Struts2 s:form to html form changes id attribute

[webmeiker]

Hi,

Does somebody know what could be happening here?



I have exactly same Struts2 web app deployed in two Tomcats but  tag
behaves strange in one of them.



Lets explain myself…



The next line of code in my JSP:







…generates correct html form code in ‘A’ environment:







…BUT generates wrong html markup in ‘B’ environment, in concrete value of
‘id’ attribute should be ‘anunciosListar’:







Why ‘id’ and ‘name’ attributes where interchanged in form markup of scenario
‘B’?


Thanks!!

Re: Parameter manipulation

[Steven Yang]

is your user object initialized when the param interceptor is run?

here i might be wrong, but what i know is if your object is initialized then
Struts or OGNL will call getUser().setEmail(...)
otherwise create a new User then setEmail then setUser
then the second case should fail for you

again, i might be wrong on the behavior

Great news for Struts2 developers.
As far as I know, there is no good open source Struts2 plugin for Eclipse.
MyEclipse provides such one, but it is an commercial product, you need a
subscription.

NetBeans has a good plugin for Struts2 development,
http://nbstruts2support.dev.java.net.

Kind regards

Re: Problem with action mapping

[Dave Newton]

Older Struts/Tiles was notorious (at least in my experience) for swallowing
exceptions whole. My first guess is that something is broken in one of your
JSPs used by the tile.

That's one good reason not to use such old technology for new development:
you lose the benefits of hundreds of thousands of man-hours of experience
generally used to create better, more robust platforms.

Re: Problem with action mapping

[Anjib Mulepati]

There was space at the beginning. That is solved. I'm getting something 
but not whole page just logo and header.
I though name should be body in tiles def file. so I change all to bosy 
as tiles.jsp has attribute="body"


Still same problem.

Convention Plugin, Inheriting from existing projects action

[Arne Stabenau]

Hello,

We are developing here a fairly generic web tool, which for many of our projects
we just want to customize a little. We are using the convention
plugin, since I have
a little dislike of XML config files and want to keep them to a minimum.

Ideally I would like a way to just include the base project into my
classpath and when
I want to customize an action, just subclass it and implement either a
new method
for the action or overwrite some method in the original action to do
the customization.

Well, I tried this and sometimes the subclass is used as action,
sometimes the original,
and I can't really figure out why is that. I was expecting an error
message for re-using
the same action-name (actually a warning log entry).

-- from convention plugin ---

       //check if an action with the same name exists on that package
(from XML config probably)
700        PackageConfig existingPkg =
configuration.getPackageConfig(pkgCfg.getName());
701        if (existingPkg != null) {
702            // there is a package already with that name, check action
703            ActionConfig existingActionConfig =
existingPkg.getActionConfigs().get(actionName);
704            if (existingActionConfig != null && LOG.isWarnEnabled())
705                LOG.warn("Duplicated action definition in package
[#0] with name [#1].", pkgCfg.getName(), actionName);
706        }

Can it be done? With reasonable modification of the struts framework maybe?

Thanks for reading,

Arne

Ok - bad choice of words. Validation annotations are processed by the
AnnotationValidationInterceptor. How it decides what to process I find a bit
hazy. There is super class ValidationInterceptor call made
actionValidatorManager.validate(action, context, method); 
which I assumed meant that the interceptor was looking to process only those
annotations on the method being called, rather than looking for all the
annotations in the class and applying them in turn (which is what the
VistorValidator seems to do unfortunately). I kind lost it at this point as
Struts found and executed my annotations although they were on methods
called by execute() rather than being placed on execute() itself.

Re: unicode breaks s:select?

[Alex Rodriguez Lopez]

Have you got this on top of JSPs?

<%@ page contentType="text/html; charset=UTF-8" %>

Patrick Cosmo, 15-12-2010 17:40:

Hi!

When using "s:select", if the list of data returned by my java class contains strings 
that have unicode characters in them, "s:select" fails to generate the entire tag, it 
dies at the unicode character.

For example, this tag:



When "userTypeList" has as its first item the string "Actualización_GZ" the

Struts 2 Conditional Validators?

[RogerV]

Hi

Is it possible to "conditionally" trigger a validator such that if
conditionA then use ValidatorX else use ValidatorY within the validation
framework out of the box? 

I have a scenario where a user is entering a serial number as a license key.
They can either enter a full serial number which licenses a particular
machine, or they can enter a "generic" license number, for example "DEF*"
which licenses all machine of a particular model. These keys end up in the
same column in the database and there is a single "serial Number field" in
the data capture form and hence a single attribute in my action. And of
course, they need validating differently.

The obvious solution to create two seperate input fields on the .jsp form
has been vetoed by the client. I have tried calling two seperate methods and
attaching the validators to the individual methods like;

public String execute() {
if (licenseId.endsWith("*")) {
addGenericLicense(licenseId);
} else {
addSpecificLicense(licenseId);
}
return SUCCESS;
}

 

@CustomValidator(fieldName="licenseId",type="SpecificLicense",message="Invalid
License key")

private void addSpecificLicense(String licenseId) {
getNewUserDTO().addSpecificLicense(licenseId);

}


@CustomValidator(fieldName="licenseId",type="GenericLicense",message="Invalid
Generic License key")
private void addGenericLicense(String licenseId) {
getNewUserDTO().addGenericLicense(licenseId);

}

but that doesn't work either - it looks like when either method
(addGenericLicense() or addSpecificLicense() is executed, all the validators
for the field licenseId are called and both validators fire.

I could of course, just write a validate() method in my action, but I would
like to keep the validators as I can re-use them elsewhere, so if there's no
way to have an "either/or validator" through the framework, I was wondering
if there is way of "nesting" the validators. Something along the lines of
having one single validator for the license key that programmatically calls
the correct validator internally? After looking at the ValidationInterceptor
I've had a try at calling a validator programmatically within my action with 

if (licenseId.endsWith("*")) {
GenericLicenseValidator validator = new 
GenericLicenseValidator();
validator.setValidatorContext(new 
DelegatingValidatorContext(this));
validator.setFieldName("licenseId");
try {
validator.validate(this);
} catch (ValidationException e) {
e.printStackTrace();
}
}

but this is giving me null pointer exceptions and I don't know if this is
because my code is wrong or because it just insn't going to work. So if
anyone could point me to examples of programmatically calling a validator I
would appreciate it.

Regards

Re: execAndWait Interceptor

[Zoran Avtarovski]

Sorry about the delayed response. I have been busy with xmas crap (ba
humbug).

The way we implement an ajax solution is to create a new thread, with a flag
stored in the session and poll the server using a jquery ajax call every 10
seconds. The ajax call returns a json response which has the flag value as
its first item and then relevant data if the process is complete.

The beauty of this is we have no page refreshes and when the process is
complete use the ajax response to either display the info or a link to the
report.

Z.
