FIFO ordering of ActionErrors
Hi listers,
I have been working on this issue for the last couple of days but haven't
found any satisfactory answers through the usual channels (mailing list
archives, API, and some source code perusal as well).
As I understand it, post struts 1.1, ActionErrors were supposed to keep
their FIFO ordering. I have tried a nightly from 2004-01-27 and just
recently 2004-03-23 and here's what I experience:
* all of my forms extend ValidatorForm
* In one of those forms I override the validate method which first makes a
call to super.validate()
* If the above call returns any errors, I wanted to stick a prefix
(or suffix) message in front of the errors shown by validator. For the
sake of simplicity, the rest of discussion will focus on adding a suffix
message (as its a lot easier to describe how I added the suffix message).
So, instead of seeing the regular (boring :-)) messages from validator
like:
* 'Postal Code' is a required field.
* 'City' is a required field.
the user would instead see:
* 'Postal Code' is a required field.
* 'City' is a required field.
* Invalid and/or incomplete input. Please provide the correct information
as instructed:
Here's a look at the errors object from the debug log before the insertion
of the suffix message.
{
postalCode=[errors.required[Postal Code, null, null, null]],
city=[errors.required[City, null, null, null]]
}
(BTW, to make the message appear before the other ones as a prefix, I had
to create a new errors object and then add the original ones to it).
So the following code line example just tries to add an ActionMessage
with resource errors.validator.prefix [sic] at the end.
So, after making my super.validate() call, I added a call to:
errors.add(ActionMessages.GLOBAL_MESSAGE,
new ActionMessage(errors.validator.prefix));
I would have expected the above line to just add a 3rd property at the
end. Unfortunately, the errors object now looks like:
{
postalCode=[errors.required[Postal Code, null, null, null]],
org.apache.struts.action.GLOBAL_MESSAGE=[errors.validator.prefix[]],
city=[errors.required[City, null, null, null]]
}
(Notice the GLOBAL_MESSAGE property stuck in the middle)
With the result being that the user sees:
* 'Postal Code' is a required field.
* Invalid and/or incomplete input. Please provide the correct information
as instructed:
* 'City' is a required field.
Did I understand the FIFO capability of ActionErrors incorrectly? If this
helps any, postalCode is one of the only few fields that I have discovered
in all of my forms which bubbles up to the top.
Any help is appreciated.
Thanks,

Links within ActionErrors
I know this probably violates some basic guidlines but...
I am trying to display an html link rendered by the message in the
ActionErrors section of a JSP.
My problem is that the '' and '' symbols are being replaced by ' l t;'
and ' # 034;' (their equivelent)
How can I prevent this translation from happening?
Example:
In the applicationresources file we have something like the following:
error.save.dup.link=a href={0}click for details/a
The action class creates the actual link address and adds an actionError as
follows:
tActionErrors.add(ActionErrors.GLOBAL_ERROR,
new ActionError(error.save.dup.link,
iRequest.getRequestURL().substring(0,iRequest.getRequestURL().lastIndexOf(/
)) +
/blah blah blah ));
saveErrors(iRequest, tActionErrors);
In the JSP we have tags to dislay the errors:
logic:messagesPresent
tabletrtd
bspan id=errorsHeaderbean:message
key=errors.validation.header//span/b
html:messages id=error
c:out value=${error}/
/html:messages
/td/tr/table
/logic:messagesPresent
When the error is displayed because the '' and '' signs have been replaced
it just show the text as follows:
a href=http://localhost:8080/blah blah blah click to see /a

redirects / actionErrors
Hi, I am using action errors as a means of passing messages to the request: e.g. in Action, execute method... errors.add(ActionErrors.GLOBAL_ERROR, new ActionError(message.to.user)); saveErrors(request, errors); return mapping.findForward(Constants.REDIRECT_KEY); But if I redirect from this action to another forward that is also an action, the actionError is out of scope. I would be interested to know if (a) this is good practice - to forward to another forward (it seems to work for me) (b) there is an easy way to carry the actionError forward within storing in the session, and saving it in the redirected request. Hope I'm making sense, Thanks, al
Re: redirects / actionErrors
Hi, I don't know if i could understand your doubt (correct me if i'm wrong) but you must forward to your .jsp page and not redirect... If you have a global forward (in your struts-config.xml) like forward name=/my_forward_name path=/my_jsp.jsp redirect=false\ the request will be forwarded to the .jsp resource. But if you have forward name=/my_forward_name path=/my_jsp.jsp redirect=true\ the request will redirected (then you will lose the attributes in your request) mucus snot wrote: Hi, I am using action errors as a means of passing messages to the request: e.g. in Action, execute method... errors.add(ActionErrors.GLOBAL_ERROR, new ActionError(message.to.user)); saveErrors(request, errors); return mapping.findForward(Constants.REDIRECT_KEY); But if I redirect from this action to another forward that is also an action, the actionError is out of scope.

