Can you please show me how to add rows to table via jQuery which later on are bound with spring.

Thanks

Many thanks for your comments I am glad it helped you

Cheers!

I guess in the controller submit method you could add the BindingResult parameter and implement your own validator.

You could also use the new JSR-303 Bean Annotation validation on each individual student and that should vailidate so the onSubmit method would become:

@RequestMapping(method = RequestMethod.POST, value="/processClassForm.page")
protected String onSubmit( @ModelAttribute("classCommand") @Valid ClassCommand classCommand,  ModelMap model )
{
	model.addAttribute("savedClass", classCommand);
	return "formResult.view";
}

In that case, rather than using the @ModelAttribute function you could just populate the required object (by placing into the ModelMap) in the GET annotated controller method in that case the object would be populated when and only when the form is displayed.

If you need to pre-populate the Class Command in this example such as calling into a database as you mention you can do so by all means. The AutoPopulating list of the class command can be updated in the same way as a java.util.List

I see one issue with your code and that is that getClassCommand will be called every time @ModelAttribute(“classCommand”) is injected.

What about if you need your ClassCommand instance to be “kept alive” between the calls?
That would be necessary if you did something else than just “ClassCommand classCommand = new ClassCommand();” in you getClassCommand() method. Loading a ClassCommand from the database for instance.

I have tested the download and everything seems fine.

After downloading and extracting the Zip file. In Eclipse Click File then Click Import and choose ‘Existing projects into workspace…’ then on the next screen choose the downloaded folder.

After importing everything should build OK?
