How does one get the "validate" method to be called?
Hi,
My action is extending ActionSupport and overriding the "validate" method.
However, the validate method is not being called.
I have set the form tag validate attribute to true, but it makes no
difference.
What am I missing?
Thanks.

That would seem to suggest that the validation interceptor relies on
some work done by one of the interceptors you've removed from your
stack, no? Try listing all the validators that are in the default stack
and then commenting out the ones you don't want, one at a time, until
you identify which one you need to retain.

"workflow" interceptor used to call "validate" in 2.0.x, on 2.1
"validate" is called by the "validation" interceptor.

Just to clarify, the following works as desired:
<action name="toHtml" method="toHtml"
class="com.tchegbe.demo.action.ToHtmlActions">
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="params"/>
<interceptor-ref name="workflow"/>
<result name="input">toHtmlUtilityViewDef</result>
</action>
The action validate() method gets called properly by the Workflow
Interceptor.

Ok, I found the issue.
The Workflow Interceptor is the one that calls validate.
Hence, that's the interceptor I needed.
The application now works fine.
Thanks for all the help Dave.

A break point in debug mode.
Again, I get to the break point if I use the default stack as follow:
<action name="toHtml" method="toHtml"
class="com.tchegbe.demo.action.ToHtmlActions">
<interceptor-ref name="defaultStack"/>
<result name="input">toHtmlUtilityViewDef</result>
</action>

Thanks Dave.
In fact, my problem relate to an interceptor stack problem.
If I use the defautStack, it works.
But if I do the following it does not:
<action name="toHtml" method="toHtml"
class="com.tchegbe.demo.action.ToHtmlActions">
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="params"/>
<interceptor-ref name="validation"/>
<result>toHtmlUtilityViewDef</result>
</action>

Right now, I am forced to define a different namespace for each group of
actions with a different default stack.
Unlike the example discussed thus far, my action definitions don't specify
an interceptor.
The code posted is a little unique in that only this action uses the shown
set of interceptors.
So, this is what I do:
package x-name namespace X -> default stack -> actions
package y-name namespace Y -> different default stack -> actions
I wish I did not have to define a different namespace just to be able to
define different default stacks.

This is the default stack:
<interceptor-stack name="defaultStack">
<interceptor-ref name="exception"/>
<interceptor-ref name="alias"/>
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="prepare"/>
<interceptor-ref name="i18n"/>
<interceptor-ref name="chain"/>
<interceptor-ref name="debugging"/>
<interceptor-ref name="profiling"/>
<interceptor-ref name="scopedModelDriven"/>
<interceptor-ref name="modelDriven"/>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="checkbox"/>
<interceptor-ref name="staticParams"/>
<interceptor-ref name="params">
dojo\..*
</interceptor-ref>
<interceptor-ref name="conversionError"/>
<interceptor-ref name="validation">
input,back,cancel,browse
</interceptor-ref>
<interceptor-ref name="workflow">
input,back,cancel,browse
</interceptor-ref>
</interceptor-stack>
There is just no logical reason as to why my stack would not work.
Again, here is my stack:
<action name="toHtml" method="toHtml"
class="com.tchegbe.demo.action.ToHtmlActions">
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="params"/>
<interceptor-ref name="validation"/>
<result name="input">toHtmlUtilityViewDef</result>
</action>
servletConfig, fileUpload, and params are called just fine.

So, as I was saying, I don't like having to define multiple namespaces just
to be able to define a default stack for a different group of actions.
In the last example, if I give package B a namespace, it will work with each
package having its own default stack.

When you specify a default stack for a package in which an action is part of,
you do not have to specify an interceptor or interceptor stack on the action
mapping.
This makes maintenance far easier.
In any case, I am referring to being able to do this:
<package name="A" extends="struts-default">
<interceptors>
<interceptor-stack name="emptyStack">
<interceptor-ref name="empty"/>
</interceptor-stack>
<interceptor-stack name="aGivenStack">
<interceptor-ref name="something"/>
<interceptor-ref name="something2"/>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="emptyStack"/>
<action name="action" class="my.package.AClass">
<result>aPage.jsp</result>
</action>
</package>
<package name="B" extends="A">
<default-interceptor-ref name="aGivenStack"/>
<action name="action" class="my.package.BClass">
<result>aPage.jsp</result>
</action>
</package>
The only thing preventing being able to do that, is that the default stack
defined in package B will override the default stack define in package A
because they have the same namespace.

I also have this:
<interceptors>
<interceptor-stack name="emptyStack">
<interceptor-ref name="empty"/>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="emptyStack"/>
So:
1. I override the default stack.
2. I specify the exact interceptor(s) I need per action.
This is to avoid useless processing.
There is a fix in the work (a dtd fix) that will enable me to have a truely
empty stack.
Currently, the dtd forces you to define at least one interceptor whereas
there is no requirement to have an interceptor in a given stack.

Dave,
I have to disagree with you on customizing the interceptors.
It is just sloppy to use a generic stack that calls every interceptor.
Important issues also get lost when you do that.
The true issue with Struts2 is the poor documentation.
Worst is the fact that some of the defaults just aren't smart.
I really wish there was a way to group actions for the purpose of applying
default stacks without being forced to define a namespace or overriding the
default stack of an existing namespace.