Re: redirects / actionErrors
Ok, but i think you will lose your request attributes (because redirect will generate a new request from your browser)...Session or application attributes will be preserved. mucus snot wrote: Hi, I am intending to use a redirect rather than a forward.

Re: redirects / actionErrors
Struts 1.2 has a feature you can use that allows you to store your ActionMessages in session variables, then have it removed once they're accessed. I haven't used this yet, but you can probably build on this by storing your errors before you redirect, then have them displayed by the resource your redirected to. Another option is the extensions at http://www.rabago.net/struts/redirect which actually adds your messages (error or not) to the url paramters and puts them back on the ActionMessages queue upon redirection. hth, Hubert --- mucus snot [EMAIL PROTECTED] wrote: Hi, I am using action errors as a means of passing messages to the request: e.g. in Action, execute method... errors.add(ActionErrors.GLOBAL_ERROR, new ActionError(message.to.user)); saveErrors(request, errors); return mapping.findForward(Constants.REDIRECT_KEY); But if I redirect from this action to another forward that is also an action, the actionError is out of scope.

ActionErrors deprecated?
While refreshing my memory on the ActionErrors class, I noticed that the metho: void add (String, ActionError) Is deprecated, in favor of: void add(String, ActionMessage) with a note that this (first signature) method will be removed after Struts 1.2. What exactly is this trying to tell us? Are we supposed to drop ActionError entirely in favor of ActionMessage? There's no deprecation note in the description of ActionError.

RE: ActionErrors deprecated?
There's one thing I forgot to mention. That statement I made is for the nightly build/Struts 1.2. ActionError isn't marked as deprecated in 1.1. Are you talking about the ActionForm.validate() method? For the nightly build, yes, that looks about right. The html:errors/ tag in the nightly build doesn't even reference ActionError/s in the code -- it works with ActionMessage/s objects. I'm guessing they can't deprecate ActionErrors yet because it's in validate()'s signature. For errors in your Action class, try Wendy's suggestion. Wendy, are you using that code with 1.1? I haven't tried it yet. Now that I think about it, I'll start asking my teammates to start using these in Action classes. If it works, then better to write new Action classes that way than to add more soon-to-be-deprecated code. --- Slattery, Tim - BLS [EMAIL PROTECTED] wrote: Yes, we're supposed to use ActionMessage and ActionMessages now.

It's the new and improved way to display messages on your pages. html:errors/ sometimes needed html markup on the message resources file to format the messages properly.

I am thinking of using it somewhere else in my app. Thanks for the info I was going through the link provided by you, where the patch for ActionForward is being addressed. Please let me know which build of struts should I use to check the new implementation.

Manjunath, The patch was just submitted and Ted Husted indicated he will look at it, but just because someone submits a patch doesn't mean it gets committed (I would hope not!).

