help with execAndWait

Hello,

 

I am trying to use the execAndWait interceptor. My struts.xml looks
like:

 

<action name="foo" method="input" class="org.lls.classA">

<result name="input">foo.jsp</result>

</action>

<action name="foo_process" method="processFoo" class="org.lls.classA">

<interceptor-ref name="defaultStack"/>

<interceptor-ref name="token"/>

<!--

<interceptor-ref name="execAndWait">

<param name="delay">100</param>

<param name="delaySleepInterval">50</param>

</interceptor-ref>

-->   

<result name="success">foo-success.jsp</result>

<result name="wait">foo-wait.jsp</result>

<result name="input">foo.jsp</result>

<result name="invalid.token">foo.jsp</result>

</action>

 

Now in my action class, I have a bean with appropriate getter and setter
methods on it. The foo.jsp has a form which is mapped to attributes of
the bean in the action class. For example, <s:textfield
name="myBean.name".../>. The form tag looks like <s:form
action="foo_process"...>

 

When I run the application with the given struts.xml above, myBean gets
populated properly in the processFoo method (I'm assuming the Parameter
interceptor does that).

 

However, when I uncomment and try to use the execAndWait interceptor,
for some reason, myBean comes out to be NULL in processFoo().

 

Any help will be appreciated.

 

- Osman

No, I am using struts 1.1, I would like to implement the following case:
In valiation.xml:

 <form name="/myAction">
		 <!--if submit button 1 clicked, I validate the
following field>-->
		<field property="myProperty" depends="required">
			<msg name="required" key="error.key1" />
		</field>   

		<!--if submit button 2 clicked, I validate the following
field>-->
		<field property="name" depends="myValidator">
			<msg name="myValidator"	key="error.key2" /> 
		</field>
</form>  


I don't want to validate both fields at the same time when just one
submit button is clicked. Your helps are appreciated!

Are you using Struts 2 at all?

You can still use the generated HTML as a template to create your own
HTML,
although... not sure why you wouldn't just use the tag in this case.

Hi,

You can override method 
 public String getValidationKey(ActionMapping mapping,
                                   HttpServletRequest request) {..}

>From your ValidatorForm (it doesn't matter if it is dyna or not)

And return different validation keys for each button pressed.

Validation key identify the rules of validation.

The validation file will look then something like:

<form name="myAction_button1">
		 <!--if submit button 1 clicked, I validate the
following field>-->
		<field property="myProperty" depends="required">
			<msg name="required" key="error.key1" />
		</field>   
</form>

<form name="myAction_button2">
		<!--if submit button 2 clicked, I validate the following
field>-->
		<field property="name" depends="myValidator">
			<msg name="myValidator"	key="error.key2" /> 
		</field>
</form>

Oh, wow.

Does validwhen[1] not exist in S1.1? You can always create a custom
validator
as well if you find your validation stretches what's easy to do with the
existing validation configuration possibilities. You may also be able to
combine declarative validation (via XML) and Java-based validation, although
it's been a pretty long time since I've thought about that :)

You can do it by having 3 different methods such as

method1() method2() method3() and then have 

validateMethod1() validateMethod2() validateMethod3() 

then in your form 

<s:submit key="button.method1" method="method1"/> 
<s:submit key="button.method2" method="method2"/> 
<s:submit key="button.method3" method="method3"/> 

or you can do by using action aliases and have three validation xml
files.

Hello coworkers,

I have a questions regarding the struts validation..., say I have three
text fields to be validated in struts validation, and three submit
buttons as well. When I submit one buttion, I only need to validate one
field, and when I click on the other submit button, I need to validate
the other field. Currently, all three fields are validated even though I
don't need to. Is there any way to overcome this issue?

Thanks.

If you set those parameters in a stack definition, and then refer to 
that stack in the action, what happens?

I turned debug level logging for struts and xwork packages.
I see that the ParametersInterceptor is being called indeed for both
scenarios (with or without execAndWait)

However, one interesting thing is when I comment out the "delay" and
"delaySleepInterval" params from the execAndWait interceptor, I don't
get this problem.

Maybe this problem has to do with timing? Not sure but this is weird...

You should be able to tell from the call stack which interceptors have 
been called--can you verify that parameters is included?

I don't know if including more than one interceptor-ref inside the 
action definition uses all of them (in what order?) or just the last 
one--I always define  the stacks I need separately and just refer to the

appropriate one within my action definition...

Does this created object contain any references to other DB objects?

That is an interesting point. The bean is a hibernate object, however, I
am not retrieving it from the database, but rather only trying to
populate it from the form values. 

So, it's a CREATE operation if you look at it from the CRUD perspective.

After reading on HibernateAndSpringEnabledExecuteAndWaitInterceptor,
what I understand is it would be necessary for objects being populated
from the database (using Hibernate obviously)

Unless I'm mistaken....
