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.

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.