ActionErrors display
Hi, I have been trying to work through the display of ActionErrors - both global and non-global (field level) - such that it would look something like the following HTML sample: html headtitleSearch Form/title/head body PstrongThe following errors have occurred:/strong/P UL LIiA global error has been detected/i/LI LIiLast Name is invalid./i/LI /UL pFields marked with a red background and a img src=https://scgi.ebay.com/saw/pics/sitewide/warning_9x10.gif; width=9 height=10 hspace=3 vspace=2 border=0font face=Arial, Helvetica, Verdana, sans-serif size=2 have failed validation./p form name=search method=POST action=search.do h3Please provide the following search criteria information./h3 pYou must complete all of the fields marked with an asterisk font color=red(*)/font./p pfont color=red*/fontLast Name: input style=background: red type=text name=lastname maxlength=25 size=25 value=Do! title=Last Name is invalid. img src=https://scgi.ebay.com/saw/pics/sitewide/warning_9x10.gif; width=9 height=10 hspace=3 vspace=2 border=0/p pfont color=red*/fontFirst Name: input type=text name=firstname maxlength=25 size=25 value=John/p input type=submit value=Continue /body /html The desire is: 1. All errors will appear in one place - the top of the page. 2. Any field for which validation errors have been detected, would be further flagged in 1 of three potential ways: a. changing the fields background colour; b. marking it with an exclamation icon (thanks to eBay for the quick sample); or c. including the error message (in this case Last Name is invalid.) in the title attribute of the input. #1 is easily achieved; however, I have been struggling with #2 in any form. The html:errors tag makes it very easy to output the message for a specific field, but I cannot seem to find a means to use it to flag that an error has occurred. Any suggestions would be greatly appreciated. Cheers, James THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: ActionErrors display
Looking at the source for the ErrorsTag, it definitely is designed only to output error messages. It seems you could pretty easily subclass ErrorsTag with a tag that uses the presence or absence of an error message for the given property to decide whether to return Tag.SKIP_BODY or Tag.EVAL_BODY_INCLUDE from doStartTag. Then your warning image HTML could be nested inside your jamesBrown:errorsPresent tag. You'll have to decide whether this feature is worth that effort, but there it is. -john.

ConcurrentModificationException on ActionErrors
I have a Struts action that is trying to show all of the errors that might occur from
either or both of two subordinate methods. The
code looks like:
...
ActionErrors errors = new ActionErrors();
ActionErrors errors1 = null;
ActionErrors errors2 = null;
Obj1 obj1 = new Obj1();
Obj2 obj2 = new Obj2();
obj1.method1();
errors1 = obj1.getErrors();
if (!errors1.isEmpty()) {
errors.add(errors1);
}
obj2.method2();
errors2 = obj2.getErrors();
if (!errors2.isEmpty()) {
errors.add(errors1);
}
...
Problem is I get the ConcurrentModificationException when I try and do either of the
errors.add methods above. Methods
method1/method2 are pretty vanilla, just doing some database work and accumulating any
errors in an associated ActionErrors.
I've searched the archives but only found one or two references to
ConcurrentModificationException and they did not involve
ActionErrors. Any ideas or help is appreciated.

I don't know what is causing the exact error from your code snippet, but a
ConcurrentModificationException is thrown when you try to modify a list on which you
have an iterator.

RE: ConcurrentModificationException on ActionErrors
Paul,
Thanks I had seen the exception javadoc. An in one of my subordinate methods I do have
a logging snippet that uses an Iterator to
display ALL of the contents of the ActionErrors. And I imagine that my subsequent use
of the ActionErrors.add(ActionErrors) method
also uses an Iterator to enumerate the ActionError objects. Is there anyway to close
the first Iterator so that it does not cause
this conflict?
Thanks again - Richard

Re: ConcurrentModificationException on ActionErrors
It almost sounds like your code isn't handling errors1 and/or errors2 in a
thread-safe manner. ConcurrentModificationException will be thrown if one thread
is in the proces of iterating over a collection and another thread modifies that
collection. ActionMessages.add(ActionMessages) will iterate over both the arg's
properties and the messages for each property, so there's certainly the
potential for the error you're seeing. Can you provide some more detail on how
your code is organized?
BTW, not sure if it's a c/p error, but you've got:
if (!errors2.isEmpty()) {
errors.add(errors1); // shouldn't that be errors2?
}

Re: ConcurrentModificationException on ActionErrors
Could you show the implementation(s) of your ObjX.getErrors() methods. I'm
guessing there's probably a better way to do what you're trying to do.
It probably has something to do with the implementation of:
http://jakarta.apache.org/struts/api/org/apache/struts/action/ActionMessages.html#add(org.apache.struts.action.ActionMessages)
which calls:
http://jakarta.apache.org/struts/api/org/apache/struts/action/ActionMessages.html#properties()
which returns an Iterator, which, as described below probably throws your
exception.
It sounds like the ActionErrors instance you're adding may be the same one
you're trying to add it to.

