debug now). I think the Dojo widget is called
 dojo.widget.Tooltip.
 
 When the form first shows up I see the field error message for 'name'
 field. When I fill out the field and tab out of it, no AJAX request is
 send to the server (I am assuming that the expectation is that the form
 gets validated at the server via an AJAX call onBlur).
 
 When I click submit, an AJAX request is send and the server responds with
 the HTML page for the action; but nothing happens to the page.

DispachAction - does not contain specified method

2007-03-13 Thread Nitin Ahuja


Hi,

I am using DispatchAction as my base action class.

when submit url http://.../myAction.do?action=view; and there is no
view method defined in my action class, then it throws following
exception.

Is there any way to call a default method  when the method view does
not exists ?
Or how can I redirect or forward the request to a default page ?

[s2] newbie - setting multiple values in an action

2007-03-13 Thread Martin Fanta

Hi all,

I started playing around with Struts 2.0.6 on Saturday. All went well until
I've run into the need to call an Action setter for a list of strings
submitted from an html form (will switch to dates later, but I want to solve
the multiple aspect first).

I have a jsp with this body:

s:form action=Process
  s:iterator value=dates status=day
s:textfield label=%{top} labelposition=left 
name=days[%{#day.index}]/
  /s:iterator
  s:submit/
/s:form

It is meant to display a label and an edit box for each of the dates from the
'dates' list. The 'dates' is a list set in the prepare action and it is
displayed correctly - here's the rendered html (re-formatted to make it
readable):

form id=Process name=Process onsubmit=return true;
action=/wp/Process.action method=POST
  table class=wwFormTable
tr
  td class=tdLabellabel for=Process_days_0_
class=label13.3.07:/label/td
  tdinput type=text name=days[0] value= id=Process_days_0_//td
/tr
tr
  td class=tdLabellabel for=Process_days_1_
class=label14.3.07:/label/td
  tdinput type=text name=days[1] value= id=Process_days_1_//td
/tr
tr
  td colspan=2div align=rightinput type=submit id=Process_0
value=Submit//div/td
/tr
  /table
/form

The ProcessAction code:

public class ProcessAction extends ActionSupport {

  private ListString days;

  @Override
  public String execute() throws Exception {
System.out.println(ProcessAction.execute());
return SUCCESS;
  }

  public ListString getDays() {
return days;
  }

  public void setDays(ListString days) {
System.out.println(ProcessWeightsAction.setDays());
System.out.println(days.size());
  }
}

What I want to achieve is let Struts call the setDays() with a List of two
values filled in by the user in the html form.

The reality is the setDays() is called twice, but in both cases, the days list
is empty (The user has filled in both text values).

What am I doing wrong? Also, I have browsed through the docs on the struts
website, but did not find anything explaining how this can be done. Can you
please point me to the right document if it exists?

Thanks in advance.

[struts faces] How do i set default values?

2007-03-13 Thread David Delbecq

Hello,

i am trying to convert some struts form to be JSf compatible using
struts faces. However, there are a few problems with initialization for
form.

I have this:
html:form action=/search.do acceptCharset=UTF-8 styleClass=search
html:hidden property=scope value=${param.searchScope}/
html:hidden property=requestedNodeResults value=15/



According to struts faces docs, i need to use the corresponding JSF tag:
h:inputHidden id=scope value=#{myForm.scope}/
h:inputHidden id=requestedNodeResultas
value=#{myForm.requestedNodeResults}/

However, you all can guess my problem, where do i put the 2 default
values for form: '${param.searchScope}' and '15'

According to myfaces mailing list, i should do this in the managed bean
definition. However, there is no managed bean definition in struts faces.

Any suggestion? What am trying to do is incorporate existing struts
forms inside a JSF page. We would like to avoind a immediate complete
rewrite and have a temporary migration solution...

