Complex Form Bean Validation
Hi everyone,
I hope you might be able to help me with this issue. I want a form
bean to perform more complex validation than what is possible with the
property annotations. Think "if property A has the value X then
property B must not be greater than Y".
In Struts I would simply override the validate method. How do I do
this in Beehive?
Thanks for your help,
Philipp

Hi Philipp,
Looks like you may have found a bug. You can open a bug at Apache,
https://issues.apache.org/jira/browse/BEEHIVE
...and attach your simple reproducer/test for this issue.

Re: Complex Form Bean Validation
Posted by Philipp Jardas <ph...@jardas.de>.
Hi Carlin,
thanks a lot for the tip about the validator interface, this is
exactly what I was looking for.
Not a new problem arised, maybe hopefully you can help me out with
this as well. I am using page flow controller inheritance.
public class ParentController extends ... {
@Jpf.Action( ... validationErrorForward = Jpf.NavigateTo.currentPage )
public Forward submit(FormBean form) { ... }
}
The child flow controller has inheritLocalPaths set to true and does
not overwrite the action method.
When I submit the form bean, which has been enhanced with the
Validator interface, and the validation fails, I would expect the user
to be forwarded back to the input page. However, I receive an
exception:
org.apache.beehive.netui.pageflow.NoPreviousPageException: No relevant
page for return-to="currentPage"
If I use a path in the validationErrorForward instead of NavigateTo,
no exception occurs but no JSP is being rendered. =(
Do you have any ideas?
Thanks a lot,
<P>

Re: Complex Form Bean Validation
Posted by Carlin Rogers <ca...@gmail.com>.
If you cannot come up with a the custom validator that works for you,
you can implement a validate() method as you inquired about in your
original post. Just make the super class form bean implement the
org.apache.beehive.netui.pageflow.Validatable interface and write a
general validate() method.
http://beehive.apache.org/docs/1.0.2/netui/apidocs/javadoc/org/apache/beehive/netui/pageflow/Validatable.html
The Validatable interface validate() method would be called when data
is posted to any page flow action that takes the given bean as its
argument (Note, the action needs validation turned on by including the
validationErrorForward in the @Jpf.Action annotation).
Or, if you extend your super class form bean from Struts ActionForm,
you could override its validate() method and it would be called by the
framework.
Kind regards,
Carlin

RE: Complex Form Bean Validation
Posted by Phillippe Camus <Ph...@imail.org>.
Hi Philipp,
Not sure if that is what you are looking for, but you can create custom
validators.
You need to reference them in a deployment descriptor named
"custom-validator-rules.xml":
<form-validation>
<global>
<validator name="validateNameIsString"
classname="org.foo.portal.utils.customValidator.CustomRules"
method="validateNameIsString"
msg="nameIsStringError"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
javax.servlet.http.HttpServletRequest,
javax.servlet.ServletContext" >
</validator>
</global>
</form-validation>
Then in your CustomRules class you would implement your validation
method:
public static boolean validateNameIsString(Object bean, ValidatorAction
va, Field field,
ActionMessages errors, HttpServletRequest
request,
ServletContext servletContext)
{
You can access the fieds in your FormBeans like this:
ValidatorUtil.getValueAsString(bean, field.getProperty());
And then submit the error for the Netui tags: errors.add(field.getKey(),
Resources.getActionError(request, va, field));
Then in your form bean:
@Jpf.ValidatableProperty(validateCustomRules = {
@Jpf.ValidateCustomRule(rule = "validateNameIsString", messageKey =
"nameIsStringError") })
public String getFirstName() {
return firstName;
}
You can pretty much do whatever you want in the CustomRules class. Hope
this helps.
Best regards,
Phil

Hi Zuber,
Thanks again for the swift response. However, I am not able to find
the base class "TaggedObject" you mentioned, neither in the Beehive
nor in the Struts libraries. Are you sure about the name?

Hi Philipp,
I am not sure if this is correct way to do but you can do that by creating a
bean class by extending 'TaggedObject' class it has validate method which
you can override .
Hope this will help you.

Hi Zuber,
thanks for your reply, though it didn't catch what I was thinking of.
I am, of course, aware of the property annotations. Let me give an
example of what I want to do:
public class TestForm {
public long getA() { ... }
public long getB() { ... }
public void validate() {
if (getA() > 3 && getB() < 4) {
// Add error message to B: "Must be smaller than 4 if A is
greater than 3".
}
// even more complex validation scenarios...
}
}
How could I possibly do this with annotations that always refer to a
single property?
Thanks,
<P>

Hi Philip ,
You can do this my putting validateProperty anotation of every getter of the
property.
for ex:
@Jpf.ValidatableProperty(validateMaxLength = @Jpf.ValidateMaxLength(chars =
20, messageKey = "error message you can set"), validateMinLength =
@Jpf.ValidateMinLength(messageKey = "errror message you can set ", chars =
5))
public String getUser_id(){
return user_id;
}
You can also get help from beehive documentation . Hope this will help you.
Regards,
Zuber