RE: ConcurrentModificationException on ActionErrors
Ben,
The implementation is a pretty simple getter. The ActionErrors object is built by
the call to obj1.method1().
/**
* Get ActionErrors object
*/
public ActionErrors getErrors() {
return errors;
}
The actual code for obj1 is very large (1900 lines) and of course 99% is not relevant
to the issue (but which 1% is :) ) so I
hesitate to attach it.
The obj1 and obj2 objects (not their actual names) are actually DAO objects that take
as input a Struts form bean and update and
add/chg/delete the corresponding database object. All of the edit, error and mapping
code is included (generated by XDoclet) so its
huge (actually compiles small, but being generated its quite verbose).
If I cannot figure this out, I will go back to a simpler strategy. I had weanted to
let the user see all errors at once, rather than
showing them some, having them correct them and then showing them more.
Thanks again - Richard

Subject: Re: ConcurrentModificationException on ActionErrors
Could you show the implementation(s) of your ObjX.getErrors() methods. I'm
guessing there's probably a better way to do what you're trying to do.
It probably has something to do with the implementation of:
http://jakarta.apache.org/struts/api/org/apache/struts/action/ActionMessages.html#add(org.apache.struts.action.ActionMessages)
which calls:
http://jakarta.apache.org/struts/api/org/apache/struts/action/ActionMessages.html#properties()
which returns an Iterator, which, as described below probably throws your
exception.
It sounds like the ActionErrors instance you're adding may be the same one
you're trying to add it to.

I don't know what is causing the exact error from your code snippet, but a
ConcurrentModificationException is thrown when you try to modify a list on
which you have an iterator.

ConcurrentModificationException on ActionErrors
31/12/2003 15:36
Please respond to
Struts Users
Mailing List
I have a Struts action that is trying to show all of the errors that might
occur from either or both of two subordinate methods. The
code looks like:
...
ActionErrors errors = new ActionErrors();
ActionErrors errors1 = null;
ActionErrors errors2 = null;
Obj1 obj1 = new Obj1();
Obj2 obj2 = new Obj2();
obj1.method1();
errors1 = obj1.getErrors();
if (!errors1.isEmpty()) {
errors.add(errors1);
}
obj2.method2();
errors2 = obj2.getErrors();
if (!errors2.isEmpty()) {
errors.add(errors1);
}
...
Problem is I get the ConcurrentModificationException when I try and do
either of the errors.add methods above. Methods
method1/method2 are pretty vanilla, just doing some database work and
accumulating any errors in an associated ActionErrors.
I've searched the archives but only found one or two references to
ConcurrentModificationException and they did not involve
ActionErrors. Any ideas or help is appreciated.

Subject: Re: ConcurrentModificationException on ActionErrors
It almost sounds like your code isn't handling errors1 and/or errors2 in a
thread-safe manner. ConcurrentModificationException will be thrown if one thread
is in the proces of iterating over a collection and another thread modifies that
collection. ActionMessages.add(ActionMessages) will iterate over both the arg's
properties and the messages for each property, so there's certainly the
potential for the error you're seeing. Can you provide some more detail on how
your code is organized?
BTW, not sure if it's a c/p error, but you've got:
if (!errors2.isEmpty()) {
errors.add(errors1); // shouldn't that be errors2?
}

RE: ConcurrentModificationException on ActionErrors
Although it's possible to generate that exception from within the same thread,
it's usually triggered by multiple threads accessing the same collection. In
general, if you grab an iterator, then modify the underlying collection, and
then call iter.next(), you'll see that exception. Having multiple iterators
shouldn't be an issue - you don't explicitly close an iterator like a database
connection. It will be GC-ed just like any other object. The problem really
boils down to modifying the backing collection while iteration is in progress.
By in progress, I mean doing something like calling iter.next(), not that
there's just an iterator instance lying around.

Re: ActionErrors without resource bundle.
Hi, I don't think it's possible. I've been looking at issues with ActionErrors and ActionMessages and I could not find any constructors that wuld let you pass a message String rather than a key to use in a resource bundle. I have the problem where I an using more than one file with resources. To do this I've had to have multiple html:message tags in the web documents. I've been getting the impression over the last few months that there are a number of areas in struts that have only been coded with the minimal functionality as assumed by developers who wish to do things in a certain way. I.e. if you want to do things slightly differently you either can't or you will have to write your own JSP tags to do it. I would suggest that if you really need to do this, then write your own JSP tag to replace html:errors. I would probably make it look for a LinkedList of text strings or something in a bean and display them. Then you could populate this list in any fashion you liked. If you haven't written a tag before it's not difficult to do once you understand the bits you need. cio Derek.

