Form field validation - best practices
In our application, the implementation for error message handling is: using a HashMap for error messages with the form propertyName as the key. This prevents duplicate messages for form fields. Taking one example use-case: zipCode, rules are: must be numeric, and must be at least 5-digits in length. Debated in our group is the need for having both messages presented to the user if qwe were entered for a zip code. Granted, this simple use case may not be the best example of needing multiple messages. But we feel the implementation should support it. Changing the HashMap key to propertyName+messageName would suffice, but the need for this change is pending our findings on best-practices. I searched the archives for +validation +'per field' with few results that did not really address this question.

RE: problem in Beanutils.copyProperties()
Try writing your own utils class extending BeanUtils. You can either check all input variables for null, or check datatype first, then check for null only on those properties you wish to allow 'null-ok'. You can still take advantage of BeanUtils by calling super.X(property, value), or super(dest, src) on anything that passes your validation. Possibilities are endless. Another option, which I don't like myself, is having a default date in your app new date(0)- defaults to 1974(?), that you can ignore elsewhere in your app (e.g. - put it in your DAO, so it doesn't write the bad date to the DB table, but clears the value first) This second option litters the code with exception handling, which I would only do as a last resort.

DynaForms Radio Buttons
use the Id (userId,accountId)or concatination of Id|someOtherVariable as the value of the Radio button property. Then in your action you would use the value of the radio to perform further processing. In most cases, the rows are simple views of an object. The selection of the row would require you to build a more complex view of the object(built from it's ID) and send you to an edit screen. If you already have the complex model built, you need a rowId as the value, which you would use as the index of the list. Easiest way: String[] rowsSelected = form.get(propertyName); //in the action class String[] rowsSelected = get(propertyName); //in the form Going to an edit Screen? Perhaps you should use javascript to ensure only one is selected.

Tomcat 5 issue
I need to know if Tomcat has a request timeout that can be configured. Looking into the server.xml, I see timeouts related to database connections, and session, and something called tcpSelectorTimeout I have a wierd scenario: Typically, logging massive amounts of data will overburden memory usage and create OutOfMemory exception in the JVM. We have a situation where running in DEBUG mode works where ERROR mode does not. This is backwards to what we are used to seeing. I believe if we up the minutes for our request timeout, we might be able to alleviate this issue. My hunch is that queuing the log.write is circumventing the request timeout; by the time the queue is empty, the objects are built and ready to render the page. In ERROR mode(log4J), the browser just quits after 2 minutes. Nothing in the log looks suspicious. Duane

RE: Conditionally show values in Tile (c:when?)

I believe the scriptlet is evaluated at runtime(server-side). Is it
possible you have a bean property holding this: errmsg 'expected value'
?
tiles:useAttribute id=errmsg name=FieldError scope=page/
However the JSTL is explicitly directed to Page-scope for this. See a
problem?
To address your previos question, I believe Tiles does not impose any
limitation on your JSTL.

Hi all,
I have a tile that shows my default input row in a form. In case that I
put a value in FieldError, I want it to show it the errorMessage in red
color.
So far so good. The values get to the tile (formRow)... and there it's
getting somewhat tricky. After reading a number of explanations, I
understands that struts.apache.org recommends to use JSTL whenever
possible... thus I use the c:when/c:otherwise construct like follows
tiles:useAttribute id=errmsg name=FieldError scope=page/
td
%=errmsg.toString().length()%
%--correctly prints the expected value--%
c:choose
c:when test=${errmsg.toString().length() 0}
font color=#FF
tiles:getAsString name=FieldError/
/font
/c:when
c:otherwise
img src=/img/blank.gif height=1 width=111
%--unexpectedly always shows this--%
/c:otherwise
/c:choose
/td
Substitutes using logic:greaterThat are showing the same strange
behavior...
Any Idea why this happens ? Any Tutorials, I could look up ?

RE: validate() not called haunts
p. Now i have got the debugging working. But
Since debugging is working, try catching a breakpoint where validate is
being called, then step-into...
My best guess is the method signatures need to be verified. INO, are you
overridding validate or overloading? You may be invoking the superclass
validate instead of the intended forms' validate. If all else fails,
place a breakpoint/sys.out in Struts' ActionForm.validate to see if it's
getting there.
Happy debugging,