Re: DispachAction - does not contain specified method

2007-03-13 Thread Mark Shifman


You should look at the source
http://svn.apache.org/viewvc/struts/struts1/trunk/extras/src/main/java/org/apache/struts/actions/DispatchAction.java?view=markup
and the javadoc
Method which is dispatched to when there is no value for specified 
request parameter included in the request. Subclasses of 
DispatchAction should override this method if they wish to provide 
default behavior different than throwing a ServletException.


overriding unspecified should do the trick

*protected* ActionForward unspecified(ActionMapping mapping, ActionForm 
form,
HttpServletRequest request, HttpServletResponse response)
*throws* Exception {
String message =
messages.getMessage(*dispatch.parameter*, mapping.getPath(),
mapping.getParameter());

log.error(message);

*throw* *new* ServletException(message);
}

If you feel strongly about this, please create a JIRA issue for possible
enhancement. You may have a good idea worth investigating :)


Part of the problem with the population is that most of the code is
burried in static RequestUtils methods - making providing different
behaviours difficult. I did some work for Struts 1.3 to refactor that
back into the Commands - with the BeanUtils populate being called from
the Command rather than a static request utils method. I think that
would be a first step for solutions to these kind of issues

https://issues.apache.org/struts/browse/STR-2772

Although that issue talks about multipart handling - it also
introduces a populate() method in AbstractPopulateActionForm that
calls BeanUtils populate() directly

Re: [s1] Filters: distinguishing between user-requests and redirects

2007-03-13 Thread Tamas Szabo


Yes, setting the dispatcher will work just for ignoring the forwards,
it won't work for redirects.
You can check for attributes as Paul suggests, but setting the
dispatcher seems to be easier if you have a servlet container
supporting 2.4.

You'll have to handle redirects in another way though.
A simple solution would be to remove the time of the last request from
your list if you return a redirect to the user.

HTH,

Tamas


On 3/13/07, Paul Benedict [EMAIL PROTECTED] wrote:

There is no technical difference between a user request and a redirect,
because the redirect causes a second user request.

If you're interested in knowing whether the action is being called as a
forward, there are standard request attributes which the Container sets.
For a forward it is javax.servlet.forward.request_uri and for an
include it is javax.servlet.include.request_uri

Tamas Szabo wrote:
 Have a look at the documentation of the dispatcherType at
 http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd.

 Then you can use dispatcher elements in your filter mappings
 (filter-mappingType in the same xsd) to fire your filter just for
 requests but not for forwards.

 I pressume that by internal redirects in your initial mail you mean
 forwards. Is this true?

 Hope this helps,

   * On each new request, a filter compares the current time with the

   Therefore my question:  Is there a simple straightforward way,

   redirection from ActionMapping to ActionMapping)?

Validation Framework

2007-03-13 Thread Balazs Michnay

Dear Struts Users,
 
I'm relatively new to Struts and am trying to get the Validation Framework 
working without success. I've read several tutorials and articles on using it, 
but it just doesn't want to work. I'm using NetBeans 5.5, so that I can use 
Struts 1.2.9.
Having set everything, I get no error messages from the Sun Java Application 
Server 9, it just simply does not do any validation. It skips the validating my 
form and forwards me to the JSP page that should open only on successful 
validation.
I don't attach the sources, because the zip file is too big, but I share it 
with you:
 
http://www.inf.u-szeged.hu/~michnay/struts/SZTGKR.ZIP
 
My form should only validate a textarea html control.
Do I need to do any special settings in NetBeans or do I miss some settings?
 
Since it's been about 4 days I'm trying to get it working I'd be grateful if 
someone would please take a look at my form and my validation settings.
 
Thanks for your reply,
 
Regards,
 
  michnay

Re: Validation Framework

2007-03-13 Thread Mike Baroukh

I'm still using struts 1.1 and your struts config/form is really
different from what I used to do.

But, in struts 1.1, we had to add
validate=true
in the struts-config on the action ...

your struts-config doesn't have any.

Maybe ...