No getProperties() on ActionErrors?
Hi all,
I have the following problem: I want to access ActionError objects using
the EL language in a JSP page like this (for a reason I don't want to
work with the html:error taglib):
c:forEach
items=${requestScope}['org.apache.struts.action.ERROR'].properties
var=error
divc:out value=${error}//div
/c:forEach
My guess is that this doesn't work because the ActionErrors class has a
properties() method and not a getProperties() method. Does anyone know a
way to iterate over the ActionError objects in the ActionError object
using the EL language?
Thanks and regards,

Note that when you hit the Back button on a page not cached and retrieved by

Thanks for any hint...

ActionErrors are not displayed after page is refreshed.
Hi,
I have a jsp in which i have written the following code to display the errors,
logic:messagesPresent
p CLASS=errorsHeader
bean:message key=errors.validation.header/
/p
html:messages id=error
lic:out value=${error}//li
/html:messages
hr SIZE=1 NOSHADE WIDTH=620 ALIGN=left
/logic:messagesPresent
Along with that i have a code to at the bottom of page to go to top of the pages as
follows,
TD ALIGN=center COLSPAN=10A HREF=#tophtml:img
page=/images/IcoGoTop.gif width=17 height=17 border=0 alt=Top of
Page/html:img/A
/TD
Now the problem i am facing is that when i click on top image the page gets refreshed
and errors messages goes off.
Is there any way i can provide a code to goto top along with keeping the error
messages.
Thanks and Regards
Deepak.

RE: ActionErrors are not displayed after page is refreshed.
Hi,
I think the problem is that you define a new Event when going to top of your
page. Try this: make a simple javascript, that sets the focus to an element
at the top of the page (that leads the browser to go to the focused
element and therefore to the top of the page), then your Error-Messages
should remain.

Christine

ActionErrors configuration
Hi, I am trying to configure my app so that when some of the text fields are not populated, I show errors and redisplay the same page. The configuration I have is: action path=/systemDetails type=com.paycycle.profile.actions.SystemDetailsAction name=systemDetailForm scope=request input=/systemDetails . /action When I try to run the app with this configuration and there are errors, I get: The requested resource (/profile/systemDetails) is not available. Can you help me out here? Thanks, Ramesh.
Re: ActionErrors configuration
You should have the name of the jsp with the form (or possible the action that leads to the form page, with the .do extension) as the input. So your action would have input=/systemDetails.jsp if that is the name of your jsp page.

RE: ActionErrors configuration
Hi That sound like another problem than what you wrote about first :-) But anyway ActionErrors has both an add(String, ActionMessage), defined in the superclass ActionMessages, and an add(String,ActionError) , defined in ActionErrors class which just calls the superclass version. That call works fine sinse ActionError inherits from ActionMessage.

Hi Keld,
I just discovered that I was in fact not showing any of my validator
errors. It just goes to show that having javascript validation enabled
means I had assumed it was working fine for x weeks - but anyway, I
worked out I needed this taglib to show them:
html:messages id=validatorMsgs
message=false
header=errors.header
footer=errors.footer
c:out value=${validatorMsgs} /
/html:messages
Since I'm using Tiles though I only had to add this in one place and now
it's fine again. (Guess I can turn javascript back on in my browser...)

ActionErrors/ActionMessages
I'd like to emphasize the importance of a mail recently added to the newsgroup regarding the use of ActionErrors and/or ActionMessages. The Validator uses the ActionErrors queue, so even if you'd like to use the new ActionMessages queue you'd hesitate to do so since this forces you to manage two queues in your jsp-pages. So when ActionErrors(s) gets deprecated (in version 1.2?) then what do you do? I'd be very interested in an answer on this topic. Thanx.

Re: ActionErrors/ActionMessages
Let me elaborate a little: As I understand it the Validator uses the ActionErrors queue. This means that I'll have to code this in my jsp-page: html:messages id=error message=false BRbean:write name=error/ /html:messages If I use the ActionMessages queue for my own validation - or error handling in general - in my Action classes, then I'll also have to code this in my jsp-pages: html:messages id=error message=true BRbean:write name=error/ /html:messages So the net result is that my jps-pages becomes more clumsy.

