Validator and Form Bean

[Suresh Addagalla <su...@wipro.com>]

Hi,

Does Struts Validator *pass back* the form bean object if a validation
fails? Or does it pass back only the errors?

My scenario is as follows. I have a page for creating a "Service". I
enter all the data and submit it. Assume that the validation fails. In
this case, along with the error message, I should display the submitted
values so that the user can correct them and re-submit. But now, my
whole form is not getting displayed because I am not getting the form
bean back. Any thing I am missing? **Must the form bean be in session
scope if I want this functionality?**

Thanks,
Suresh

You actually are getting returned to the page successfully if
validation fails or are null pointer exceptions showing up? I believe
you are going to have to create your own subclass of DynaValidatorForm
and then provide a way in the reset method to reset the Vectors. You
would then use this subclass in your form-bean
<form-bean name="servicesForm"
 type="suresh.package.MyDynaValidatorForm">

Yeah, I seem to be setting up struts-config correctly as it works fine
if I change the scope to "session". Here is the config:

Form-bean related config:

<form-bean name="servicesForm"
type="org.apache.struts.validator.DynaValidatorForm">
	<form-property name="serviceSets" type="java.util.Vector" />
	<form-property name="services" type="java.util.Vector" />
	<form-property name="serviceSet" type="java.lang.String" />
	<form-property name="service" type="java.lang.String" />
	<form-property name="announcementStartDate"
type="java.lang.String" />
	<form-property name="announcementEndDate"
type="java.lang.String" />
</form-bean>

Action mapping related config:

<action path="/services" type="prwp.action.ServicesAction"
name="servicesForm" scope="session" validate="true" parameter="task"
input="/services.jsp">

<exception type="com.nokia.ipdc.ss.prwp.service.DjapiException"
key="error.dberror" />

<forward name="Success" path="/services.jsp" />
                 
</action>

Thanks,
Suresh

No, the FormBean can have request scope. How are you setting up the
form bean into the page initially? Are you sure you are setting it up
correctly in the struts-config.xml file? Maybe you could paste that
part of the code here.
