Lukasz Lenart commented on WW-3954:
-----------------------------------
Validation errors are returned as a JSON object, check to docs [1]
{code:javascript}
{
"errors": ["Global Error 1", "Global Error 2"],
"fieldErrors": {
"field1": ["Field 1 Error 1", "Field 1 Error 2"],
"field1": ["Field 2 Error 1", "Field 2 Error 2"]
}
}
{code}
so if your success: directive looks like this:
{code:javascript}
...
success: function(response) {
if (response.errors || response.fieldErrors) {
// handle errors -> showErrors()
} else {
// handle normal logic -> processResponse()
}
}
{code}
When you active validateOnly, only validation will be performed, action result
will not be returned - you can use that just to validate the form data - not to
business logic.
To create a Maven project I use archetypes, you can do this as below:
{noformat}
mvn archetype:generate
{noformat}
or
{noformat}
mvn archetype:generate -DarchetypeCatalog=http://struts.apache.org/
{noformat}
and I'm using IntelliJ IDEA which natively opens Maven based project - directly
from pom.xml and to launch them I'm using Maven Jetty plugin - you can see
examples in the Struts2 apps [2]

> Ajax Validation is broken (json)

> Key: WW-3954
> URL: https://issues.apache.org/jira/browse/WW-3954
> Project: Struts 2
> Issue Type: Bug
> Components: Plugin - JSON
> Affects Versions: 2.3.1, 2.3.1.1, 2.3.1.2, 2.3.3, 2.3.4, 2.3.4.1
> Environment: Struts 2.3.4.1, Jquery 1.3.1, Struts json plugin 2.3.4.1
> Reporter: COMBEAU
> Assignee: Lukasz Lenart
> Priority: Minor
> Fix For: 2.3.9

> Hello,
> I have find an issue on Struts 2.3.4.1. I have made a migration from Struts
> 2.1.8 to Struts 2.3.4.1 and I have seen that the Ajax Validation doesn't work
> anymore.
> Moreover, when I would like to make the validation of my form in Ajax I seen
> that response was already "success" even if one or more fields are in errors.
> I think it's not normal. In Struts 2.1.8 when fields are in errors the
> response of an Ajax call is "error" not "success"
> To correct this issue I have made a workaround. In the
> JSONValidationInterceptor, if the buildResponse method have "/*" in the first
> append and "*/" in the last it correct the problem...
> why this :
> {code:java}
> protected String buildResponse(ValidationAware validationAware) {
> //should we use FreeMarker here?
> StringBuilder sb = new StringBuilder();
> sb.append("/* { ");
> ...
> sb.append("} */");
> /*response should be something like:
> * {
> * "errors": ["this", "that"],
> * "fieldErrors": {
> * field1: "this",
> * field2: "that"
> * }
> * }
> */
> return sb.toString();
> }
> {code}
> as been replaced by this :
> {code:java}
> protected String buildResponse(ValidationAware validationAware) {
> //should we use FreeMarker here?
> StringBuilder sb = new StringBuilder();
> sb.append("{ ");
> ***
> sb.append("}");
> /*response should be something like:
> * {
> * "errors": ["this", "that"],
> * "fieldErrors": {
> * field1: "this",
> * field2: "that"
> * }
> * }
> */
> return sb.toString();
> }
> {code}
> Is this a real issue ?