This works to display the Validator messages and errors from the Actions
if you save them like request.setAttribute(Globals.MESSAGE_KEY, messages)
html:messages id=errorMsgs
message=true
property=${GLOBAL_ERROR}
header=errors.header
footer=errors.footer
c:out value=${errorMsgs} /
/html:messages
I'm afraid I don't remember the finer details but this will show both
yours and Validator's errors.

errors and exception in ActionErrors
I would like to put in the ActionErrors object regular errors that may happen and also
an exception without loosing the previously stored errors.
These are the steps I am taking and the results I am getting:
1. Errors occur so I add them to the ActionErrors with the GLOBAL_ERROR property:
ActionErrors myActionErrors = new ActionErrors();
myActionErrors.add(ActionErrors.GLOBAL_ERROR, new ActionError(test.error));
myActionErrors.add(ActionErrors.GLOBAL_ERROR, new ActionError(test.error2));
saveErrors(request, myActionErrors);
2. An exception is thrown:
catch(Exception e)
{
throw new TestException(this was a test Exception,e);
}
3. The exception is handle by the ExceptionHandler defined in the config file:
!-- Test Exception Handdler --
action path=/test
type=edu.miami.BaseAction
exception
type=edu.miami.exceptions.TestException
key=test.exception
path=/testExceptionError.jsp /
forward name=success path=/testExceptionNoError.jsp /
/action
4. When I try to output the information in the JSP using the errors tag only
information about the exception is diplayed. test.error and test.error2 seems as if
they were gone.
html:errors /
How can I keep both, errors and the exception in hte ActionErrors object, or
how can I access them if they are there already?
Also I would like to find out under which property is the exception information kept
in the ActionErrors because when I try to output
html:errors property=%=ActionErrors.GLOBAL_ERROR% /
the exception information is not shown, so it must be under some other property.
Thanks

Hi Jorge,
I have no expert knowledge of the workings of ActionErrors struts
controller, in fact until you mentioned it, I was unaware that you could
map an exception to a JSP via the action mapping like that.
However you could easily find out what happens to your exceptions by
debugging in the JSP to see what is in there. Perhaps struts simply
overwrites any object that is already stored in the request under that key.
And the exceptions may be held in the collection under the
ActionMessages.GLOBAL_MESSAGE property.

Only ActionError is deprecated right now. However, most of the references

ActionErrors is still around because it's in the ActionForm.validate()

for a Struts 1.2 app.
Eventually, we'll use Commons Resources' Message and MessageList

I looked at the validate method of DynaValidatorForm, and I'm confused.
It doesn't seem to do what it says it does. AFAICT, this method
*always* returns the empty ActionErrors object that's created with:
ActionErrors errors = new ActionErrors();
If errors ARE found, they're never put into that ActionErrors object,
they're stored in the protected ValidatorResults object.
/**
* Validate the properties that have been set from this HTTP
request,
* and return an codeActionErrors/code object that encapsulates
any
* validation errors that have been found. If no errors are found,
return
* codenull/code or an codeActionErrors/code object with no
* recorded error messages.
*
* @param mapping The mapping used to select this instance.
* @param request The servlet request we are processing.
* @return codeActionErrors/code object that encapsulates any
validation errors.
*/
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
this.setPageFromDynaProperty();
ServletContext application = getServlet().getServletContext();
ActionErrors errors = new ActionErrors();
Validator validator =
Resources.initValidator(mapping.getAttribute(), this,
application, request, errors, page);
try {
validatorResults = validator.validate();
} catch (ValidatorException e) {
log.error(e.getMessage(), e);
}
return errors;
}
Can someone who knows what's happening with ActionError/ActionErrors
please post a summary?

ActionError and ActionErrors are deprecated, yet the validate method of
DynaValidatorForm still returns an ActionErrors object.
I looked at the validate method of DynaValidatorForm, and I'm confused.
It doesn't seem to do what it says it does. AFAICT, this method
*always* returns the empty ActionErrors object that's created with:
ActionErrors errors = new ActionErrors();
If errors ARE found, they're never put into that ActionErrors object,
they're stored in the protected ValidatorResults object.
/**
* Validate the properties that have been set from this HTTP
request,
* and return an codeActionErrors/code object that encapsulates
any
* validation errors that have been found. If no errors are found,
return
* codenull/code or an codeActionErrors/code object with no
* recorded error messages.
*
* @param mapping The mapping used to select this instance.
* @param request The servlet request we are processing.
* @return codeActionErrors/code object that encapsulates any
validation errors.
*/
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
this.setPageFromDynaProperty();
ServletContext application = getServlet().getServletContext();
ActionErrors errors = new ActionErrors();
Validator validator =
Resources.initValidator(mapping.getAttribute(), this,
application, request, errors, page);
try {
validatorResults = validator.validate();
} catch (ValidatorException e) {
log.error(e.getMessage(), e);
}
return errors;
}
Can someone who knows what's happening with ActionError/ActionErrors
please post a summary?

