Skip validation when form not submitted

[r vertet]

Hi,

how would you, using struts, create a form with validation (using the validator framework) and skip this validation when the form would be accessed without being submitted.

So let's say I have a form with 1 required field under /MyForm.do:

1. call /MyForm.do
2. empty form shows
3. user enters the data & submits the form to /MyForm.do
4. validator framework checks whether the required field has a value
5. if yes, action is executed

How would you do this in struts?

What do you mean by this? The steps you have mentioned in this post is how it works out normally, what is that we need to do differently?

No, if I add some validation to a form (like required field) then when I access the form the first time (that is, without a submit) the validation fires and shows a message like 'Field X is required'.

No, This should not happen. Struts provide javascript and server side validation, which one are you exactly talking about? Do you get a javascript alert? If yes, post your JSP code here.

It is pure server-side validation.

The following code shows an error-message when I first access the form via /TilesDemo.do:

struts-config:
    <action 
      path="/TilesDemo"
      type="my.classes.TilesDemoAction"
      name="lookupForm"
      input="tiles.demo">
      <forward name="success" path="tiles.demo"/>
    </action>

LookupForm.java:

	  public ActionErrors validate(ActionMapping mapping, HttpServletRequest req) {
		  ActionErrors errors = new ActionErrors();
		  
		  if (symbol == null || symbol.length() == 0) {
			  errors.add("symbol", new ActionMessage("errors.lookup.symbol.required", "ach ja"));
		  }
		  
		return errors;
		  
	  }

Maybe the solution for my problem is in the "Multi Page Forms"?

Anybody?

Hi Vertet, Could you post the action class method that you are using?

[r vertet]

The action is quite irrelevant because it is prevented from being executed by the validator. Anyway it is almost empty:

  public ActionForward execute(ActionMapping mapping,
    ActionForm form,
    HttpServletRequest request,
    HttpServletResponse response)
    throws IOException, ServletException {
	  
	  
	  log.debug("Entered action.execute; version '{}'.", version);
	  
    return (mapping.findForward("success"));  }

server-side validate(ActionMapping mapping, HttpServletRequest request) in your scenario won't execute..

Because you did not specify validate="true" attribute in the action tag.

check your action tag once..

validate="true" is the default, besides validation is firing. That is NOT the problem (please read the thread before you reply)
