Re: Form validation without a form component

Thanks for the suggestion Martijn. 
I tried return new FormComponent[0]; and got exactly the same error.

I think my use-case is quite fringe, so I have resigned myself to using the
hidden field that you previously suggested.

Re: Form validation without a form component

Posted by scotthendo <sc...@gmail.com>.
Hi Antoine,

I am doing something similar and was wondering if you could help. I am
trying to validate a large form by overriding the onValidate method but when
I do, all the form values are null.

Some code snippets:

public final class DatasetForm extends Form
    {
        private final DatasetTO dataset = new DatasetTO();
        
        public DatasetForm(final String componentName)
        {
            super(componentName);
            
            add(new TextField("orgName", new PropertyModel(dataset,
"orgName")));

       }

        public final void onSubmit()
        {
              System.out.println(dataset.getOrgName()); // this works fine
and displays the value
        }


         public final void onValidate()
        {
           System.out.println(dataset.getOrgName()); // here it is set to
null
         } 
}

So how can i access the form values from onValidate()

Thanks in advance, scott.

for the archive-searchers :)

simply override onValidate in the Form class, check your listsize
there & call error() when applicable