Well, this is not true.
According to the code, the errors object gets passed to the initValidator( )
method which returns a Validator object, and the validator object than calls
the validate() method. Since Java pass by reference, the error object could
be changed in the initValidator() method as well as in the subsequent
validate() method.

setting an ActionErrors object for a form outside a validate method...
My Action class does some processing that involves going to the database. This work could throw a SQLException and I want that to generate an error message for the user. However I don't want to do this work in the validate method, only to have to do it again in the execute method (besides SQLExceptions can be non-determinate so this wouldn't solve the problem anyway). So, my question is how can I add an ActionErrors object to my form from within the execute method so I can send the user back to their requesting page with an intelligent and well formatted message?

RE: setting an ActionErrors object for a form outside a validate method...
Hi Alan,
Here are the basics:
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {
ActionErrors errors;
ActionError error;
//create the errors
errors = new ActionErrors();
... do your validation, and if error
//create the error
error = new ActionError(error.resource.key);
//add it to the errors (global or form field name based) this
uses global
errors.add(ActionErrors.GLOBAL_ERROR, error);
...perform rest of method
if (errors.isEmpty() == false) {
//save the error
saveErrors(request, errors);
//go back to same page
return mapping.getInputForward();
}
// Forward control to the specified success URI
return (mapping.findForward(success));
}
Hope this helps.
Chuck

ActionErrors
Hello, This works fine: errors.add(ActionErrors.GLOBAL_ERROR,new ActionError(errors.createkunde.float)); but i want to define the message at runtime, i want to put a string into the ActionError that is not defined in .properties file. Is that possible ? if yes, could u give me a example ? thnx for help - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: ActionErrors
Hi,
You can use the placeholder ({0}, {1} ..) feature in message resource
something like this:
In property file:
errors.your_runtime_msg.key = {0}
In Action or form bean:
new ActionError(errors.your_runtime_msg.key, your runtime message,
blah, blah..);
your runtime message, blah, blah.. will replace {0}

Re: ExceptionHandler storing ActionErrors in session
When the declarative exception handling was introduced, I was very concerned about the scope attribute in the ExceptionConfig. It is a redundant attribute if we obey the following rules: 1) All exceptions that could reach to the exception handler should be fatal errors. 2) Fatal errors should be consumed and/or logged in the current thread. The ErrorsTag, MessagesTag, and utility classes were correctly designed to handle request scoped ActionErrors. And the rules are consistent with the servlet engines' error handling mechanism: Any system errors will be output and/or logged in the current thread. Further more, any fatal/system errors from EJB and database must be reported during one invoking method (also in one thread). So in 99% use cases, you do not need to store ActionErrors in the session scope. If the scope attribute was removed, then some bug reports regarding to the exception handling would not be there. Forgetting about session is the *cleanest* solution from my point of view. If the 1% users REALLY want to store ActionErrors in the session scope, they could extend the base exception handler class with the following questions to be answered: 1) When an object is stored in a session, the object should serve some purposes across request threads. If fatal errors do not get handled in the current thread and stored in the session, which later request thread will take care of them? 2) If non-fatal errors are stored in a session and some later request threads may be interested in the non-fatal errors and make decision based on them, then consider do the non-fatal *errors* really qualify as errors? In other words, should they be caught or processed within the Action.execute() method and stored as business objects? It is very likely to over kill a problem if session scoped ActionErrors are used. It only gives you more troubles than problems solved.

Re: ExceptionHandler storing ActionErrors in session
I don't believe there is currently a way to remove messages from the session. How would Struts know when to remove them? I have written a small subclass of ActionMessages that only returns its messages once. This allows me to store messages in the session without them being displayed multiple times. You're not the first person to need this feature so maybe it's time to float the subclass idea on struts-dev (unless there is a better way).