Subject: validate() not called haunts
Hi,
Thanks for all the help. Now i have got the debugging working. But still
the problem remains, validate() not being called. I tried all
combinations...I made a simple action and form without any business
logic etc...but i dont understand why validate method is being called in
only a single form and not being called for any other forms.
Most weird error.
Even if I call validate from the corresponding action, it does not get
called. However if I rename the validate method by another method e..g
update then I can call the update method from action.
Is there a way that the action errors created can be shown as error by
jsp page ?
Heres the code ;
**action
form.update(mapping,request); // form.validate() doesnt get called so i
renamed
to update()
**form
public ActionErrors update(ActionMapping mapping, ServletRequest
request) {
super.validate(mapping,servlet);
errors = new ActionErrors();
if (nullOrBlank(m_location)) {
errors.add(Location,new
ActionError(errors.location.required));
}
return new ActionErrors();
}
So basically the action class can get the errors, but how should i
display that errors on jsp (This is all because validate() not being
called).

Subject: Validator...the 1001st question...
Hi all,
I'm curious ... shouldn't it be possible to override the default error
message assigned to a validator rule ?
Here's the example:
validator.xml
[...]
field depends=validwhen property=salutation
msg name=testmsg key=error.saluation.makechoice/
arg key=label.salutation position=0/
var
var-nametest/var-name
var-value(*this* != u)/var-value
/var
/field
[...]
validator-rules.xml
[...]
validator name=validwhen
msg=errors.required
classname=org.apache.struts.validator.validwhen.ValidWhen
method=validateValidWhen
methodParams=java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
org.apache.commons.validator.Validator,
javax.servlet.http.HttpServletRequest/
[...]
I understand, that the errors.required is the default msg. And thats
exactly what gets shown in case of an error. Am I stupid or shouldn't it
show error.saluation.makechoice instead ??
scratching his head

RE: Javascript + Struts html:hidden write='true' tag problem
Thanks for your response. In the code in question, disabled is a local
variable passed in as a parameter on the function, and does not refer to
the form properties state. Although, this may lead to a hint of the
'reserved word' behavior I was trying to track. I suspected 'locked' was
the culprit, but this gives me another avenue to test. Thanks!

Duane,
As far as I understand, disabled is a property of the form which
should be denoted as
document.forms[0].disabled
and not just by disabled as you have done in
if(disabled ==true )
change it to:
if( document.forms[0].disabled == true )
and it should work.
This is the reason the if(...) is always evaluating to false (i.e
the 'else' case).

Javascript + Struts html:hidden write='true' tag problem
I have the following Javascript primarily used to manipulate a CSS style
and make a portion of a form visible. In the process, the achor invoking
the JavaScript passes parameters from a table Row(resultset) displayed.
In this Row, I have two bean properties declared as Java type Boolean.
The toString() on the link resolves to 'true'/'false' correctly. I have
placed alert tags in the javascript and have determined that the 'if'
statements are working correctly also. The problem is that the two
properties are behaving differently in the view, for reasons I cannot
pin down. document.forms[0].disabled shows the correct status of the
Row, document.forms[0].locked always shows false.
I suspected 'locked' may be a reserved word, but have rewritten the bean
and supporting code to rename the property, and this has had no effect.
Things that DO WORK: The link is passing the correct values to JS, No JS
error being thrown, as it would if the form property were not found. The
visible, not visible works, also a checkbox instead shows the
appropriate checked/not checked condition, so I can assume a page
refresh is not the issue.
Any other debug tips would be appreciated.
Javascript:
function
PortalFilterForm_AccountDetails(rowId,rewardSummaryId,pin,inUse,disabled
)
{
//alert(rowId = + rowId + \nrewardSummaryId = +
rewardSummaryId + \ninUse = + inUse + \ndisabled = + disabled);
var detailElement = document.getElementById(accountDetail);
detailElement.style.visibility = visible;
var rid = document.getElementById(rid);
rid.innerHTML = rowId;
document.forms[0].rewardSummaryId.value = rewardSummaryId;
document.forms[0].pin.value = pin;
if(inUse == true){
document.forms[0].locked.checked = true;
//alert(evaluated true);
}
else{
document.forms[0].locked.checked = false;
//alert(evaluated false);
}
if(disabled == true)
document.forms[0].disabled.checked = true;
else
document.forms[0].disabled.checked = false;
//document.forms[0].locked.value = inUse;
//document.forms[0].disabled.value = disabled;
// also tried:
//document.forms[0].locked.value = inUse + ;
//document.forms[0].disabled.value = disabled + ;
}
JSP - Note the commented out code does not work (hidden write=true). The
checkbox does work on both.. (Boolean type on both)
( Struts API says HTML:hidden requires String, but Boolean can be cast,
and remember I have one working property, plus one not working ? ? )
