JSF 2 button doesn't work on the same form

[shivangi redkar]

this is the code which i have entered..
actually the problem is that i cant delete from my database of i have not entered values in the 2 input texts provided below. 
i knw this is because of the required attribute provided there but the required attribute need to be there as the 2 fields are imp and need to be entered by the user. 
when i remove this attribute from the tags it works fine but blank values may get inserted in the database so i would like u to provide me with a method 
where in i can delete the value from the databse using the delete button and also keep the reuired attribute there. 
hope my difficulty is understood waiting for a answer urgently please reply thank u..

In JSF, anything that fails validation will suppress the action process. That's a fundamental design aspect of JSF designed to ensure that only "good" data is posted to the backing bean before an action can execute.

You want to have your cake (non-required items) and eat it (requiring them) too and that doesn't work.

However, looking at your example, I think a different approach will serve.

Right now, you appear to have the entire view wrapped in one big form, even thought the edit and delete sections appear to both be independent of each other. If you split the page definition into 2 forms - one for the edit part and one for the delete part, that would eliminate your problem. Only one form can be submitted - the one that contains the commandButton that the user clicked on. And validation only applies to the submitted form, not to any other form on the page.

thank you Tim but main goal is to have it in the single form itself. is there a way out may be by using rich faces or something

[Tim Holloway]

Why should it be a "goal" to have everything in one form? A form is simply a collection of objects submitted as a unit and has no graphical characteristics other than the standard XML limitations of nesting elements. The user won't see the difference.
