An interceptor that makes sure there are not validation errors before allowing the interceptor chain to continue. This interceptor does not perform any validation.

This interceptor does nothing if the name of the method being invoked is specified in the excludeMethods parameter. excludeMethods accepts a comma-delimited list of method names. For example, requests to foo!input.action and foo!back.action will be skipped by this interceptor if you set the excludeMethods parameter to "input, back".

Note: As this method extends off MethodFilterInterceptor, it is capable of deciding if it is applicable only to selective methods in the action class. This is done by adding param tags for the interceptor element, naming either a list of excluded method names and/or a list of included method names, whereby includeMethods overrides excludedMethods. A single * sign is interpreted as wildcard matching all methods for both parameters. See MethodFilterInterceptor for more info.

In DefaultWorkflowInterceptor

applies only when action implements com.opensymphony.xwork2.Validateable

1. if the action class have validate{MethodName}(), it will be invoked
2. else if the action class have validateDo{MethodName}(), it will be invoked
3. no matter if 1] or 2] is performed, if alwaysInvokeValidate property of the interceptor is "true" (which is by default "true"), validate() will be invoked.

Parameters

• inputResultName - Default to "input". Determine the result name to be returned when an action / field error is found.

Examples

<p/>
<action name="someAction" class="com.examples.SomeAction">
    <interceptor-ref name="params"/>
    <interceptor-ref name="validation"/>
    <interceptor-ref name="workflow"/>
    <result name="success">good_result.ftl</result>
</action>
<p/>
<-- In this case myMethod as well as mySecondMethod of the action class
       will not pass through the workflow process -->
<action name="someAction" class="com.examples.SomeAction">
    <interceptor-ref name="params"/>
    <interceptor-ref name="validation"/>
    <interceptor-ref name="workflow">
        <param name="excludeMethods">myMethod,mySecondMethod</param>
    </interceptor-ref name="workflow">
    <result name="success">good_result.ftl</result>
</action>
<p/>
<-- In this case, the result named "error" will be used when
       an action / field error is found -->
<-- The Interceptor will only be applied for myWorkflowMethod method of action
       classes, since this is the only included method while any others are excluded -->
<action name="someAction" class="com.examples.SomeAction">
    <interceptor-ref name="params"/>
    <interceptor-ref name="validation"/>
    <interceptor-ref name="workflow">
       <param name="inputResultName">error</param>
        <param name="excludeMethods">*</param>
        <param name="includeMethods">myWorkflowMethod</param>
    </interceptor-ref>
    <result name="success">good_result.ftl</result>
</action>
