Re: Validation is called before form is populated from my database
Finally, I found two valuable solutions to my problem.
The first one is MappingDispatchAction, as suggested
by Hubert. It is efficient but I dislike to have so
much entries in my struts-config (my application is
going big enough)
I found a good explanation for it by the frustrated
programmer (who gives us some remarks about Struts
which were helpful for me)
http://frustratedprogrammer.blogspot.com/2004/07/struts-121-mappingdispatchaction.html
The second one is to redefine the methode "validate"
in my form-bean (EditionPersonneForm, which extends
validator.ValidateForm) and add a condition in it,
which enables validation or not, according to my
dispatch parameter "do".
public ActionErrors validate(ActionMapping mapping,
javax.servlet.http.HttpServletRequest request)
{
if (someCondition)
{
return new ActionErrors();
}
return super.validate(mapping, request);
}
Thanks again, Hubert !

Re: Validation is called before form is populated from my database
Another option is to switch to MappingDispatchAction* so you can set different attributes for the different situations that your Action needs to handle.

Re: Validation is called before form is populated from my database
No, always respond to the user list when it's relevant to the question you posted. This way, other people can offer solutions as well, and those having the same problems will get to hear/read what the solution is. Since you're extending DispatchAction, you probably should turn off automatic validation and handle it yourself. Search the archives for discussion on automatic validation, it's been discussed a lot the past few months.

Re: Validation is called before form is populated from my database
Unfortunately EditerPersonneAction do extend DispatchAction (using parameter "do") !

Re: Validation is called before form is populated from my database
It seems that you're trying to prepopulate a form with values from the DB before showing it to the user. So, you have 1) call /EditionPersonne to prepopulate the form 2) show EditerPersonne.jsp to display the form 3) submit the form to /SomePathLikeSubmitPersonne If so, you don't need to specify the "form" attribute in /EditionPersonne. The "form" attribute identifies the input form for that Action, to carry the data being submitted to that Action. Try removing the "scope", "form" and "input" attributes to /EditionPersonne, and specify them instead on the Action to which the form will be submitted to. On the other hand, if EditerPersonneAction extends a DispatchAction class, send another message and we'll offer a different solution.

Re: Validation is called before form is populated from my database
Hi, As much I know if you need to load data when the page is load before the validation is called. You may load data when the action is called and there could be another action associated with the Submit button's page which will check the validation. I'm not sure whether it make you clear or not or solve the problem you asked for. Let me know if you need more clear explanation about my procedure. Thanks Mahbub
Validation is called before form is populated from my database
Hello, I'm currently having a problem with the Struts validator. I have a very simple Struts bean "EditionPersonneForm" (extending ValidatorForm) associated with an action "EditerPersonneAction" and a JSP form "EditerPersonne.jsp" [From struts-config.xml] [end of listing] The matter is that the method validate() is called BEFORE the form is displayed. So if the Struts bean is filled in with wrong values at this very moment, the validator causes an error and Struts redirects me to the "input" error page, and the action (which populates the form with the right data from the database) is never called ! Does anyone have a clue ?
